I believe that it was this group that included the PC reading a switch
thread......

Anyway, I just came across an article in 12 July issue of Electronic
Design that has a circuit using the serial port (yea, I also thought of
that :-) ) and even included a schematic and little (ugh) basic program
to read the port.  

Thought I'd pass this along in case anyone still cares
