- TFLINK.DOC
- ----------
-
- This file contains minimal startup instructions for TFLINK.EXE. It
- will be written properly when I get the time, and if necessary.
-
- TFLINK.EXE is a TSR program that connects a currently running TFPCX
- TSR to the second serial port on a DOS system. A Linux (or other) PC
- can then plug into this second port, and use the DOS PC and Baycom
- modem combination together as a "virtual" hostmode TNC.
-
- This is the normal way that TFPCX is used with DOS
-
- +-------------------+
- | DOS: | COM1
- | SP/GP... -> TFPCX | <------> Baycom <--> Rig
- +-------------------+ modem
-
-
- And here is the way it can be used with Linux, via TFLINK
-
- +-------------+ +-----------------+
- | Linux: | ttyS1 COM2 | DOS: | COM1
- | TNT | <----------> | TFLINK -> TFPCX | <------> Baycom <--> Rig
- +-------------+ +-----------------+ modem
-
-
- To set this up, first load TFPCX on DOS, with the command
-
- TFPCX -PCOM1 ...other options...
-
- This starts TFPCX running with the Baycom modem connected to port
- COM1.
-
- Next, load TFLINK on DOS with
-
- TFLINK -PCOM2
-
- This will start the transfer of data between COM2 and TFPCX running on
- the default interrupt of INT FD. Serial line speed is 9600 baud by
- default (can be set by options to TFLINK), 8 bits, no parity, 1 stop bit.
-
- Use 'TFLINK -H' for a full listing of TFLINK options.
-
- It should now be possible to connect to TFPCX as a "virtual" TNC from
- Linux. A simple test terminal shell script, tfterm, is provided -
- this shell script can be run on Linux to test the connections. Once
- this combination is working, it should then be possible to run Tnt on
- Linux.
-
- When the session is finished, TFLINK can be unloaded. To unload the
- TSRs, it's important to remove them in reverse order. To remove
- TFLINK, use
-
- TFLINK -U -PCOM2
-
- The -P option is mandatory with all usages of TFLINK except -H.
-
- Then TFPCX can be unloaded with
-
- TFPCX -U
-
-
- Notes:
-
- - Speeds over 9600 baud can cause problems on my system, for reasons
- as yet unknown. 9600 baud is fine for Tnt use in any case.
-
- - TFPCX 2.1 is the version I use. I tried with an earlier one, and
- Tnt was not able to sync with it; maybe some disagreement between
- TFPCX 1.10 and Tnt?
-
- - You can load such things as the TFPCX 'MYCALL' either from a
- TFPCX.INI file on the DOS PC when starting TFPCX, or from the TNC
- initialisation built in to Tnt (or whatever Linux terminal you are
- using).
-
-
- Have fun. Best regards,
