When I worked for Pinnacle Systems, we had a number of customers complaining of
the same problem - we had it real bad at our office because the serial cables
run in the ceiling over noisy stuff like light fixtures.  The best fix I
ever found was to tie the RxD line to ground with a 10K resistor.  If you
do this on the computer end of the cable, you don't have to disconnect the
unused (or switched off, like with a T-switch) cables.
