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. -- Brian Waters !{iuvax|pur-ee}!bsu-cs!jbwaters
