What Dave Carter was saying when he explained the dual use of the serial port
for MIDI and lower baud rate I/O was that you can use your serial port for
both, just not at the same time.  The Amiga serial port already supports MIDI
rates, and there is a standard software interface to the serial port.  When you
buy a MIDI connector you get a MIDI IN, a MIDI OUT, some models provide a MIDI
THRU, and a serial port pass-through.  These are just connectors and a few
inexpensive parts to protect against line surges, etc.  You plug the MIDI
connectors into the serial port, then your printer into the serial pass-through
on the MIDI adapter.  The only time you can't use your serial port for printing
is while you are using it to send or receive MIDI data, as the serial data
destined for your printer would corrupt the MIDI data.  There is no need to
plug and unplug your printer however; you simply wait until your MIDI I/O is
done, then print over the same port.  Clear?
