Personally, I'd like to see the following options from such a driver:
1. With or without sidetone. In other words, the user can
choose whether they can hear the morse through the PC's
speaker or not.
2. Output either straight keying or tone encoded. Whilst HF
tends to use direct keying of the transmitter, VHF and
above tends to use a tone that is modulated by the keying
signal, being 0 Hz for off and anywhere between 600-1500
Hz when on. The PTT is thus keyed for the entire message.
3. Choice of port to use. From the description, you've used
a specific serial port for the morse output, but that is
probably less than optimal.
Comments?
Best wishes from Riley.
