- BETA 000
- --------
-
- The UCDAVIS dialer script was too long to implement fully plus I
- couldn't make head nor tail of it. The main bits are implemented but
- the wierd stuff at the top will have to be added manually with a text
- editor after config.prg has run successfully.
-
- Script Candidates
- =================
-
- A script must have all critical variables configured for the provider.
- Neither can a script be user or modem specific. User and Modem
- specific information must be generalised.
-
- Maintenance
- ===========
-
- The names and hierarchical positions of items within the SETUP
- directory are best considered fixed. The programs within SETUP all
- rely heavily on shel_read() to obtain their execution path - the term
- current working directory (cwd) applies to this path *not* the path
- which can be obtained from TOS which can easily be different when
- multitasking. A point about shel_read() ...
-
- shel_read() should return the full path including program name and
- drive specification. Under Older Gem's it does not, it returns only
- the program name which is useless. In order to maintain backwards
- compatibility, the string returned from shel_read() is searched for a
- ':' and if one is not found, Dgetdrv() and Dgetpath() are used and the
- program name appended which emulates the newer shel_read() for all but
- the silliest circumstances.
-
- The batchfiles used all rely on the cwd. The cwd is obtained and the
- path specified in the batchfile is appended to it to build a fully
- specified name in all cases.
-
- The rest of this text assumes that the contents of SETUP are unchanged
- and that wherever the SETUP directory is written, that the user read
- this as the full path to SETUP.
-
- Adding a new Provider
- ---------------------
-
- setup\install\provider.dat is a simple batchfile, one line per
- provider. Each line consists of two fields - the first field is the
- path to append to cwd and is delimited by a single space character.
- The second field is all the remaining text until eol and is the actual
- text to display in the list of providers which the user sees in the
- install program. E.G.
-
- scripts\newprov\install.dat New Provider
-
- means that setup\install\scripts\newprov\install.dat is the batchfile
- to use when installing for "New Provider" which will be visible to the
- user to select. The full path built must not exceed 128 characters and
- the length of the text to display in the provider list must not exceed
- 40 characters currently.
-
- Providers appear in the display window in the order that they appear
- in provider.dat so it is recommended that the entries are manually
- sorted into alphabetical order (case insensitive) when any non
- alphabetical character preceeds an alphabetical one (ie 3<a etc).
- '
- The directory setup\install\scripts\newprov should be created. Copy
- default.cfg and dial.scr into it and ensure that the dialer script
- name in default.cfg is actually dial.scr.
-
- Now either create setup\install\scripts\newprov\install.dat with a
- text editor or copy one of the others and modify it.
-
- install.dat consists of one line for each file to be copied, typically
- two lines currently, one for default.cfg and one for dial.scr. Each
- line consists of a source field and a destination field, separated by
- a single space. The source field is a path relative to cwd, the
- destination field consists simply of the destination filename (the
- name can be changed during the copy but there is no reason to
- complicate matters by actually doing so)
-
- The provider is now part of the system. A point to note is that
- install.prg copies the files unchanged to their destinations but
- config.prg will strip out comments so the comments in the originals
- might as well be removed.
-
- A new provider script *must* have the following predefined:
-
- ALLOCMEM = 150000 reasonable general purpose value.
- SERIALPORT = Modem 1 stands most chance of working.
- CDVALID = TRUE most modems support it.
- DIALFILE = dial.scr *must* be this.
- CLIENT_IP = 0.0.0.0 *always* zero.
- TTL = 64 leave all these unchanged ...
- PING_TTL = 255
- MTU = 1006
- MSS = 966
- PKT_SIZE = 2048
- DFB_SIZE = 1024
- RCV_WND = 4096
- UP_RESPONSE = 2 *must* be 2 without a good reason.
- USERNAME = {nouser} recommended text.
- HOSTNAME = {nohost} recommended text unless the provider
- assigns dynamic IP in which case this
- will be fixed and should be left
- unchanged. If there is a fixed part to
- the domain then it should be appended.
- An example is {nohost}.demon.co.uk.
- FULLNAME = {noname} recommended text.
- NAMESERVER = xxx.xxx.xxx.xxx *must* be valid.
- IRCNICK = {nonick} recommended text.
- IRCSERVER = {noserver} recommended text.
- IRCPORT = 6667 recommended text.
- IRCPONGMSG = WWW installer! recommended text.
- EMAIL = {noemail} recommended text.
- SMTP_HOST = {nopost} recommended text.
-
- BAUD_RATE = 19200 *never* exceed this.
- HANGUP = ATH recommended text.
- PREFIX = ATDT recommended text.
- INIT = ATZ recommended text.
- CONNECT_WAIT = 35 minimum value.
- REDIAL_DELAY = 20 minimum value.
- PHONE_NUMBER = 9549666 *always* remove PHONE_NUMBER variables!
- SUCCESS = CDWAIT *must* be present.
- FAILURE = BUSY *must* be present.
- FAILURE = NO CARRIER *must* be present.
- FAILURE = NO DIALTONE *must* be present.
- FIND = ogin: leave unchanged.
- RESP = {nohost} recommended text
- FIND = word: leave unchanged.
- RESP = {password} recommended text.
- FIND = ocol: leave unchanged.
- RESP = slip leave unchanged.
- FIND = IP if present, leave unchanged .
- RESP = $GET_IP if present, leave unchanged.
-
- HTTP_PROXY and HTTP_PROXY_PORT *must* be left unchanged if supplied in
- a script. If they do not exist, or they exist and are not valid, then
- they *must* be removed from the script.
-
- Archaic variables should be stripped to save confusing the end user.
- Comments and blank lines are also stripped along the way so remove
- these also.
-
- Note
- ----
-
- EMAIL and SMTP_HOST are supported currently so that Cab "mailto" can
- be supported. They should not be considered permanent just yet, as a
- future Cab may allow them to specified there.
