It should work just fine. I have had this idea before, but I never got around
to finding a source of information on serial multiplexers. A replacment
serial.device should do the trick, and you would want the mulitplexer to not
have any inband controls so 8 bit protocols would still work.
Does anyone know where I can find out about multiplexers prices and protocols?
This might make a good summer project, if a multiplexer would be cheaper then
a multi-serial card.
