[comp.sys.mac.misc] RS232 connection problem solved

Thanks to all that responded about how to hook up an rs232 port to
the db9/rs422 that the mac uses.  As it turns out, the two standards
are more or less compatible; all you need to do is have a proper cable
that hooks up the right pins.

I was able to buy a cable (I believe most apple dealers carry them)
for hooking up the db9 connector to the 25-pin rs232 port on the back
of my Hayes modem, for a very painless 15 dollars or so.
