[RTTY] Occasional ptt dropout in mmtty/writelog

[Charles Morrison]

Im a day late and a dollar short Dave, but I had the same problem with one
of the 1000D's.  I was doing computer ptt, and it would occasionaly hang.
RF Into the Yaesu IF-232 box was doing it.  I left rig control on the box,
but changed PTT to a direct key on the serial port and changed it in
Writelog.  No problem since then.  Funny thing was that the all in the port,
single wire, someone home brewed cable, didn't have a single problem.

N6DE mentioned this problem in his naqp writeup, and it reminded me that the
same thing happened here three times during the 10 hour contest:
------------------------
There was one intermittent problem on our second station where the PTT would
occasionally drop in the middle of a message, but our MMTTY window in
Writelog kept printing the transmit message as if it still still sending it.
I remember seeing this problem at NN6NN for WPX RTTY, but still don't know
what is causing it.
-------------------------

My setup is win98se on a Pentium 200, TS-850's with PTT digitally commanded
over the rig control RS-232 lines. WL 10.46G, MMTTY 1.64B. Any ideas for a
solution? I searched the archives, but couldn't find reference to this
issue.
