I've got a Vector MZ with a ZCB processor and
BitStreamer II I/O board; at present the 4.0 'C' series
monitor program uses serial port A on the BitStreamer
for its console, but I want to remove the BitStreamer
and use the serial port on the ZCB instead.

At a fast glance I can't see a jumper setting that
would accomplish that; anybody out there have any
experience/ideas by any chance?
