I recently picked up a DFMSA Port Selection Device which I would
like to use with my non-DEC PC clone.  Not having a user's manual or
access to one,  is there a simple explanation of how to use
the DFMSA?  I am guessing that a few control codes are used to
switch the RS232 lines.  I would very much appreciate it if some
kind soul could explain how to use this very useful device.

Thanks in advance,
