[TRLog] Keyer Challenge

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.
