                                  Introduction


INTRODUCTION

Program Description

BiModem is  a new communications protocol that allows simultaneous bidirectional
file transfers.  Yes, BiModem  can upload  while downloading.  Imagine the  time
savings  if you could  upload with  Zmodem (tm)  and YmodemG  efficiencies while
downloading at the same  efficiency simultaneously. The applications for  such a
protocol are  many,  and  I will  not  try to  cover  them here.  Everyone  from
occasional  BBS  users  to  full  time  network  managers  will  appreciate  the
advantages of exploiting  full duplex operations. Even for those  with small and
moderate volumes of data to transfer, the time savings can be  very significant.
Please do not expect  a 50% decrease in your total modem transfer time. This can
only  be achieved  when the same  amount of  information is transmitted  in both
directions,  and does not  account for the  overhead of specifying  the lists of
files to download and upload.

If that feature is not enough to  get you really excited, how about the  ability
to chat while  the transfer is going  on? Chatting will impact  your throughput,
but since most of us are slow typists the impact is usually minimal.

Two methods  of automatic  recovery are  provided. This  first is  the one  that
everyone else provides. If a file exists with the same name, date, and time, but
different sizes then BiModem  picks up where it left  off. The second method  is
for boards that like to  have the date and time stamp reflect the  time the file
was  uploaded.  It  will rename  a  file  into  an  abortion  directory  if  the
transmission is prematurely terminated.  Then when the user calls back to finish
the upload it will restart where it left off.

A  refresh mode of uploading is provided.  It verifies the contents of two files
and only sends the data where it encounters discrepancies. The verification part
takes  about 20 seconds per  200k at 2400 baud. If  it finds several consecutive
discrepancies  it then switches  to a normal  upload. This is  perfect for large
transaction files where the  only thing that ever changes  is at the end of  the
file  where transactions are added.  Imagine refreshing a  10 meg file  in a few
minutes that only had 20k modified at the end.

Auto Verification insures  that the entire  file was accurately transmitted  and
can  be  switched  on at  the  user's  discretion. While  this  is  normally not
necessary (BiModem already  uses 32bit CRC's to  insure accuracy), it is  a good
feature to  have available  for those  critical transmissions  and is  efficient
enough that you may want to use it routinely.

BiModem  has more than  just *  name handling.  You can create  a large  list of
upload and download requests before you even sign on. Create an entire evening's
worth of requests and let your computer do the rest.

Multiple  directories can be searched  for the file.  You can provide  a list of
directories for BiModem to  search. Imagine requesting a  download of *.GIF  and
receiving every GIF  file the  board has available.  Not just  the ones in  your
current area.

                                  Introduction


You also can  supply a list of directories  for it to scan  for duplicates. Upon
finding  a duplicate in  any of  the directories  in the list  it will  stop the
transmission of that file.

BiModem  is both  Double Dos  and Desqview  aware. For  both  fine multi-tasking
software additions  it intelligently informs them  when it is idle.  This allows
other tasks to get more  of your machine's time. It also means  that the display
is as fast and intelligent as it can be.

All this power is  provided to you by a  menu. This makes the functions  easy to
remember and fast to get to.

BiModem is  fully configurable to  allow as  much or  as little  access to  your
system as you desire. You can allow full  path specifications on both ends. If a
file already exists, you  can replace the file directly, or  simply run a verify
to revise only the parts that have changed. You may request that the source file
be deleted  on a  successful transmission  or you  can disable  this feature  so
others cannot delete files from your system.

File level password  protection is available. When  someone uploads a file  to a
BBS  they also can supply a password so  that subsequent callers can only access
the file if they know the correct password.

Four  different  methods  are  available  to  maintain  your  file  transmission
requests. You can mark files to be  sent by walking through your hard disks  and
selecting them. You  can scan a previously  downloaded list to select  files you
want  to download while you are offline. There  is a hot key program provided so
that you can mark files that are displayed  on screen. And there is the original
request list maintenance program.

For registered users there are even more features:

Forget a file? No need to wait until  the current transfer is done. You can  add
transfer  requests  while transferring  other files.  You  also can  kill single
requests on either the send or receive side.

Surely  by now  you  are wondering  if  this is  all  BiModem does.  The  answer
unfortunately for today is yes, but  the future holds even more exciting  things
for  BiModem. There just wasn't time  to add all the  features for this release.
But, upgrades are  free as long  as you are  willing to call  our BBS to  attain
them.

The future will offer additional features such as:

Sub-Directory  inclusion: Tell BiModem you want sub-directories included, and it
will copy all files matching the * name from the specified directory on down the
tree and  create a similar tree  on the receiving  end (if allowed and  the tree
doesn't already exist).

                                  Introduction

Dialing lists and  scripts: Build  a list  of phone #'s  to call,  tell us  what
script to use,  what transmission request file to  use, and go to  bed (let your
computer do the walking).

File Compression: for even faster transfer rates.

Machine Requirements

BiModem requires a PC/XT,AT,or 386 with at least 100k of memory available to it.
It will work on  MicroSoft DOS 2.0 and higher.  Unbuffered communications boards
work best. The  buffered communications boards will  work, but they will  have a
negative impact on the BiDirectional file transmissions and when chatting.

BiModem Files

BiModem is comprised of the following files:

BiModxxx.Zip - This is the shareware version of BiModem. The xxx represents the
          version number. For instance 111 would be version 1.11.

BiModem Installation and Execution

BiModem Installation

The easiest way to  get BiModem up and running  is to run Binstall. It  will let
you select the  communications program that  best describes your program  (Other
for  most), and  what directory  it resides  in. You  also will  be asked  which
communications port  your modem uses. The appropriate  files will then be copied
to your  communications directory.  Before running  this, you  should unzip  the
BiMod*.Zip file into a work directory from which the files may be copied to your
communications directory. If you are installing from a registered shipment disk,
you  can  either  copy  the  diskette  contents to  a  temporary  directory  for
installation or install from the diskette you receive.

When you  are done please refer to Appendix C  if you are installing BiModem for
use with a telecommunications  program. If you are installing BiModem  on a BBS,
then  you  should refer  to  the  interface software  documentation  for further
installation  information. Erik Labs  has many interface  programs available for
various BBSes on its  BBS (Valley of the Sun). The interface  programs read your
BBSes  configuration, establish an environment for BiModem to run in, and update
user and BBS statistics and file listings.

What communications program will you be using

This field identifies the type of communications software you will be using. The
valid entries  are listed below the  prompt on the  screen. What you  enter here
will decide if script files are needed  to run in that environment. It also will
determine which configuration  file will be used.  The ? of BiModem.Cf?  will be
replaced by the communications software type to determine what file to copy.

What communications port will you use (1-8)

This field identifies the  communications port you will be using.  If your modem
is attached to com1, then you need to specify  a 1. If your modem is attached to
com2, then  you need to specify  a 2, etc. Your  response will be  placed in the
appropriate BiModem.Cf? file.

Where do you want BiModem installed?

This field  identifies the  directory that  you want  to have  BiModem installed
into. Normally  this would  be your  communications programs  directory. For  GT
Powercomm, and some BBSes,  the directory should be a sub-directory  of the main
communications program's  directory. Please consult you  communications software
manual to see if they have any suggestions. If they don't mention anything, it's
probably  safe  to  install  BiModem  into  the  main  communications  program's
directory.

                           Installation and Execution

What is the path to your script directory

This field  is only applicable if you are using a terminal program that allows a
separate directory for script  files. It identifies the directory  that contains
all  your  script files.  Normally  this is  set  to the  main  terminal program
directory,  but some  terminal programs allow  you to  assign it to  a different
location. If you're  not sure where  your's is set  to, you probably  should set
this field to the main terminal program directory. The script files can be moved
to a different location later.

BInstall installation

After  you have filled  in all the  fields mentioned above,  BInstall will start
copying the appropriate files into the directories you told it to. If this is an
upgrade,  you  will notice  that  some  files  are skipped.  For  instance,  the
configuration file is always skipped  if one already exists in  the installation
directory. While the  files are being copied  you will see the  following screen
appear:

                           Installation and Execution

Now  that  you have  BiModem  installed  we will  cover  how to  use  it  with a
telecommunications package. The following  is a list of the normal  actions that
occur to execute BiModem.

1. You may  want to add  BiHot to your  AutoExec.Bat file. This  is a small  TSR
program that makes marking downloads a breeze.

2. Normally  you would want  to build the list  of transfer requests  before you
sign on to the BBS. This saves a lot of  time while you're on the BBS. There are
several  tools available  to do  this. You  can use  BiPath  to enter  both your
uploads and downloads. This  method is tedious and requires that  you know where
all the  files reside. BiMark  is available to  mark uploads from  an XTree like
list. BiList is available to mark downloads from a previously downloaded list of
files  on the BBS. You may use any or all these three methods to build your list
of transfer requests before signing on to a BBS.

3. Next you  would want to invoke  your telecommunications software and  have it
dial the BBS.

4.  While  you're  wandering through  the  bulletins,  and  browsing the  recent
uploads, you may  come across an additional  file that you want  to download. If
you  have previously  loaded BiHot,  then you  can easily mark  these additional
files from  your screen  display. Otherwise  you can  use BiPath  when you  come
across an additional file that you want.

5. When you're ready to transfer files, you can invoke remote BiModem. This will
allow you to type commands to the BBS such a F for  the files menu, or open 1 if
BiModem is  in a door. When Remote BiModem  automatically senses that BiModem is
up on the BBS it will bring BiModem up on your computer.

That's  all  there  is  to  it.  You're  now  witnessing  the  phenomena   of  a
BiDirectional transfer. Amazing isn't it.

                                     BiMenu


BiMenu - The menu for BiModem and its support programs

BiMenu is a customized menu for BiModem and its support programs. BiMenu and all
its sub-programs can  either be in  your current directory  or in the  directory
that BiMenu  is  loaded from.  It is  designed  to be  invoked  from a  terminal
emulator as a hot  key, or by jumping to DOS and invoking BiMenu (see appendixes
for interface information).

The Command Format is:

     BiMenu    [/?]
          [/A Abort Directory Path]
          [/B Baud]
          [/C Config_Path]
          [/E Decimal Character Number to Escape]
          [/F]
          [/I New Format Intercommunications Log Path]
          [/J Rejection List Path]
          [/L Comm Port]
          [/N Sending Directory/List Path]
          [/P Transfer List Path]
          [/Q]
          [/R Receiving Directory Path]
          [/S Size Limit]
          [/T Time Limit]
          [/W Password File Path]
          [/> Old Format Intercommunications Log Path]

/?

This displays the acceptable arguments.

/A Sending Directory/List Path

Tells BiMenu  what directory,  or list  of directories,  to pass  to BiModem  to
determine where files will  be sent from if the user does not specify a path. It
overrides the sending directory specified in the configuration file.

/B Baud Rate

Tells BiMenu  what baud  rate to  pass  to BiModem  for it  to use  in its  time
estimate. This value overrides the value specified in the configuration file.

/C Config_Path

Tells BiMenu what configuration path to use.  The default is BiModem.cfg in your
current directory. This argument, as with all BiMenu arguments is passed through
to programs that it invokes.




                                       13




                                     BiMenu

/E Decimal Character Number to escape

Tells BiMenu what escape character to pass to BiModem. See the /E argument under
BiModem for a description of what this argument does.

/F

This turns BiModem's DSZ receive logging off. Some bulletin board interfaces can
read a DSZ format log file, but they tend to get confused by the fact that there
are both uploads  and downloads in the log. They usually do not maintain correct
upload or download  statistics. By using the  /F argument these  interfaces will
maintain correct download  statistics, but not upload  statistics. This argument
will be temporary and it  will go away when all known interfaces properly handle
BiDirectional DSZ logging.

/I New Format Intercommunications File Path

Tells  BiMenu what file to pass to  BiModem for its use in communicating between
BiModem  and  BBS interface  programs. Without  this  argument BiModem  will not
generate this special log file.

/J Rejection List Path

Tells BiMenu  the  path of  file to  pass to  BiModem  that contains  a list  of
directories to  scan to  determine if  an incoming  file should  be accepted  or
rejected. It overrides the file specified in the configuration file.

/L Comm Port

Tells BiMenu what communications port  to pass to BiModem. This value  overrides
the value specified in the configuration file.

/N Sending Directory/List Path

Tells BiMenu  what path to pass BiModem  for its use in  determining where files
will be sent  from if  the user does  not supply a  path. Of  course if you  are
disallowing full paths (see BiConfig general options), then it would include all
file  requests.  This can  also be  the  path to  a  file containing  a  list of
directories  to  be  searched.  This  field  overrides the  information  in  the
configuration file.

/P Transfer List Path

Tells BiMenu what  transfer list path to  use. This argument overrides  the path
specified in the configuration file.

/Q

Tells BiMenu to  invoke BiModem in quiet  mode. Quiet mode is when  BiModem does
not display anything.



                                       14




                                     BiMenu

/R Receiving Directory Path

Tells BiMenu what directory  path to pass to BiModem for  its use in determining
where  to put files  that it receives.  This argument overrides  the information
stored in the configuration file.

/S Size Limit

Tells BiMenu what size limit to pass to BiModem. This value  overrides the value
specified in the configuration file.

/T Time Limit

Tells BiMenu what time limit in minutes to pass to BiModem. This value overrides
the value specified in the configuration file.

/W Password file path

Tells BiMenu what password file to pass to BiModem. This argument  overrides the
password file identified in the configuration file.

/> Old Format Intercommunications File Path

Tells BiMenu what file to pass  to BiModem for its use in determining  what file
to  use to communicate between BiModem  and BBS interface programs. Without this
argument BiModem will not generate this special log file.

Here is a sample screen for BiMenu:

Once this screen appears you  may use the up and down arrows to  position to the
appropriate selection. Once  the selection bar  is on the appropriate  selection
you can then  hit the enter key to  invoke that function. Alternatively  you can
type in  the  first character  of  the selection  to invoke  it.  Some of  these
functions are internal to BiMenu and some of them  invoke other programs. If the
function involves loading another program, then BiMenu will first try to load it
from the current directory.  If it can't find it  there, it will try to  load it
from  the directory  that BiMenu resides  in. We  will now briefly  describe the
selections available.

Download Capture from Local List

This selection  invokes the program  BiList. It allows  you to mark files  to be
downloaded from a previously downloaded list of files. Presumably on the  system
you are  connected to. Upon completion of BiList  control will return to BiMenu.
For further information on BiList see its chapter.

Mark Uploads from Disk

This selection  invokes the program  BiMark so that you  may mark files  on your
system to be uploaded. Upon completion of BiMark control will return  to BiMenu.
For further information on BiMark see its chapter.

Remote BiModem

This selection first invokes the program BiBat so that you  may start BiModem on
the  bulletin board  at the  other end.  BiBat is a  mini terminal  emulator. It
passes characters that  you type  on to  the comm port  and displays  characters
received  from the  comm port on  your screen.  It also monitors  the characters
received for the  space/backspace character sequence  that BiModem uses for  its
handshaking. Once BiBat recognizes a space/backspace sequence it terminates  and
BiMenu then invokes BiModem on your computer. Upon completion of BiModem, BiMenu
also terminates. This  should bring you back to your  favorite terminal emulator
software.

Host BiModem

This selection invokes  BiModem on  your computer. Upon  completion of  BiModem,
BiMenu also  terminates. This should  bring you  back to your  favorite terminal
emulator software.

Transfer List Maintenance

This  selection invokes the  program BiPath so  that you can modify  the list of
files to be transferred.  When BiPath terminates control will return  to BiMenu.
See the chapter on BiPath for information on how to use it.

                                     BiMenu

Kill Transfer List

This selection deletes the current transfer list file.

Select New Transfer List

This  selection invokes the program BiSelect so that you can pick a new transfer
list. When BiSelect terminates control will return to BiMenu. See the chapter on
BiSelect for information on how to use it.

Configure BiModem

This  selection  invokes the  program  BiConfig so  that you  can  establish the
operating environment for  BiModem and all  its support programs. When  BiConfig
terminates control  will  return to  BiMenu.  See the  chapter  on BiConfig  for
information on how to use it.

Exit

This selection terminates BiMenu. The Escape key also terminates BiMenu.

BiMark - An Easy way to mark uploads

BiMark is  a program designed to let you browse  through your system's files and
mark what files you want to send to another system. It is designed to be invoked
from BiMenu, but you can invoke it from the command line if you prefer.

The Command Format is:

     BiMark [/?] [/C Config_Path] [/P Transfer_List_Path]

/?

This displays the acceptable arguments.

/C Config_Path

Tells BiMark what  configuration path to use. The default is BiModem.cfg in your
current directory.

/P Transfer_List_Path

Tells BiMark what  transfer list path to  use. This argument overrides  the path
specified in the configuration file.


BiMark initially displays all  files and directories in your  current directory.
If  you have a list of sending directories,  then BiMark will start out with the
first directory in that list, instead  of the current directory. Directories are
listed  first  in  alphabetical  order.  Next  it  will  display  the  files  in
alphabetical order. When a directory is selected the screen will  be redisplayed
with the directories  and files in that  directory. The first directory  will be
the .. directory if  you are not in the  root. This is a special  directory that
allows  you to get back to the parent directory. To select a file to be sent you
must  position  the cursor  on  the file  and  press enter.  Selected  files are
highlighted. If you  want to cancel a selection, position the cursor on the file
and press enter.

BiList - An easy way to mark downloads

BiList is  a program designed to let you  browse through a previously downloaded
list  of files on another system,  and mark what files  you want to receive from
that system.  It is designed to  be invoked from  BiMenu, but you can  invoke it
from the command line if you prefer.

The Command Format is:

     BiList [/?] [/C Config_Path] [/P Transfer_List_Path]

/?

This displays the acceptable arguments.

/C Config_Path

This tells BiList what configuration path to use. The default is  BiModem.cfg in
your current directory.

/P Transfer_List_Path

This tells BiList  what transfer list path  to use. This argument  overrides the
path specified in the configuration file.

                                     BiList

BiList will  default to the file named in  your configuration file. See BiConfig
'Filenames and  Paths'. If that file  does not exist you will  see the following
screen.

This screen is an example of what might  be in a files.bbs file. The first  line
of the  display is the  path to the file  currently being displayed.  The second
through the  last lines are records in the file.  The arrows imbedded in the top
and bottom borders show the column where BiList will look for file names. In the
example the  only valid file  names are FILES.BBS  and BIMOD124.ZIP. The  cursor
will start out on the first valid file name of FILES.BBS. If this is a file that
you want downloaded then  press enter. BiList understands the  following formats
for file names.

     File.Ext
     File    .Ext

This moves  the column indicators 1 position to the right. If there are no valid
files  at  this column  location,  BiList will  continue to  advance  the column
indicators until it finds a valid file name. This also will cause the display to
move to the first page in the file that contains a valid file name.

files  at  this column  location,  BiList will  continue to  decline  the column
indicators until it finds a valid file name. This also will cause the display to
move to the first page in the file that contains a valid file name.

Tab

This moves the  column indicator  to the  next position divisible  by eight.  If
there are  no  valid files  at this  column location,  BiList  will continue  to
advance the column  indicator until it finds  a valid file name. This  also will
cause the display to  move to the first page  in the file that contains  a valid
file name.

Back Tab

This  moves the column  indicator to the  prior position divisible  by eight. If
there  are  no valid  files at  this  column location,  BiList will  continue to
decline the column indicator  until it finds a  valid file name. This also  will
cause the display to  move to the first page  in the file that contains  a valid
file name.

Down Arrow

This advances to the next valid file name.

Up Arrow

This takes you back to the prior valid file name.

Page Down

This advances you to the  next page in the file and the cursor  will stop on the
first valid file name on that page.

Page Up

This takes you  to the prior page  in the file and  the cursor will stop  on the
first valid file name on that page.

Alt/C

This lets you enter a new path to a different files listing. The cursor  will be
positioned on the file path on line 1. Then you can enter a new path name, enter
to retain the same name, or Esc to exit BiList.

BiHot - Another way to mark downloads

BiHot is a program  designed to let you mark files displayed  on your screen for
subsequent downloading. It is a hot key program. So you  must load it before you
display something to  be marked. Once loaded it will remain in memory monitoring
your keystrokes for Ctrl/M  and Ctrl/U. Ctrl/M causes it to enter  mark mode and
Ctrl/U causes it to  unload itself. If Ctrl/M or Ctrl/U  conflict with keys that
you  routinely use in another software package, you  may redefine them to be any
key sequence you want (See BiConfig 'Key Definitions').

The Command Format is:

     BiHot [/?] [/C Config_path] [/P Transfer_List_Path]

/?

This displays the acceptable arguments.

/C Config_Path

Tells BiHot  what configuration path to use. The  default is BiModem.cfg in your
current directory.

/P Transfer_List_Path

Tells BiHot  what transfer list  path to use.  This argument overrides  the path
specified in the configuration file.

                                      BiHot

The first time BiHot is loaded it will display the following message:

     BiHot - (C) Copyright Erik Labs, 1989,90

          Installed - Depress (Ctrl/M) to activate or (Ctrl/U) to unload

BiHot need only be loaded once. If you attempt  to load it a second time it will
display the following message:

     BiHot - (C) Copyright Erik Labs, 1989,90

     Already Loaded - Depress (Ctrl/M) to activate or (Ctrl/U) to unload

If you  enter Ctrl/U any  time after  loading BiHot it  will unload itself  from
memory. Ctrl/M is  used to enter  mark mode.  Here is a  sample screen that  you
might have displayed before entering Ctrl/M.

BiSelect will start  out by displaying any  transfer list files (*.PTH)  in your
current  directory. The  cursor will stop  on the  New field. This  field is for
typing in a new transfer list file name. If the transfer list is in  a different
directory, or does not  have a suffix of PTH,  you can hit Alt/C to enter  a new
search string. If the file exists  you can position the cursor to it  (using the
up and  down arrows or  the first letter  of the name)  and select it  using the
enter key.

You may use any of the following acceptable keys:

Down Arrow

This advances to the next transfer list file.

Up Arrow

This takes you back to the prior transfer list file.

Page Down

This advances you to the next page of transfer lists and the cursor will stop on
the first transfer list file on that page.

Page Up

This takes you to the  prior page of transfer lists and the cursor  will stop on
the first transfer list file on that page.

Alt/C

This lets you enter a new search string for the transfer lists. The cursor  will
be positioned on the  search string on line 1.  Then you can enter a  new search
string, enter to retain the same name, or Esc to exit BiSelect.

Esc

This exits BiSelect.

BiPath - The original transfer list maintainer

BiPath is a program  designed to let you maintain  the list of files to  be sent
and/or received. It is designed to be invoked from BiMenu, but you can invoke it
from the command line if you prefer.

The Command Format is:

     BiPath    [/?]
          [/C Config_Path]
          [/P Transfer List Path]

/?

This displays the acceptable arguments.

/C Config_Path

This tells BiPath what configuration path to  use. The default is BiModem.cfg in
your current directory.

/P Transfer List Path

Tells BiPath what  transfer list path to  use. This argument overrides  the path
specified in the  configuration file. If  you do not  pass this argument  BiPath
starts out with an empty file.

                                     BiPath

BiPath starts out by displaying all files currently selected to be sent/received
in  the  top  part   of  the  screen.   The  cursor  will   then  stop  on   the
(U)pload/(D)ownload  field  and  wait  for  you  to  enter  a  new  file  to  be
sent/received. If you want to modify an existing transfer request you  can press
PgUp and PgDn to get to the request you  want to modify. Then you may use Ctrl/D
to delete the request  or retype the information to change it.  Here is a sample
screen followed by a description of the fields, and a list of valid keys.

(U)pload/(D)ownload

This field will only accept  a U for upload or a D for  download. Upload means a
file that is going to be  sent from your computer to another computer.  Download
means  a file that  is going to  be received on  your computer,  sent by another
computer.

Source File

This field is the path to the source file(s). It can contain star names.  For an
upload it would point to one or more  files on YOUR computer. For a download  it
would point to  one or more files  on ANOTHER computer. If  it is an upload  the
path is checked to insure at least one file exists. Some bulletin boards may not
allow the use of full paths. If this is the case then the file part  of the path
you  have entered  will  be used  and the  path part  will  be ignored.  You can
configure  BiModem  to search  multiple directories  for  a file  (See BiConfig,
Filenames  and Paths). This will only work if  a simple name (file name only, no
path) is used  or, the  file name has  been stripped  from the path  due to  the
simple name  only configuration option.  You also can  supply a password  in the
source file like  this: [D:\path\]file,password. If  you are downloading a  file

                                       34




                                     BiPath

that is password protected, this is the only  way that you can get the file.  If
you are  uploading a file and  you supply a password, the  filename and password
are  added to  the remote's  password  file. This  means  that no  one else  can
download this file unless they know the password you have assigned to it.

Dest File

This field  is optional.  This instructs BiModem  where to put  the file  on the
receiving computer.  For an  upload this  would be  on ANOTHER  computer. For  a
download this would be on YOUR computer. If you omit this field the file will be
put in either  your current directory, or  the receiving directory  specified in
BiConfig. You  can point to  a directory by  terminating this field  in a slash.
This is extremely handy for star names source files.

Description

This field is optional. It is only meaningful for an upload. Some bulletin board
interfaces will use this field to post  the description of the file. If you omit
this field on an upload some bulletin board interfaces  will prompt you for them
after the transfer is completed.

Refresh

This field is optional. You may  specify a Y,N,or space. A Y indicates  that you
want the file verified via checksum and any discrepancies found, sent. Of course
this will only occur if a file is found on the receiving side. If the file can't
be found then BiModem  will perform a normal transfer. An N  has no effect other
than eliminating a default Y  in BiConfig. A blank in this field  indicates that
BiModem will use the BiConfig default for uploads or downloads.

Replace

This field is optional. You may specify  a Y,N,or space. A Y indicates that  the
file will be replaced (if the receiver  allows replacements). An N has no effect
other than eliminating a default Y in BiConfig. A blank in  this field indicates
that BiModem will use the BiConfig default for uploads or downloads.

Verify When Done

This field is optional. You may specify  a Y,N,or space. A Y indicates that  the
file will be verified when  the transfer is complete. An  N has no effect  other
than eliminating a default  Y in BiConfig. A blank in  this field indicates that
BiModem will use the BiConfig default for uploads or downloads.

Include Sub Directories

This field is not used at this  time. It is planned that a Y in  this field will
indicate  that  directories  subordinate to  the  one pointed  to  will  also be
searched for matching files to be transferred.

                                     BiPath

Delete SOURCE When Done

This field is optional. You may  specify a Y,N,or space. A Y indicates  that the
source file will  be deleted when a successful  transfer completes. This ability
can be  disabled via  BiConfig. An  N has  no effect  other  than eliminating  a
default Y in BiConfig. A blank in this field indicates that BiModem will use the
BiConfig default for uploads or downloads.

While using BiPath you may use the following list of acceptable keys.

Right Arrow

This advances the cursor 1 position to the right.

Left Arrow

This advances the cursor 1 position to the left.

Control Right Arrow

This advances the cursor 1 word to the right.

Control Left Arrow

This advances the cursor 1 word to the left.

Home

This puts the cursor at the beginning of the field.

End

This puts the cursor at the end of the field.

Control E

This deletes the current word.

Control U

This converts the case of the current letter.

Destructive Backspace

This deletes the character behind the  cursor and positions the cursor and  text
back 1 space.

Control I

This inserts 1 space at the current cursor position.

                                     BiPath

Del

This deletes 1 space at the current cursor position.

Control End

This erases from the current cursor position to the end of the field.

Alt E

This erases the entire field and puts the cursor in position 1 of the field.

Down Arrow

This advances to the next field.

Up Arrow

This takes you back to the prior field.

Control Home

This puts the cursor on the first field.

Page Down

This  accepts the  current transfer  request or  advances  to the  next transfer
request.

Control D

This deletes the current transfer request.

Page Up

This takes you back 1 transfer request.

Control Page Down

This advances you 1 page of transfer requests.

Control Page Up

This takes you back 1 page of transfer requests.

Alt/X

This exits BiPath and causes any modifications or additions you have  made to be
written to disk.

                                     BiPath

Esc

This  key has  many purposes.  Its  basic function  is  to undo  the last  thing
entered. For example if you were half way through entering a description and you
hit Esc,  it would  clear the  description field  and place  the  cursor at  the
beginning of the field. If you then hit Esc again it would clear the  record you
were working on and  position the cursor on the first field. Then if you hit Esc
again it would terminate BiPath and write the modifications to disk.

                                      BiBat


BiBat - The mini terminal emulator

BiBat's main purpose is to allow you to invoke BiModem on a bulletin board. Then
once it sees BiModem come  up it terminates so that BiModem can come  up on your
end.

BiBat  is  a mini  terminal  emulator  specially tailored  for  BiModem. Besides
performing ansi  graphics level terminal  emulation it also  monitors characters
received for 2  space/backspace pairs. The  space/backspace pair is how  BiModem
handshakes to determine that there  is a BiModem running on the  other end. When
BiBat  sees 2  space/backspace pairs it  terminates so  that BiModem can  be run
either through a batch  file or BiMenu. BiBat should not be run on both sides of
a connection, because it will never detect the 2 pairs of space/backspaces. Thus
it will never continue on to BiModem.

The Command Format is:

     BiBat [/C Config_Path]

/C Config_Path

Tells BiBat what configuration  path to use. The default is  BiModem.cfg in your
current directory.


Once invoked,  if Bibat does not immediately detect the 2 space/backspace pairs,
it displays the following message.

Dos to Comm Gateway -> Invoke BiModem on the other end
                       or press ESC to exit
(C) Copyright Erik Labs 1989,90

Then you may type characters and they will be passed to the comm port (Just like
any terminal emulator).  Normally you would  type whatever characters the  board
requires  to start  BiModem.  Characters received  from the  comm port  are then
displayed  on your terminal.  If it detects  the 2 space/backspace  pairs, BiBat
will terminate. You may also hit Esc to terminate BiBat. If BiBat is  terminated
with an escape it will return an  errorlevel other than 0. This allows BiMenu or
a .Bat  file to  react appropriately. BiMenu  will not  terminate in  this case.
Instead it will re-display its selection screen.

                                     BiModem


BiModem - The file transfer program

BiModem is the file  transfer program. It can be run all  by itself from command
line, or it can be invoked from  BiMenu. There are two references to BiModem  in
Bimenu.  Remote Bimodem  invokes BiBat  first and  then BiModem  (see  BiBat for
further info). The second invokes BiModem immediately.

The Command Format is:

     BiModem   [/?]
          [/A Abort Directory Path]
          [/B Baud Rate]
          [/C Config_Path]

          [/W Password File Path]
          [/> Old Format Intercommunications Log Path]

/?

This argument displays a list of acceptable arguments.

/A Sending Directory/List Path

This tells BiModem  what directory, or list  of directories, files will  be sent
from if  the user does  not specify a  path. It overrides  the sending directory
specified in the configuration file.

/B Baud Rate

This  tells BiModem  what baud  rate  to use  in its  time estimate.  This value
overrides the value specified in the configuration file.

/C Config_Path

This tells BiModem what configuration path to use. The default is BiModem.cfg in
your current directory.

                                     BiModem

/D File_List

This specifies a  list of files to  be acquired from the  remote computer. These
may be the simple  format or full paths. However, full paths  may not be allowed
on the remote computer.  It may strip away the  full path and only use  the file
name part of the path  specification. Due to limited  command line length it  is
not practical for more than a few file specifications. Note, that wildcard names
are permitted and that under certain circumstances many files may be transferred
with this  specification. If the file list  is preceded by an  @ (@download), it
indicates that this is  a path name to a c/r,l/f delimited list of file paths to
be downloaded. This list may contain files in the following format:

[D:\path\]file,password(C/R L/F)

This allows you  to access files that have  been password protected. Passwording
is not provided  for in command line  specifications. In other words  you cannot
say /D  file,password on  the command  line. This  is because  you can  separate
multiple file names with commas on the command line (/D file,file,file...).

/E Decimal Character Number to escape

This  tells  BiModem  what  character  that  you  want  escaped  (not  sent  but
translated).  Escaping can  decrease  performance  anywhere  from two  to  fifty
percent depending on  the number of escaped  characters in a file.  To eliminate
escaping you need to specify a /E0 argument. This indicates that you do not want
any characters escaped. If you omit this  argument, then BiModem will escape the
@ symbol. This is required for  PC pursuit connections. The remote BiModem  will
be informed  of your  desire to  escape a  character and,  if it  has an  escape
character of /E0 specified it will escape your character. It is recommended that
Bulletin  Boards  specify  a /E0  and  allow  the caller  to  specify  an escape
character if they are  calling over a network  that requires it. PC Pursuit  for
instance uses  an @  (or /E64)  symbol to stop  data flow  and enter  PC Pursuit
commands.

/F

This turns BiModem's DSZ receive logging off. Some bulletin board interfaces can
read a DSZ format log file, but they tend to get confused because there are both
uploads and downloads in the log. They usually do not maintain correct upload or
download statistics. By  using the  /F argument these  interfaces will  maintain
correct download statistics,  but not upload  statistics. This argument will  be
temporary  and it  will  go  away  when all  known  interfaces  properly  handle
BiDirectional DSZ logging.

/I New Format Intercommunications File Path

This tells  BiModem what  file to  use to  communicate between  BiModem and  BBS
interface programs. Without this argument BiModem will not generate this special
log file.

                                     BiModem

/J Rejection List Path

This tells BiModem the path to  a file containing a list of directories  to scan
to determine if  an incoming file should  be accepted or rejected.  It overrides
the file specified in the configuration file.

/L Comm Port

This tells BiModem  what communications port  to use. This  value overrides  the
value specified in the configuration file.

/N Sending Directory/List Path

This tells BiModem where files  will be sent from if the user does  not supply a
path.  Of  course if  you  are  disallowing  full paths  (see  BiConfig  general
options), then it would include all file requests. This can also be  the path to
a file containing a list of directories to be searched. This field overrides the
information in the configuration file.

/P Transfer List Path

This tells  BiModem  what transfer  list  path to  use.  It overrides  the  path
specified in the configuration file.

/Q

This tells BiModem to come up in quiet mode. Quiet mode is when BiModem does not
display anything. It is useful when invoking BiModem on a system that is running
some type of remote access software. It prevents the remote access software from
sending  changed screen information  out the comm port,  and destroying the data
being transferred.

/R Receiving Directory Path

This tells BiModem where to put files  that it receives. This argument overrides
the information stored in the configuration file.

/S Size Limit

This tells BiModem what size limit to  use. It overrides the value specified  in
the configuration file.

/T Time Limit

This  tells BiModem what  time limit in  minutes to use. It  overrides the value
specified in the configuration file.

                                     BiModem

/U File List

This specifies a  list of files to be sent to  the remote location. These may be
the simple  format, which requires that the file is  in the current directory or
one of  the directories specified in  the sending directory  list (see BiConfig,
Filenames and Paths), or  they may be full or partial paths.  Due to the limited
command  line  length,  it  is  a  convenient  way  to  send  a  very  few  file
specifications. Note, that  the wildcard specifications  are permitted and  that
depending on the situation, many files  may be transferred with this option.  If
the file list is preceded by an @  (@uploads), it indicates that this is a  path
name to  a c/r,l/f delimited list  of file paths  to be uploaded. This  list may
contain passworded files in the following format:

[D:\path\]file,password(C/R L/F)

This allows you to  upload files that  others can only access  if they know  the
password you have  assigned to it.  Passwording is not  provided for in  command
line  specifications. In  other words  you cannot  say /U  file,password on  the
command line.  This is because you can separate  multiple file names with commas
on the command line (/U file,file,file...).

/W Password file path

This tells  BiModem what password  file to use.  It overrides the  password file
identified in the configuration file.

/> New Format Intercommunications File Path

This tells  BiModem what  file to  use to  communicate between  BiModem and  BBS
interface programs. Without this argument BiModem will not generate this special
log file.

* version... Thank you for allowing me to download it.   Let me know if you  *
*----------------------------------------------------------------------------*
* Please, let us know what you think of BiModem.  It is our first Shareware  *
* product, and we really would like to make it the BEST PROTOCOL AVAILABLE.  *
* We feel that if a good percentage of people will call in with their        *
* comments (both good and bad), we will be able to reach this goal.  Thanks  *
* again for your interest in our product and keep in touch.                  *

The following  text describes  the information displayed  on BiModem's  transfer
screen. While you  probably will find most of the  information self explanatory,
you might want to read this section to be sure you understand it.

First, the top of the screen informs you who is on the other end. This option is
good for  sysops as they  may not have  been on  their system when  the transfer
began.

The second  section provides information  about the  file transfer  such as  the
names of files being transferred,  their length, and the rate at  which the data
is being transferred (Bytes Per Second). The first thing you will notice is that
the total Bytes Per Second (Located on the far right) doesn't appear to be equal
to  the sum of the bytes  per second on the  individual files. There are several
reasons for this. The reporting  is designed to be as accurate as  possible, and
the total fields  begin accumulation when BiModem  is started. If the  other end
waited several seconds to start up their end, it would severely reduce the total
throughput of the operation.  It also includes the identification  transfer that
identifies the user at the other end. This also reduces the total transfer rate.
The  figures  on each  file  represent  the  total  time and  actual  rates  for
transferring the files  that are sent. There  are 2 columns for  each file being
transferred. The first  column represents BiModem's  prediction of how long  the
transfer will take. The second column represents the real time transfer results.

                                     BiModem

The third  and perhaps the  most noticeable feature  of BiModem is that  you may
converse with the person  on the other end of the  connection while transferring
your files. Yes, it is just your normal chat window, but the good part  about it
is that it has no effect if it is not used. It also  has very little effect when
very fast typists use  the feature. We have  tested some very fast typists,  and
find that  even continuous  chatting during  the file  transfer will affect  the
transfer  throughput  only  3 to  10  BPS.  Only when  very  fast  key repeating
utilities are used does the effect become noticeable. As a little bonus, we have
allowed the ctrl-G keystroke to cause a beep at the other end.

Normally, BiModem will terminate  at both ends when all the  transfers, that you
requested,  have  taken   place.  However,  if  you  are  in  the  middle  of  a
conversation, it will go into  a mode called chat extension. During this mode it
will monitor chat activity and terminate when there has been  a 10 second period
of  silence. It also can  be terminated when  one end or the  other hits the ESC
key. Adding a  file during this mode is  not allowed, unless you  are talking to
another BiModem version 1.21 or greater. You will notice a change in  the screen
when this mode is active. Between the 2 chat windows you will see the following:

     -[Chat extended for 10 seconds. Esc to Terminate]-

The number of  seconds will decline in  this display, so  you can see where  you
stand. When the number  of seconds reaches 0, BiModem will  terminate. Each chat
character  you type, or  receive will  reset the  timer back to  10. So  if it's
getting  close to 0  seconds left, and  you want to  keep it going,  just type a
character.

The following lists the acceptable keys and what they do

Alt/A

This key is  applicable to the registered  version only. It allows  additions to
the transfer list. Brings up the following screen in the bottom chat window.

While this screen is displayed you may add a request. The keys  function similar
to  the way they do in BiPath.  Esc takes you out of  request add. Alt/X or PgDn
completes  the request.  None  of the  options are  overrideable  when adding  a
request  this way. The requests that you add will use the defaults from BiConfig
Upload and  Download defaults.  The meanings of  the fields are  the same  as in
BiPath, but we will reiterate them here.

                                     BiModem

(U)pload/(D)ownload

This field will only accept  a U for upload or a D for  download. Upload means a
file that  is going to be sent from your  computer to another computer. Download
means a  file that is  going to be  received on  your computer, sent  by another
computer.

Source File

This field is the  path to the source file(s). It can contain star names. For an
upload it would point to  one or more files on YOUR computer. For  a download it
would point to  one or more files on ANOTHER computer.  Some bulletin boards may
not allow the use of full paths.  If this is the case then the file  part of the
path you have entered  will be used and the  path part will be ignored.  You can
configure  BiModem  to search  multiple directories  for  a file  (See BiConfig,
Filenames and  Paths). This will only work if a  simple name (file name only, no
path) is used  or, the  file name has  been stripped  from the path  due to  the
simple name only configuration option.

Dest File

This  field is  optional. This instructs  BiModem where  to put the  file on the
receiving computer.  For an  upload this  would be  on ANOTHER  computer. For  a
download this would be on YOUR computer. If you omit this field the file will be
put in  either your current  directory, or the receiving  directory specified in
BiConfig. You can  point to a directory  by terminating this  field in a  slash.
This is extremely handy for star names source files.

Description

This field is optional. It is only meaningful for an upload. Some bulletin board
interfaces will use this field to post  the description of the file. If you omit
this  field on an upload some bulletin board interfaces will prompt you for them
after the transfers are completed.

Alt/S

This key is applicable to the registered version only. It allows you to kill the
currently transferring send file. It doesn't stop transferring until all buffers
are cleared. This usually  means it waits until up to 2 blocks of data have been
sent. If you are talking to a version of BiModem prior to 1.09 it will work, but
it just signals end of file.

Alt/R-Kill Receive

This key is applicable to the registered version only. It allows you to kill the
currently transferring receive file.  It will only work if you  are talking to a
version of BiModem  1.09 or better. It  happens immediately and doesn't  have to
wait for buffers to clear.

                                     BiModem

Alt/Q-Quiet Mode Toggle

This key  switches  between quiet  mode and  regular mode.  Quiet  mode is  when
BiModem does not display anything on the screen. You will notice a change to the
line between the two chat windows when you are in quiet mode. The following will
appear:

     -[Quiet Mode]-

Control G - Operator Page

This key rings the bell on  the remotely connected computer. Provided of  course
that the  remote computer  allows bells during  this time  of day  (See BiConfig
General Options).

Esc-Terminate

This key halts transmission, and terminates BiModem.

BiConfig - Configuring your environment

BiConfig is  a program  designed to let  you configure  BiModem and  its support
programs. It is designed to be invoked  from BiMenu, but you can invoke it  from
the command line if you prefer.

The Command Format is:

     BiConfig [/?] [/C Config_path]

/?

This argument displays a list of acceptable arguments.

/C Config_Path

Tells BiConfig  what configuration path  to use.  The default is  BiModem.cfg in
your current directory. If a configuration file is not found BiModem and all its
support programs will  default to  comm1 and  the same settings  it was  shipped
with.  So if  you  get yourself  into  trouble rename  the  BiModem.Cfg file  to
something else so the programs can use their "factory" settings.

Remove Snow

On some  older CGA display  adapters direct  screen writers will  cause flicker.
This field instructs  BiModem and its  support programs  to wait until  vertical
retrace happens before  moving things to the  screen. In layman's terms  if your
screen flickers say Y.

                                    BiConfig

Use Bios for Screen Display

BiModem and  its support programs  display approximately 100 times  faster if it
can talk  directly to your display hardware. So  whenever possible you want this
field to say N. Multi-tasking software such as Double Dos, Desqview, etc. do not
like programs to do this. The display is not stoppable and will bleed through to
the other  task(s). Another class  of programs  that doesn't like  direct screen
writers are the  ones that allow you  to remotely access  your PC. In order  for
them to see  what is displayed, the programs that you  run must use Bios. If you
are running one of these  types of programs you will want to say  Y to Use Bios.
(Note: BiModem itself will properly handle Double  Dos and is Desqview aware, so
normally you can  leave this set to N. The support  programs are Desqview aware,
but not Double Dos aware.)

Changing Colors

There are nine  different colors used in  BiModem and its support  programs. One
for  each  of  the  following  field  types: Prompts,  Fields,  Chat  characters
received, Chat characters typed, Menu item current and not marked, Menu item not
current  and not marked, Menu item current and marked, Menu item not current but
marked, and  error color. To  change one of these  colors you do  the following.
First position  the cursor to the appropriate  field type. Then you  can use the
right arrow and  left arrow to change  the foreground colors. The  control right
arrow and control left arrow keys will change  the background colors. There is a
sample BiModem screen displayed that will change colors as you change the colors
of the different field types.

Baud rate

This  field identifies  the  normal  connection default.  It  is  used only  for
computing estimated times and is overrideable by the /B option of BiModem. Since
BiModem  relies  on other  software  to  configure the  communications  port and
establish the modem connection,  there is no way  for it to know  the connection
rate.  If you  have  a MNP  modem  there is  no  accurate method  of  predicting
estimated times because of unknown compression factors.

Communications Port

This  field identifies the communications port number. It is overrideable by the
/L  option of BiModem. It is used as an index into the table defined in the Comm
Port Setup function of BiConfig.

Modem Type

This field identifies the type of modem that is used. F indicates that the modem
is full  duplex always.  This is  true of known  2400 baud  or less  modems, V32
modems, and  V42 modems. H indicates  that the modem  is full duplex  below 9600
baud and half duplex  above. This is true of US Robotics  HST modems, Hayes 9600
baud V29 modems, and most 9600 baud modems that  do not say they are V32 or V42.
D indicates that the modem  is full duplex if it connects to another  D or F and
half duplex if it  connects to another H. This  is true of the US  Robotics Dual
Standard.  If it connects  to another Dual  Standard Modem it  can transfer full
duplex,  but  if  it connects  to  a  HST it  talks  half  duplex. When  BiModem
determines that it must operate in half  duplex mode it will only send files  in
one direction at a time.  It will still allow chat.  Most half duplex modems  do
have  a slower  speed  back channel  that allows  chatting to  occur, but  if we
attempt to transfer  files bi-directionally the  modems usually thrash too  much
trying to contend for the fast side of the transmission.

CTS/RTS

This field indicates  whether you want  to use CTS/RTS  flow control. This  is a
requirement  for MNP compression/bit stripping  to occur. Under  MNP you need to
connect your PC to your  modem at a faster rate than the  modem is communicating
over the phone  line. This gives MNP time  to compress the data  and strip bits.
Likewise  on the  receive  side it  needs  to deliver  more  characters to  your
computer than it receives. Since you are talking to your modem faster than it is
sending  or receiving, there needs  to be some method  of throttling the data so
that you don't  overrun its buffer. The most efficient method available today is
CTS/RTS. It does  not require  any significant time.  The other method  commonly
used is Xon/Xoff. We have  elected not to use this method because  it slows down
transmission. The transmitting of Xon/Xoff characters  take time, not to mention
Xon/Xoff characters that occur  in data then have  to be escaped. In summary  if
your computer is talking to your modem faster than the modem is talking over the
phone line than you want to say Y to CTS/RTS.

Signal Loss of carrier on Carrier Detect

This field indicates  whether to  base carrier  loss on  a drop  of the  carrier
detect line from the  modem. Y indicates that if  the carrier detect line  drops
loss of carrier has occurred and BiModem terminates. Normally when someone hangs
up their modem, the other modem will no longer hear  the carrier signal and drop
the carrier detect line. Yet, some modems have been found that do not raise  the
carrier detect  line and causes  a loss of  carrier immediately. If  this occurs
change this value to a N.

Signal Loss of carrier on Data Set Ready

This field  indicates whether to  base carrier loss  on a  drop of the  data set
ready line. Y indicates  that if the data set ready line  drops, loss of carrier
has occurred and BiModem terminates. Normally  you would set this to N and  data
set ready will not be  tested. If you can't use Carrier Detect,  as mentioned in
the prior field, you may want to use data set ready.

Allow current directory access

This field  indicates whether  remote users  are allowed  access to  the current
directory. It is applicable to files sent from your system, only  if the sending
directory field  (see filenames and  paths) points to  a list of  directories. Y
indicates that it will first  search the current directory and then  the list. N
indicates that it will only search the list of directories.

Allow file names only

This field indicates  whether paths are  allowed on file  requests. Y  indicates
that other people can  NOT supply path names.  This does not say that  YOU can't
supply  paths.  Requests  that  are  generated  locally can  still  supply  full
pathnames to files.  Yet, if another computer supplies a full path the directory
part will be stripped away and just the file name will be used. N indicates that
other people CAN supply full path names.

Rename the file if it already exists

This field  determines if files  that already exist at  the destination location
are allowed  to be  replaced or  is the  new file  renamed to a  unique name.  Y
indicates that  a duplicate  file name  can NOT  replace the  dupe.  It will  be
renamed to a  unique name. This does  not prevent file recovery.  See "directory
that aborted files will be renamed into" under filenames and paths.  N indicates
that replacement of files is allowed.

Always verify when done

This field  determines if  files are  always verified  when the  transmission is
complete or  not.  Y indicates  that  whenever a  file  completes it  is  always
verified. N  indicates that verification  occurs only if requested  by the other
computer, the request, or because of a file sum error.

Do NOT allow source deletion

This  field indicates whether  source files can be  deleted when transmission is
complete. Y indicates that  files can never be deleted. N indicates  that a file
on your computer can be deleted after a successful transfer.

Retain original file date

This field indicates whether files you receive are to retain their original date
or get current date/time  stamped. Y indicates  that files received will  retain
their original date  and time. N indicates that files received will be date/time
stamped according to the clock.

Do NOT allow full directory transfers

This field is not currently used. Its future intent  is to disallow the transfer
of a  directory and  all its  sub directories by  pointing to  the directory  in
question.

Do NOT allow sub directory transfers

This field is  not currently used. Its future intent is  to disallow the include
all sub directories type of transfer.

Replace Timer Interrupt

This field indicates whether to replace the timer interrupt. On a few systems we
have encountered problems  in the timer interrupt bios. On these systems BiModem
gets  many  Naks. Generally  the interrupt  replacement  is not  necessary. When
running under multi-tasking software such as Double Dos and Desqview replacement
of  the timer  interrupt  can cause  problems.  Local  Area Networks  also  have
problems if  the  timer interrupt  is  replaced. So  we  normally recommend  not
replacing it unless you absolutely have to. Y indicates that the timer interrupt
is replaced by a small  and quick version. N indicates that  the timer interrupt
is not replaced.

Replace Keyboard Interrupt

This field indicates whether to replace the keyboard interrupt. On a few systems
we have encountered problems  in the keyboard  interrupt bios. On these  systems
BiModem gets  many Naks while chatting. When not chatting files transfer without
errors. Generally the interrupt replacement is not necessary. When running under
multi-tasking  software  such as  Double  Dos  and Desqview  replacement  of the
keyboard interrupt can cause problems. Local Area Networks also have problems if
the keyboard interrupt  is replaced. So  we normally recommend not  replacing it
unless you absolutely have to. Y indicates that the timer interrupt is replaced.
N indicates that the keyboard interrupt is not replaced.

Allow remote file requests

This  field  indicates  whether remote  transfer  requests  will  be allowed.  Y
indicates  that  other  people  may request  that  files  be  sent to/from  your
computer. N indicates that  any file requests received from the  remote end will
be rejected. The message  "Rem Req Disallowed" will be displayed on both ends if
a file is remotely requested  and you do not allow it. If the  remote end is not
at least version  1.13 it will  receive either the  message "File Not  Found" or
"Create/Open  Error"  instead.  Some  bulletin   board  interface  writers  have
requested this  option so that they may  require file requests to  be entered on
the  BBS. We hope this  does not become  a standard interface  design because it
does  not allow  you  to use  BiHot,  BiMark, BiList,  and  online file  request
additions. However, some kind of BBS interface is preferable to none at all.

Allow local file requests

This  field  indicates  whether  local  transfer  requests will  be  allowed.  Y
indicates  that  local transfer  requests are  allowed.  N indicates  that local
transfer requests  are not allowed. No messages  are displayed. It just bypasses
loading the paths  file and/or  any /u,/d  arguments. This is  provided so  that
BBS's can prevent people from uploading  a bimodem.pth and having access to  all
files on their  systems. Of course, if  properly configured, the user  would not
normally have access to the directory where  bimodem.pth lives. We are providing
this option just to insure security.

Skip transfer if same date/time/size

This field  indicates whether files  that have the  same date and time  and size
will be skipped. Y  indicates that if you are attempting to  receive a file that
has the same date and time and size as one that already exists in your receiving
directory, it will be skipped. N indicates that in this situation the file would
be verified.

start and stop time are zero then paging can be done any time.

Phone number edit mask

This field defines how phone numbers will be displayed. Phone numbers are always
stored as 10 digit numbers. How these 10 digits are edited is up to you. This is
done via a mask. In  the mask where ever the digit 9 occurs  it will be replaced
by 1 digit  from the phone number. When entering a  new mask make sure there are
10 9's in the mask or the results may be a program crash. The default US mask is
supplied [phone]. An  example of  one of the  European masks is  +999-999-
9999. This mask is only used when talking to a BiModem version 1.20 or below.

Directory that files will be received into

This field identifies the directory that files without paths are to  be received
into.  This would include all files if you  have specified that you allow simple
names only (see general options).

Directory that aborted files will be renamed into

This field  identifies the directory  that aborted  files will be  renamed into.
This is  only pertinent to files  being received. Aborted refers to  any type of
abortion ie.  user cancel, carrier  loss, user hitting  the esc key.  The rename
will fail unless the directory is on the same drive as the  receiving directory.
BiModem will not copy  a file to  another drive. Every time  a user attempts  to
send you a  file, this directory will be checked first  to decide if the user is
attempting to recover from a prior abortion. If the file they are trying to send
to  you exists  in this  directory  it will  be  renamed back  to the  receiving
directory and the transmission will restart where it left off.

Delete aborted destination files

This field indicates that an aborted  file should be deleted. Aborted refers  to
any type of  abortion ie. user cancel, carrier  loss, user hitting the  Esc key.
This only applies to files being received.

List of directories that determine rejections

This field  identifies a file that contains  a list of directories  that will be
scanned to figure out  if you already have the  file the user is trying  to send
you. If the file is found in  any of these directories, then the transmission is
halted.  If the  user  has a  version  prior to  1.10  than it  will  be sent  a
create/open error.  If the user has  1.10 or above then  it will be  sent a file
rejected error. The directories  in the list should be  terminated by a \ and  a
carriage return and line feed. If you press F2, BiConfig will read this file and
allow you to modify it.

Directory or list of directories files are sent from

This field identifies where files will be sent from if the user does not  supply
a path. Of course if you are  disallowing full paths (see general options), then
it  would  include all  file  requests. This  field  also can  point  to  a file
containing a list  of directories to  be searched. The  directories in the  file
should  be terminated by  a \, carriage return,  and line feed.  For a star name
request all the  directories in the list  will be searched. For a  non star name
request when the first  match is found directory searching will  terminate. If a
list  of directories  is supplied, then  the current directory  is checked first
followed by  the first directory in  the list. Unless you have  specified no cur
dir, then it will  start out with the first  directory in the list and  not even
touch the current directory. If this field points to a list of  directories, you
may press F2 to have BiConfig read the list and allow you to modify it.

Path to Password file

This field  identifies the path of the  password file. Passwords can  be used to
make certain files  accessible only if you  know the correct password.  The file
that this path points to can contain up to 500 entries in the following format:

FilePath,Password(C/R L/F)

If the FilePath is  a simple file name it  applies to all files by that  name in
all your directories. If,  on the other hand, the FilePath is a full pathname it
is  applicable only to  that one file.  It is recommended  the absolute paths be
specified, not relative (no ..\dir\file). This  is because the paths must  match
exactly.  The filename  part  of the  path  may contain  *  names. When  someone
requests a file that is password protected they must supply the password as part
of the  pathname  ([d:\path\]file,password).  You may  also  upload  a  password
protected file to someone. This is done by supplying the password as part of the
source pathname ([d:\path\]file,password). BiModem will  recognize that you have
uploaded  a  password protected  file when  it  terminates and  write out  a new
password file. Then the  next person that tries to  download that file can  only

download it if they  know the password. If  you hit F2, BiConfig will  read this
file and allow you to modify it.

Path to Upload/Download list file

This field identifies the default transfer list path. The file it points to need
not exist as BiModem and its support programs will create it when needed.

Path to default files list for BiList

This field identifies  the default  path to  the files list  that BiList  should
start out with.

Path to log file

This field  identifies the file that logging information  will be written to. If
the file exists the logging info  will be appended to the end, otherwise  a file
will be created. What  information is logged to  this file is controlled by  the
following 2 fields. Please make sure that this  log file is not the same as  the
DSZ log and the intercom log (See BiModem) or DOS will get confused.

Are connects/disconnects to be logged

This field determines  if connections and disconnections are to be logged to the
file identified in the path to log file field. Y indicates that connections  and
disconnections are to be logged. N indicates that they are not logged.

Are file transfer statistics to be logged

This field  determines if file transfer statistics are to  be logged to the file
identified in  the  path to  log  file field.  Y  indicates that  file  transfer
statistics are to be logged. N indicates that they are not logged.

Appendix A - Logging

BiModem optionally  uses 3  different logging  methods and  formats. We  provide
these many different methods so that interfacing BiModem to Bulletin Boards  and
Terminal programs  is as  easy  as possible.  Please  consult your  terminal  or
interface documentation to determine the type of logging it requires (if any).

The  user log  defined  by BiConfig  is  a  general purpose  log.  It is  easily
displayable by many  utilities including edlin and  copying it to con.  You have
complete  control of  the level  of logging (full,transfer  only, or  none), and
where to put the file.  This is set using BiConfig. Several  interfaces use this
log because of its ease of viewing.

What  we call  an  intercommunications log  is available  by passing  BiModem or
BiMenu a  \^P Log_Path argument. The file that this creates is very difficult to
view. However, it  is considerably  easier to deal  with programmatically.  When
writing  an interface program  we recommend using  this log. It  is the only log
that  contains the  descriptions. All  the data  fields in  it are in  hex. Each
record in  it is a  fixed length. All interfaces  written by Erik  Labs will use
this log, because it is so easy to deal with.

The  third log file  we call  our DSZ  log. It is  in the  same format  that the
original Zmodem(tm) DSZ program outputs. Since there are already many interfaces
available for DSZ this  makes the interfacing job considerably  easier. However,
we must caution you  that most of the existing DSZ log  interfaces do not expect
bi-directional activity. As a  temporary measure to  solve this problem we  have
provided a  /F argument to  BiMenu and BiModem.  When this argument  is present,
only files that are  sent are logged.  This insures that  at least the  download
statistics are correct. To  use the DSZ log, simply execute  a "SET DSZLOG=path"
command prior to invoking BiModem or BiMenu.

Appendix C - Interfacing & Installation

Setup for most telecommunications programs is easy. In this  appendix we attempt
to walk you  through the detailed process of  setting up BiModem to  be executed
from some more  common telecommunications  programs. We apologize  if we  missed
your telecommunications  program. There are  far to many  of them to  cover them
all. Most of these programs allow a jump to dos and this is probably the easiest
way to initially test  BiModem. After signing in to your  favorite BBS, when you
get  to the  point you  are ready to  transmit files,  you can  jump to  DOS and
execute BiMenu. From there  you can use one of  the many ways to mark  files for
download/upload, or use transfer list maintenance to enter the list of files you
want to  send/receive. When you  have all the  requests entered, you  can select
remote BiModem. This allows you to tell the board you are ready to run  BiModem.
When  the BBS  loads  BiModem, remote  BiModem  will recognize  that fact,  load
BiModem  on  your end,  and  start  transferring  files. When  the  transfer  is
complete,  you  will be  back  at  DOS,  and you  can  type  exit  to return  to
telecommunications program. The following  discussions will instruct you  on how
to hook  BiModem up to your  communications program, and  avoid the jump  to dos
step.

The Telix connection

There are 2 main methods of connecting BiModem to Telix. It can  be connected as
an external protocol,  or as  a hot key.  Since Telix  is not set  up to  handle
BiDirectional file transfers through the external protocol option, the preferred
method is to set it up as a  hot key. We also will describe how to set it  up as
an external protocol, just in case you prefer that method.

Hot Key Setup

Telix allows  any key (or combination of  keys) to be setup to  execute a script
file. We provide you with a script file that executes BiMenu called BiModem.SLT.
If you run  the install program  (BInstall), then it  is copied into  your telix
script directory. Follow these simple instructions to tell Telix about it.

     1. Invoke Telix.
     2. Hit Alt/K to bring up the keyboard definitions screen.
     3. Select Regular.
     4. Select Edit.
     5. Type the key you wish to become the hot key. We recommend control B.
     6. Type in @BiModem. This tells Telix to run the script BiModem.SLT
     7. Press the space bar to exit.
     8. Select Save.
     9. Hit Enter to save it to telix.key.
     10. Select eXit.

Now to bring up BiMenu all you have to do is hit Ctrl/B.

Sample Telix Script File (Included as BiModem.SLT)

main()
{

                                       79




                                   Appendix C

dos("BiMenu",0);
}

This script will, of  course, have to be compiled prior to use with Telix. It is
written for Telix 3.10.  Therefore, it may differ with other  releases of Telix.
To compile the script type:

CS BIMODEM

External Protocol Setup

Up to 4 external protocols can be set up in Telix. You can set up  BiModem as an
external  protocol and have  it act just  like all the  internal protocols. This
includes having Telix ask you for the files to upload OR download. Unfortunately
telix was  not written with  bidirectional transfers in  mind, so setting  it up
this way  limits BiModem to one  direction at a time  (Like all the  rest of the
protocols). You may want to set up this method so you can use BiModem quickly on
those occasions  when you only have  1 direction to  transfer. To set it  up you
must first create 2 batch files. These batch files will be executed whenever you
select B from PgUp/PgDn of Telix.
The first batch file should be called bimodemu.bat and look like this:

     BiModem /B %1 /L %2 /U %3

The second batch file should be called bimodemd.bat and look like this:

     BiModem /B %1 /L %2 /D %3

The next thing you must do is enter telix and follow these simple instructions:

     1. Select ALT/O to configure Telix.
     2. Select Protocol options.
     3. Type B to enter BiModem as external protocol B.
     4. Type B to make B the key to select BiModem from PgUp/PgDn.
     5. Type BiModem as the protocol name.
     6. Type BiModemU as the Upload Filename.
     7. Type BiModemD as the Download Filename.
     8. Select Batch-file.
     9. Select Yes for "prompt for the name on downloads"
     10. You are done, make sure you select "Write setup to disk".

Note: Some people prefer  to set up BiMenu in their batch files. While this does
give  a uniform  method of  selecting  transfer protocols,  there is  no  way to
prevent Telix from prompting  for file names on uploads. To  avoid this unneeded
step we prefer the Hot Key Setup method.

                                   Appendix C

The Boyan connection

Boyan can  be set up  2 different ways,  as an external  protocol or a  hot key.
Since Boyan  is not  set up to  handle bidirectional  transfers in  its external
protocols, so we recommend the hot key method. We will describe both methods, in
case you want to use BiModem unidirectionally.

Hot Key Setup

Boyan allows most keys (or combination  of keys) to be setup to execute  a macro
command. However, they  have certain  pre-defined functions that  occur on  some
keys. My favorite, Alt/B,  is used to turn beeps  on and off. If you  don't need
this function, go  ahead and use that  key sequence. We will,  however, describe
how to hook BiMenu up to Alt/1.  Follow these simple instructions to tell  Boyan
about it.

     1. Invoke Boyan.
     2. Hit Alt/C to bring up the configuration screen.
     3. Type M to select macros.
     4. Type G to bring up the key set including Alt/1.
     5. Type 61 to select Alt/1.
     6. Type the macro: \DC-[BiMenu].
     7. You are done. Hit multiple escapes to return to the main screen.

Now to bring up BiMenu all you have to do is hit Alt/1.

External Protocol Setup

Up to 10 external protocols can be set up in Boyan. You can set up BiModem as an
external protocol  and have it  act just like  all the internal  protocols. This
includes having Boyan ask you for the file to upload OR  download. Unfortunately
Boyan was not  written with bidirectional  transfers in mind,  so setting it  up
this  way limits BiModem to  one direction at  a time (Like all  the rest of the
protocols). You may want to set up this method so you can use BiModem quickly on
those occasions when you only have 1 direction to transfer. The  first thing you
must do is enter Boyan and follow these simple instructions:

     1. Select ALT/C to configure Boyan.
     2. Select X for external protocols.
     3. Select an available protocol # (0-9).
     4. Type BiModem as the protocol name.
     5.  Type B as the menu letter. Some  systems may us B for Compu-Serve, then
choose I.
     6. Type BiModem.Com as the External File.
     7. Hit Enter for No Prompt for DL-Name.
     8. At the BiModem Upload Prompt type:
        \DC-[%P:BiModem /L %MD /B %MS /U %TF].
     9. At the BiModem Download Prompt type:
        \DC-[%P:BiModem /L %MD /B %MS].
     10. You are done. Hit multiple escapes to get back to the main screen.

                                   Appendix C

The Procomm connection

Procomm can be set up 3 different ways, as an external protocol, a hot key, or a
script file.  The script file  method requires  you to type  in the name  of the
script,  after  alt/f5,  each time  you  run  one. Since  that  is  far  to many
keystrokes  to do something  as common  as a file  transfer protocol, we  do not
recommend  this  method.  However,  we  do   supply  an  example  script  called
BiModem.ASP, just in case.  Since Procomm is not set up  to handle bidirectional
transfers  in its external protocols, so we suggest  the hot key method. We will
describe both methods, in case you want to use BiModem unidirectionally.

Hot Key Setup

Procomm  allows two user hot keys to be  defined to execute a program (Alt/J and
Alt/U). Procomm allows programs  to be executed  when you hit  one of these  two
keys. Follow these simple instructions to tell  Procomm what to do when an Alt/J
or Alt/U is hit.

     1. Invoke Procomm.
     2. Hit Alt/S to bring up the setup screen.
     3. Select file/path options.
     4. Select either F for Alt/J or G for Alt/U.
     5. Type BiMenu.
     6. Hit Escape.
     7. Your done, Select Save Setup Options.

Now to bring up BiMenu all you have to do is hit Alt/J or Alt/U.

Sample Procomm Plus Aspect File (Included as BiModem.ASP)

DOS "BiMenu.Com"

This  script needs to be  copied to your Procomm Plus  directory. It is executed
while connected  to your  remote site (Usually  a BBS), by  pressing alt  F5 and
entering BIMODEM in the window.

External Protocol Setup

Only 3 external protocols can be set up in Procomm. You can set up BiModem as an
external  protocol and have  it act just  like all the  internal protocols. This
includes  having  Procomm  ask  you  for  the  files   to  upload  OR  download.
Unfortunately Procomm was not  written with bidirectional transfers in  mind, so
setting it up this way limits BiModem to  one direction at a time (Like all  the
rest of the  protocols). You  may want  to set  up this  method so  you can  use
BiModem quickly on those occasions when  you only have 1 direction to  transfer.
To  set it up  you must first  create 2 batch  files. These batch  files will be
executed whenever you select 14-16 from PgUp/PgDn of Procomm.

The first batch file should be called bimodemu.bat and look like this:

     BiModem /U %1


                                       83




                                   Appendix C

The second batch file should be called bimodemd.bat and look like this:

     BiModem /D %1

The  next  thing  you  must  do  is   enter  Procomm  and  follow  these  simple
instructions:

     1. Select ALT/S to configure Procomm.
     2. Select Protocol options.
     3. Type A, C, or E to enter BiModem as external protocol 1, 2, or 3.
     4. Type BiModemU as the upload filename.
     5. Type B, D, or F to enter BiModem as external protocol 1, 2, or 3.
     6. Type BiModemD as the download filename.
     7. Hit Esc to exit.
     8. You are done, make sure you select "Save Setup Options".

Note: Some  people prefer to set up BiMenu in their batch files. While this does
give a  uniform  method of  selecting transfer  protocols, there  is  no way  to
prevent Procomm from prompting for file names on uploads or downloads.  To avoid
this unneeded step we prefer the Hot Key Setup method.

The Qmodem connection

Qmodem can be set up 3 different ways, as  an external protocol, a hot key, or a
script file.  The script file  method requires  you to type  in the name  of the
script, after alt/f, each time you run one. Since that is far to many keystrokes
to do something as common as a file transfer protocol, we do not recommend  this
method. However,  we do  supply an  example script  called BiModem.SCR,  just in
case.  Since  Qmodem is  not set  up  to handle  bidirectional transfers  in its
external  protocols, so  we suggest the  hot key  method. We will  describe both
methods, in case you want to use BiModem unidirectionally.

Hot Key Setup

Qmodem allows function keys to be defined to execute a program or script. Follow
these simple instructions to tell Qmodem what to do when F1 is hit.

     1. Invoke Qmodem.
     2. Hit Alt/J to define function keys.
     3. Type 1 for normal function keys.
     4. Type @shellx BiMenu
     5. Hit F10 to save the new function key definition.
     6. Hit Escape. You're done.

Now to bring up BiMenu all you have to do is hit F1.

Sample Qmodem Script File (Included as BiModem.SCR)

DOS "BiMenu.Com"
EXIT

This script needs to be copied to your Qmodem directory.
This is admittedly  a very simple script  file, but it is intended  mostly as an
aid to understanding what is required.  Secondly, for the novice programmer  who
may not know where to begin with a script file, this may lend some assistance.

External Protocol Setup

Up to 10 external protocols  can be set up in Qmodem. You can  set up BiModem as
an external protocol and have  it act just like all the internal protocols. This
includes  having  Qmodem   ask  you  for  the  files  to   upload  OR  download.
Unfortunately Qmodem was  not written with  bidirectional transfers in mind,  so
setting it up  this way limits BiModem to one direction  at a time (Like all the
rest of  the protocols).  You may  want to  set up  this method so  you can  use
BiModem quickly on those  occasions when you only have 1  direction to transfer.
To set  it up you  must first create  2 batch files.  These batch files  will be
executed whenever you select B from PgUp/PgDn of Qmodem.

The first batch file should be called bimodemu.bat and look like this:

     BiModem /B %1 /L %2 /U %3

The second batch file should be called bimodemd.bat and look like this:

                                       85




                                   Appendix C


     BiModem /B %1 /L %2

The next thing you must do is enter Qmodem and follow these simple instructions:

     1. Select ALT/N to configure Procomm.
     2. Type P for Protocols.
     3. Type 0 to enter BiModem as an external protocol.
     4. Type S to enter the selection character.
     5. Type B to have B be the selection character.
     6. Type P to enter the protocol name.
     7. Type BiModem as the protocol name.
     8. Type U to enter the upload bat file name.
     9. Type BiModemU so it will execute BiModemU.Bat on PgUp.
     10. Type D to enter the download bat file name.
     11. Type BiModemD so it will execute BiModemD.Bat on PgDn.
     12. Type F to enter the file name prompt option.
     13. Type N to indicate no file name prompt on downloads.
     14. Hit Esc twice to return to the setup screen.
     15. Type E to exit.
     16. Type S to save.

Note: Some people prefer to set up BiMenu in their batch files.  While this does
give a  uniform  method of  selecting transfer  protocols, there  is  no way  to
prevent Qmodem from prompting for file names on uploads. To avoid  this unneeded
step we prefer the Hot Key Setup method.

BiHot problems with Qmodem

Many  people have reported  a problem running BiHot  in conjunction with Qmodem.
Qmodem has the ability  to take over the  keyboard interrupt. When this is  done
BiHot, who is also hooked to the keyboard interrupt,  never sees its key struck.
There is a simple solution. The following describes in detail how to make Qmodem
not take over the keyboard interrupt.

     1. Invoke Qmodem.
     2. Hit Alt/N to bring up the setup menu.
     3. Select O for Options.
     4. Select R for Runtime Parms.
     5. Insure that Int16 Enable is Off.
     6. Make sure you save your changes when you Exit the Setup Menu.

The GT Powercomm connection

GT  Powercomm (or  GT  for short)  was the  first telecommunications  package to
integrate and ship BiModem with itself. It is a very good communications package
that integrates terminal  emulation, BBS, and  mail functions into one  package.
BiModem is simple to install in GT. Just follow these simple procedures:

     1. Install BiModem into a directory subordinate to GT's main directory
        called BiMod. (See the installation chapter at the front of this
        manual for more info).
     2. Make sure that the files protocol.bbs and protocol.cbs allow for the
        protocol i.

That's all  it takes. You're  ready to use  BiModem in terminal, host,  and mail
mode. GT uses two files in the main GT directory that control BiModem execution.
On our GT  installation I have slightly modified  them so that I  can use BiMenu
when I'm in  terminal mode. They  are called BiRx.Bat  and BiTx.Bat. Both  files
should be identical. Here is the file that I run:

rem   Batch file for BIMODEM
rem
f:\gt\gtbimod %1 %2 f:\gt\bimod\
if errorlevel 4 goto mail
if errorlevel 3 goto host
if errorlevel 2 goto term
goto end
:term
f:\gt\bimod\bimenu /c f:\gt\bimod\bimodem.cfg /p f:\gt\bimod\bimodem.pth
goto end

BBS Installation

In order  to run BiModem  on your Bulletin Board,  it will require  an interface
program.  Current bulletin board  software was  not designed  with BiDirectional
transfers in mind. To  date none of them will  allow a user to type  both upload
files and download files before indicating the transfer protocol to use. Ideally
they would ask for the protocol first so that they would know whether to ask for
only one side  or both, and then  ask for the files  to send and/or receive.  Or
perhaps  they should  have  a  separate  entry in  their  files  section  called
BiDirectional transfer that the user could select instead of upload or download.
Of course that's  just the surface  of the problem. None  of them will  properly
handle user statistics, and directory list  maintenance when files are both sent
and received  at the same  time. So what's  the solution?  Well until the  board
authors redesign their boards to handle BiDirectional transfers, the only answer
is to use an interface program.

There are far  to many interfaces available  for the numerous types  of Bulletin
Boards to  cover in this  document. It  would at least  double the size  of this
document to cover them all. So instead we will cover how to obtain one, and what
the best interfaces provide.

To obtain  an interface  designed specific  to your  BBS software  call our  BBS
"Valley of the  Sun". The number is listed  on the cover page  of this document.
The interfaces can be  found in file area  B (BiModem support). You  can quickly
find the ones available for your software by performing a text search on the BBS
software name. They will normally contain their  own documentation on how to set
up  the interface  for  your particular  board. Most  of them  are very  easy to
install. In  the case  of our Opus  interface, and  PCBoard interface,  they can
usually be installed in less than 15 minutes.

A good interface will accomplish the following:

     1. Establish the environment for this user. This entails building a
        directories that this particular user has access to, and setting
        time and size limits for bimodem.
     2. Execute BiModem.
     3. Update the bulletin board files reflecting the transfers that just
        occurred.

The last step usually varies quite a bit, depending on the  boards requirements.
Generally it involves updating user statistics, updating directory lists  (which
might include  asking for descriptions if they  were not supplied), and updating
log  files. In  some interfaces,  such  as our  PCBoard interface,  this  can be
programmed by you to  include ZIP testing, virus checking, or  whatever else you
would like to perform against uploaded files.

If for some reason you would like  to write your own interface, then download  a
file called TOOLKIT.ZIP.  This file contains file layouts used by BiModem, and a
discussion on how to write an interface.

                                   Appendix D

Appendix D - Performance

We wanted  a fair way to compare  BiModem and other protocols... So  what we did
was download  6 files using each of 3 transfer  protocols. We chose Telink which
was  about as  close  to  XMODEM as  we  could get  and  still support  wildcard
downloads, Zmodem which  is very popular these  days, and BiModem. We  timed the
execution  from the time we pressed enter to start the transfer until the system
responded ready to  enter more commands. The  tests were conducted using  a 1200
baud  modem connection from an 8mhz XT compatible  to a 10mhz AT compatible that
was running the BBS software (OPUS v1.03b). The XT was using Telix version 3.10.
Here are our results:

     Downloading 6 2136 byte files:

     Telink - 2 minutes 45 seconds
     Zmodem - 2 minutes 29 seconds
     BiModem- 2 minutes 07 seconds

     Downloading 6 2136 byte files and uploading 6 2136 byte files

     Telink - 5 minutes 30 seconds
     Zmodem - 4 minutes 58 seconds
     BiModem- 2 minutes 07 seconds

Of course, we knew BiModem would be much faster when uploading  and downloading,
but we didn't expect it to be so much faster when transmitting in one direction.
While  these  are  not very  scientific  test  results, they  show  the  kind of
performance boost you  can get with Bimodem.  Results may vary depending  on the
particular software  and hardware  used, so  we encourage  you to  run your  own
timing tests.  We have  attempted to be  as accurate  as possible  on the  rates
BiModem reports, but the transmission speeds reported by most transfer protocols
can be pretty misleading, some do not  account for buffering (Either hardware or
software). So use your stop watch and time the actual difference yourself.

Appendix E - Desqview Notes

BiModem  can be classified as Desqview  aware. It automatically determines if it
is running  in a Desqview environment. It will inform  Desqview when it is idle,
so that  other tasks  can have  more time  on the  system. BiModem  and all  the
support programs  have their  screen output  redirected to  the Desqview  screen
buffer  and  Desqview periodically  updates the  screen  from that  buffer. This
allows other  windows to  overlay the  BiModem window  with no  bleeding of  the
information. We  recommend that a separate window  be created for either BiModem
or BiMenu so that you can inform Desqview that this window is NOT swappable. The
amount of memory required  for BiModem is dynamic.  It depends on the  number of
transfer requests, upload  directories, and rejection directories.  We recommend
that you use 100k. This should cover 99.9% of situations. In our example we  use
115k  because BiMenu  is  in memory  with BiModem.  Here  is an  example  of the
required program parameters.

Appendix F - Double Dos Notes

BiModem is  Double Dos aware.  It automatically detects  the presence  of Double
Dos. It  changes the priority to 70/30 (70 for  BiModem). Then it informs Double
Dos when it  is idle. This  method yields excellent  performance results. On  my
386-25 when I run Telix in one partition and Norton SI in the other I get around
a 9. Even though  Telix is idle it is constantly checking for keystrokes. When I
run BiModem in  one partition  and Norton SI  in the  other I get  around a  26.
BiModem  also switches to BIOS mode when it  detects Double Dos. This allows you
to normally write directly to the screen (BIOS N) and when you run Double Dos it
will change for you. Switching  to BIOS slows down the display,  but it prevents
bleeding through to the other task.

Appendix G - Lantastic Notes

BiModem works  well in a  Lantastic environment provided  you follow  one simple
rule. You must  NOT replace the timer interrupt  (See BiConfig General Options).
Lantastic does all its  network work during a timer interrupt.  By replacing the
timer interrupt you are not allowing Lantastic to do  its job. We also recommend
setting up  Lantastic to  preserve stack  space. While  it is  not required  for
BiModem operation, the support programs only have a 128 byte stack and Lantastic
tells us they can use up to 256 bytes more than that.

Appendix H - Modem Settings

For most  modems no adjustments  are needed to use  BiModem. We have  found some
modems that have switch settings that can affect the CTS signal  handling. These
settings should be  made so that CTS  indicates the modem's readiness  to accept
data. Xon/Xoff software flow control should not be used.

Appendix I - 16550's

A 16550 is a chip that replaces  the standard communications chip (UART) in your
PC.  The advantage to a 16550 is  that it has a built  in 6 character buffer. We
have  found  that many  NAKs  are caused  by  bios, and  other  software running
concurrently  with BiModem,  disabling interrupt  processing for too  long. This
causes characters to be  lost. A good example of this is on AT's where the fixed
disk interrupt has a  higher priority than communications. Characters  cannot be
sent or  received while your  machine is servicing  a fixed disk  interrupt. The
built in buffer of the 16550 cause those characters not to be lost. Instead they
are buffered until the disabling condition has passed.

The buffering of the 16550 is programmable. BiModem will recognize that you have
a 16550  and automatically enable  the buffer. When  BiModem terminates  it will
restore the buffering state to its pre-BiModem state.

Appendix J - Error Messages

BiModem can produce a few messages. We  will describe them here and describe how
they can be caused. This first section of errors appears in the last error field
of the BiModem transfer screen.

File Sum  Error -  This appears if  both bimodems disagree  on the sum  of bytes
transferred. It only  occurs on noisy  lines. BiModem will automatically  verify
the file when this  occurs. If a  discrepancy is found, that  piece of the  file
will be retransmitted.

File  Not Found - This  is self explanatory.  Often it is caused  by a BBS whose
list of sending  directories is not all  inclusive. This causes  you to see  the
file in a directory list, but not be allowed to download it.

File exists, verify  - This is an  informative message stating that  BiModem has
discovered that file you are sending or  receiving already existed, and the date
or time of  the two files were  different. Following this message,  BiModem will
switch to the verify  mode of sending the file and only send the parts that have
changed.

File exists, Skip It -  This occurs if you are trying to send  or receive a file
that has the same date,  time, and size. You must specify Y to  'Skip files with
same date/time/size' in BiConfig under 'General Options'.  If you specify N (the
default), then BiModem would issue the previous message and go into verify mode.
After this error is displayed, BiModem will go on to the next file.

Create/Open Error - This  occurs if BiModem  has a problem  when it attempts  to
create or open the received  file. There are many things that can  cause this to
happen.  The most common  one is that the  receiving directory is mis-specified,
and BiModem is attempting to create the file in a directory that does not exist.

Timeout -  This occurs if  BiModem has waited too  long for a  response from the
remote  computer. It can be caused by many things. I will try to list a few. The
remote user has turned  off their modem, and your configuration is not set up to
detect loss of  carrier. See BiConfig 'Terminal  Options' - 'DSR causes  loss of
carrier', 'CD causes  loss of carrier'. A PCPursuit  connection has been broken,
but you're  still connected  to  the local  PCPursuit  station. See  BiModem  /E
argument.

Out of Space - This  occurs if the disk drive receiving a file  runs out of disk
space.

User Abort - This is an informative message stating that the user  at either end
has requested that this file be aborted.

File Rejected - This occurs when you try to  send or receive a file that already
exists in a rejection directory. See BiConfig "Filenames and Paths" - "Rejection
Directory List"

Password Failure  - This occurs when you try to  receive a file that is password
protected and you didn't supplied the correct password.

                                   Appendix J


Verify error - x - This message indicates that BiModem has detected a difference
between two files during a verification transmission. The x  indicates what 1024
byte block of  the 10 blocks being  tested. The x also determines  what block of
data will be transferred to correct the discrepancy.

Switched  to  Replace -  This  message  indicates  that  a verify  transfer  has
encountered more than 6 errors in a row. After this message, BiModem switches to
a regular transfer, instead of the verify transfer.

Rem Req Disallowed - This occurs when a transfer request is made from the remote
side of a BiModem that has said N to "Remote Requests Allowed" in BiConfig under
"General Options".

Seq  Err  xxx  yyy  -  This  occurs  when  BiModem's  transmission  packets  are
acknowledged out of sequence. It is usually caused by extremely noisy lines. The
xxx represents the block  number BiModem was expecting  to be acknowledged,  and
the yyy represents the block number that was acknowledged.

Too  Many Errors -  This occurs  when either end  of a  BiModem transmission has
exceeded  its "Maximum number of  errors allowed" in  BiConfig under "Limits and
Editing". After the error, BiModem terminates.

Nak - This  occurs when a 32  bit CRC does not agree  on the receiving end  of a
transfer. There  are many  things that can  cause this.  BiModem will  split the
block  into  two  blocks, and  retransmit  them.  The most  common  of  which is
telephone line  noise. However, if  you are getting  naks ALL the time,  and not
just occasionally, you might want to look into other causes. The 2nd most common
cause is interfering programs. It is possible  for a TSR, device driver, or disk
caching  software to disable  interrupts too  long on  occasion. This  can cause
BiModem  to loose characters. To check to  see if this is happening, modify your
config.sys and  autoexec.bat files  to contain  only the  bar essentials  (path,
files, buffers) and try the transfer again. If suddenly you don't see any nak's,
then you can reimplement the  items you removed, one at  a time, until you  find
the culprit. Once  you've located the offending  software you can, report  it to
the author to  see if they already have a fix,  find a similar product that does
not have the same  problem, or try installing a 16550 chip in place of your 8250
communications  chip. Other  common  causes  of naks  are:  bad cable  from  the
computer to the modem (especially if the modem is an MNP type), crossed wires in
your  house  phone  wiring  (there  are  many  inexpensive  phone  line  testers
available. Try radio shack.)

The  following  can be  seen in  the last  error  field of  the file  having the
problem. These correspond  to the DOS fatal  error codes. For  more information,
please refer  to your DOS  manual. BiModem  is more aggressive  about recovering
from  these errors than most programs. It will attempt to recover 3 times before
reporting the error.

Fatal error - Protected media      - This is DOS fatal error 0.
Fatal error - Unknown unit         - This is DOS fatal error 1.

The following can be displayed prior to BiModem terminating if a major error has
occurred.

Loss  of carrier  detected -  When this  happens is  dependant on  how you  have
BiModem configured. If in  BiConfig 'Terminal Options' you have said  Y to 'Loss
of  carrier on CD', then it will  happen whenever the Carrier Detect (CD) signal
is lost. If in  BiConfig 'Terminal Options' you have said Y to ' Loss of carrier
on DSR', then it  will happen whenever the Data Set Ready  (DSR) signal is lost.
What it  means is that  the other end  of a BiModem  connection has hung  up the
phone.  Another common cause is that you have  the wrong comm port configured in
BiConfig, or you're not using the config file you think you are, and the one you
are using has the wrong comm port in it.

Unable to establish  connection (CTS  low) -  This means that  when BiModem  was
starting up,  the Clear To  Send (CTS) signal  was low on  the comm port.  It is
usually  caused by specifying  an incorrect comm  port, or base  port address in
BiConfig. However, it can also be caused  by your modem not supporting, or being
configured  for,  CTS  handshaking.  If  you're   modem  does  not  support  CTS
handshaking, you can disable this check in BiConfig under 'Terminal  Options' by
setting the 'CTS/RTS hardware flow control' to N.

Unable  to establish connection  - This means  that BiModem did  not receive the
space/backspace sequence that it looks for in the configured amount of time. See
BiConfig 'Limits &  Editing' under 'Number of  seconds to wait for  connect'. On
initial installations this  can be caused  by interfering software not  allowing
BiModem to send or receive at all. See the discussion on the previous page under
'Nak' for the discussion on eliminating interfering software.

Remote  BiModem has  been altered  - This  means that the  BiModem that  you are
talking to has been altered. The  connection is terminated to avoid the  ability
of the altered BiModem to send viruses to your computer.
