- OS/2 File Transfer Protocol driver 1.5 (c) 1992 by Mikael Wahlgren
- ===========================================================================
-
- This is an external file transfer protocol driver, designed to supply
- other programs with file transfer capabilities. It is specially
- designed with Os2You (OS/2 Remote Access Facility by Mikael Wahlgren)
- and the Maximus/2 BBS program in mind.
-
- This protocol driver supports the following file transfer protocols:
-
- Xmodem/ChSum
- Xmodem/CRC
- Xmodem-1K
- Ymodem (batch)
- Ymodem-G (batch)
- Zmodem
- Kermit (*)
-
- (*) The Kermit file transfer protocol is supported in combination with
- the CKermit file transfer program (tested with CK5A188 release).
- CKOKER16.EXE must be available in the PATH.
-
- To install this program you copy all *.EXE and *.MSG in a directory
- specified by your PATH and DPATH statements. You copy the ZIP.DLL
- file into a directory specified by your LIBPATH statement.
-
-
-
- Possible return codes (ERRORLEVELs)
- ===================================
- ERR_NO_ERROR = 0
- ERR_OPEN_FILE = 1
- ERR_INIT_SESS = 2
- ERR_DISK_READ = 3
- ERR_DISK_WRITE = 4
- ERR_COM_READ = 5
- ERR_COM_WRITE = 6
- ERR_CANCEL = 7
- ERR_FATAL_COM = 8
- ERR_NO_DCD = 9
- ERR_LOCAL_CANCEL = 10
- ERR_TIMEOUT = 255;
-
- (these error codes are only valid for Xmodem and Ymodem family protocols.
- For return codes of Zmodem and Kermit, see the M2Zmodem and CKermit
- documentations)
-
-
- Special instructions to run the program with Os2You
- ===================================================
- This program is especially designed with Os2You in mind. The recommended
- protocol is Ymodem, which is default. To use this protocol driver with
- Os2You, just copy the files into a pathed directory and run the following
- commands:
-
- Os2FTP -sC:\Files\*.DAT (to transfer files C:\Files\*.DAT)
- Os2FTP -rC:\Download (to receive files into C:\Download directory)
-
- If you want to use another protocol, like YmodemG, the commands will look
- like:
-
- Os2FTP -YMODEMG -sC:\Files\*.DAT
- Os2FTP -YMODEMG -rC:\Download
-
-
-
- Instructions on use with BBS
- ============================
- Copy all of the distributed files into your Maximus home directory.
- To interface these protocols with the BBS (Maximus/2) you will have
- to add the following lines to your PROTOCOL.CTL file:
-
- ------------------------------- cut here -----------------------
- Protocol Ymodem
- Type Batch
-
- LogFile Ymodem%K.Log
- ControlFile Ymodem%K.Ctl
- DownloadCmd OS2FTP.Exe -nosts -s#Ymodem%K.Ctl
- UploadCmd OS2FTP.Exe -nosts -r#Ymodem%K.Ctl
- DownloadString Send %s
- UploadString Get %s
- DownloadKeyword Sent
- UploadKeyword Got
- FilenameWord 1
- DescriptWord 0
- End Protocol
-
-
- Protocol G-Ymodem
- Type Batch
-
- LogFile YmodG%K.Log
- ControlFile YmodG%K.Ctl
- DownloadCmd OS2FTP.Exe -ymodemg -nosts -s#YmodG%K.Ctl
- UploadCmd OS2FTP.Exe -ymodemg -nosts -r#YmodG%K.Ctl
- DownloadString Send %s
- UploadString Get %s

-
-

- DownloadString Send %s
- UploadString Get %s
- DownloadKeyword Z-Sent:
- UploadKeyword Z-Received:
- FilenameWord 1
- DescriptWord 0
- End Protocol
-
-
- Protocol Kermit
- Type Batch
-
- LogFile KERM%K.Log
- ControlFile KERM%K.Ctl
- DownloadCmd OS2FTP.Exe -kermit -tmp\KERM%K -s#KERM%K.Ctl
- UploadCmd OS2FTP.Exe -kermit -tmp\KERM%K -r#KERM%K.Ctl
- DownloadString Send %s
- UploadString Get %s
- DownloadKeyword Sent
- UploadKeyword Got
- FilenameWord 1
- DescriptWord 0
- End Protocol
-

- ------------------------------- cut here -----------------------
-
- You should also ensure that the PROTOCOL.CTL file is included in
- your MAX.CTL file (i.e. ensure that the MAX.CTL file is ended with
- a line like "include PROTOCOL.CTL")
-
- The Xmodem protocols should be possible to use in this way as well, but
- I can't see the use of this.
-
- There is no guarantee that these file transfer protocols work in all
- situations. Especially the Zmodem protocol is untested for this kind
- of usage. I am not legally responsible for any harm that your system
- may suffer from, by the use of this program.
-
- NOTE that if you use the Kermit protocol, the CKOKER16.EXE file MUST be
- available in the PATH (it is _NOT_ sufficient that it is in the current
- directory!). This version of OS2FTP is built to work together with
- CKermit version 5A188 released 25 January 1993. The CKermit package
- includes two different Kermit implementations CKOKER16.EXE for 16 or 32-
- bit OS/2 and CKOKER32.EXE for 32-bit OS/2. HOWEVER there seems to be
- a serious bug in CKOKER32.EXE (the 32-bit version) which prevents it
- from working for this kind of use. OS2FTP is built to first look for
- CKOKER32.EXE and if that can't be loaded try with CKOKER16.EXE. Thus
- I recommend you to REMOVE CKOKER32.EXE and ensure that ONLY CKOKER16.EXE
- is available. This as long as the bug in the 32-bit implementation
- remains unfixed. Also note that becuase the Kermit protocol is
- implemented using an external program, there are some limitations with
- regard to this. These limitations are (when using Kermit protocols):
-
- * All files are transfered to/from a temporary directory created by
- OS2FTP. This directory will normally be maintained automaticly
- by OS2FTP. This means that if a user request a file transfer batch
- of 3.5 Mbytes to/from the system, this will require 3.5 Mb of temporary
- disk space.
-
- * If a user cancels a Kermit download, the BBS will still treat this as
- a completed download (when adding to the download counters and so on).
-
- * The Kermit protocol can not be aborted by pressing Ctrl-X several
- times, as stated by Maximus before a file transfer begins.

-
- Programming information
- =======================
- If you want to use OS2FTP with your own application you can easily interface
- to OS2FTP. To send files with XModem, Ymodem, Ymodem-G, Zmodem or Kermit
- from your application, you create a text file (let's call it OUT.TXT) like
- this:
-
- Send C:\MyPath\MyFile.TXT
- Send C:\MyPath\Package.ZIP
- Send C:\Another\Demo.TXT
-
- To start the file transfer you invoke OS2FTP with the following command:
-
- For Xmodem: OS2FTP -xmodem -nosts -s#OUT.TXT
- For Ymodem: OS2FTP -nosts -s#OUT.TXT
- For Ymodem: OS2FTP -ymodemg -nosts -s#OUT.TXT
- For Zmodem: OS2FTP -zmodem -s#OUT.TXT
- For Kermit: OS2FTP -kermit -tmp\TMPDIR -s#OUT.TXT
-
- To receive files with Xmodem, Ymodem, Ymodem-G, Zmodem or Kermit to your
- application (into the directory C:\InPath you create a text file (let's
- call it IN.TXT) like this:
-
- Get C:\InPath
-
- To start the receive you invoke OS2FTP with the following command:
-
- For Xmodem: OS2FTP -xmodem -nosts -r#IN.TXT
- For Ymodem: OS2FTP -nosts -r#IN.TXT
- For Xmodem: OS2FTP -ymodemg -nosts -r#IN.TXT
- For Zmodem: OS2FTP -zmodem -r#IN.TXT
- For Xmodem: OS2FTP -kermit -tmp\TMPDIR -r#IN.TXT
-
- After a successful transfer a log file will be created called OUT.LOG
- (if the filename OUT.TXT was used) or IN.LOG (if the filename IN.TXT
- was used). If the file transfer operation was done with Xmodem, Ymodem
- or Kermit each row in the log file should be scanned for the following
- keywords (there is no guarantee that the keyword will be placed first on
- the row):
-
- Sent yyy\xxx (yyy\xxx is the complete path to file received)
- Got yyy\xxx ( d:o )
-
- If the file transfer was performed using Zmodem, the keywords are:
-
- Z-Sent: yyy\xxx (yyy\xxx is the complete path to file received)
- Z-Received: yyy\xxx ( d:o )
-
- The log file should be erased before using OS2FTP again.
-
-
-
- Release log
- ===========
- 1.3 Modified for BBS usage
-
- 1.4 Ymodem-G transfers can now be cancelled correctly with Ctrl-X.
- Ymodem-G didn't detect carrier loss, this is fixed.
-
- Kermit protocol added.
-
- 1.5 Kermit handling modified to work with CKermit 5A188 from
- 25 January 1993.
-
-
- Licensing information
- =====================
- If you haven't registered the Os2You/M2Zmodem/OS2FTP file transfer option,
- this program will introduce an intentional delay before transfering any
- files. Note that the Ymodem protocol used in this protocol driver is exactly
- the same driver that is built in Os2You, available via the Service functions
- menu.
-
- To register, use the included order form and specify the
- Os2You/M2Zmodem/OS2FTP item.
