║ GT-HELP ║ PROTOCOL.BBS - the Upload and Download Protocols you offer
╚═════════╩════════════════════════════════════════════════════════════
The PROTOCOL.BBS file is used when a caller executes the download or
upload commands.
It has two parts:
a) The first line, which "looks" like a comment and is not seen by the
caller, tells GT which protocols you intend to support.
b) The remainder of the file is shown to the caller.
┌───────────────────┐
│ The Protocol List │
└───────────────────┘
The first line must be a list of the CHARACTERS that you wish GT to
recognise as valid protocol selection characters. It should begin
with a semicolon in column 1 -- for example :
;xwt1ybmkszgi;
Those which correspond to *internal* protocols have fixed meanings :
x Xmodem
y Ymodem
b Ymodem Batch
1 1K Telink
w WXmodem
m Megalink
s Sealink
*Other* characters can be chosen for external protocols. The usual
ones are:
z Zmodem
k Kermit
g Ymodem-G
i bImodem
Of course, you should only include these characters in your protocol
list if you obtained the associated external protocols and have set up
their associated batch files.
There is generally no advantage in disabling any of the internal
protocols, though you can do so by deleting the character from the top
line if you wish.
┌──────────────────────┐
│ The Protocol Display │
└──────────────────────┘
The remainder of the the file is shown to callers and can be edited any
way that makes sense. An example is :
┌────────────────────────────────────────────────────────┐
│ <X> Xmodem -- most comms programs support this │
│ <Z> Zmodem -- better if you have it │
│ <I> bImodem -- send and receive at the same time │
│ │
│ [t] Telink [y] Ymodem [k] Kermit │
│ [w] WXmodem [1] 1k Telink [b] Ymodem Batch │
│ [s] SEAlink [m] MegaLink │
└────────────────────────────────────────────────────────┘
┌───────────────────────────────┐
│ Installing External Protocols │
└───────────────────────────────┘
As their name implies, the external protocols require external programs
and are therefore optional.
To configure *additional* external protocols :
a) Choose a protocol selection character (an alpha character not
already in the list above) and add it to the protocol.bbs
list
b) In GT ALT-I, find the external protocols table and specify a 2
character reference which you will use as the first two
characters of your batch files (xxRX.BAT for sending,
xxTX.BAT for receiving).
c) Also in GT ALT-I, specify the overlay characteristics for the protocol.
Hint: Overlaid is safe, but slow - non-overlaid may work if you
have enough free memory.
d) Use the Additional Protocols option in GT-Help to create and
edit the batch files.
e) Install any other files which the protocol itself requires.
