Some more thoughts.....
A serial interface would be simpler, but I was hoping not to use one, since
serial ports are at a premium on most machines. Rig control, TNC and the 2
basic ones are already gone. Also, keeping the keyer board internal to the
PC would reduce the costs as there would be no case or power supply.
