[Dx4win] rtty

[Larry Gauthier (K8UT)]

Don,

The following is part of an email exchange I had with WK6F about 18 months 
ago. He was able to get his KAM plus working with DX4WIN (using the null 
serial cable route) by using these control sequences.

Hope this helps you also,

Ken,

I use MMTTY in TNC241 emulation mode... primarily because that's what I
could get to work with my DX4WIN logging program. (I run MMTTY and DX4WIN
within one computer, with null modem software, so that they talk to each
other with a "virtual" null modem cable).  Disclaimer: I know nothing about
KAM's cmd control codes -- but this is what happened when I hacked around
with it --

As an experiment, I switched to KAM emulation. MMTTY sent the following
screen and prompt to DX4WIN...
=====
MMTTY Ver1.64 (C) JE3HHT 2000-2003.
TNC emulation.
Command 'RTTY'
To RX:Ctrl+C,R
To TX:Ctrl+C,T

cmd:
=====
>From that "cmd:" prompt, if I type "RTTY<enter>" I get a "-RTTY 45-"
response from MMTTY. Then, if I type "<ctrl+C>R", receive character begin
arriving in the emulation receive window. If I type "<ctrl+C>T the software
kicks MMTTY into transmit mode and send whatever characters are in the
outbound buffer. I can then toggle back-and-forth between rcv and xmt by
using those control codes. If I type <ctrl+C>X, MMTTY halts emulation and
returns to the "cmd:" prompt.

Not sure if this helps you or not -- but if you have some specific tests
you would like me to try send me an email off-line and we can hack at it.
