I need to multiplex several RS232 lines on a tethered mobile robot
and send the data on a single twisted pair (preferred) or coax. I am
considering using the AMD TAXI chips to mux/demux 8 serial lines (rates 
between 300 and 19.2Kbaud. Before I build this I thought I'd find out
if anyone builds one of these commercially or if an existing design  
is in the public domain. 

Please email responses... I'll summarize to the net.
