Hello OM's,
Before I try to implement the PTT in cwdaemon, can you explain how the PTT
should work exactly?
As far as I know PTT should become activ a few milliseconds before the first
char is send and must stay a while longer activ after the last char.
The pin must be pin 7, RTS. Thats what I read from other keying and/or digital
programs.
What is the main reason for this PTT feature? Delayed switching of a PA? Or
using as PTT key for SSB? And what times for delay is handy?
Sorry for so many questions only to switch one pin , hi. :-)

Hello Wolf,
As far as I know, some rig's need a different line to turn transmit
on/off, because the 'VOX' won't work in CW mode.
I have received a patch from Lada, OK1ZIA which contains basic PTT
support (but without a delay). Lada has also used vsnprintf in the code,
which prevents buffer overflows in cwdaemon. There is also support for
changing the keyer port on the fly from tlf (could come in handy if you
have different transmitters :-)).
His code takes some time to understand, but generally it is very well
written. I have attached his patch.
There is some support for what lada calls 'SSB source switching', a pin
on the printer port is designated to switching the MIC input either to
the microphone or the soundcard (see the README after applying the
patch). He uses this in a VHF contest program.
Let me know what you think of the code. I currently don't have the time
to review it thoroughly, but there may be some interest stuff in there.
