I've tried unsuccessfully to setup an IBM Thinkpad 700/PS2
with Xircom multiplexor. I'm using Xircom Token Ring pocket adapter, if
connected directly to the parallel port there's no problem, but if a use
the multiplexor it simply hung. I've called IBM and Xircom to no avail.

I've just set up some twisted pair xircom adapters and had some
problems with setting them up. After talking to xircom I was told that
the adapter HAS to be plugged into the B port on the mux and the printer
HAS to have power for the mux to work (turned on and plugged into the mux).
In my case I had to load the odi or packet driver twice if the adapter
was plugged into the A port on the mux. Once I moved the adapter
to the B port everything worked fine. So much for the manual.
Incidentally I've found the Xircom PPX parallel port multiplexor
to be an excellent add-on to allow printing while connected to the network.
You print to LPT1 while using LPT2 for the network. It can
be be slow - but if you print to LPT1.DOS it is much better.
