I built the interface on the old N1RCT page and use it for CW and FSK from
the same COM port (RITTY or MMTTY). Works with CT too. Note that the
radio frequency control is on a DIFFERENT COM port, I don't think you can
make an interface that works for all three, or is that what you were
speculating?
