You can connect the RS-232 port directly to the serial port of the Mac.
Of course you'll need a special cable (as if there were such a thing as
a standard RS-232 cable).  Use the pinouts found in macTEP, but swap
pins 2 & 3 on the DB-25 side.  You might also have to connect pin 2  (+5v)
on the DB-9 to pin 6 (Data Set Ready) on the DB-25.  As in all cases when
connecting two devices for the first time, be prepared to experiment.
