Hi Ivo. > Hi Riley, thank you and others for so fast feedback. It shoud > keep me going. >> Personally, I'd like to see the following options from such >> a driver: >> 1. With or without sidetone.

Is this compatible with doing the above ??? >> 2. Output either straight keying or tone encoded.

The PTT is thus keyed for the entire message. > I can make an option for PTT but from where should come the > sound? From PC speaker - requires hardware intervention (read: > soldering wires inside PC) or from sound blaster - requires some > more learning :-)) To give an example of my preferred option using the parallel port, I would designate D0 as PTT and D1 as Audio In. Presumably something similar could be done with the serial port ??? >> 3. Choice of port to use.

It is done by "make cwup1" for COM1 and "make > cwup2" for COM2. So if I need to change the port, I have to recompile? I would much prefer a command-line option. In fact, the attachen manpage describes the interface I would like to see... > Of course that you can use supplied commands inside Makefile > somewhere else. I will add support for LPT keying also.
