MAKING A NULL MODEM CABLE FOR MAC TO PC LINKS
---------------------------------------------

The Apple Macintosh has a special, 8-pin DIN serial connector.  This port can 
be used to "hard wire" the Mac to a PC running TBBS.  If you cannot purchase 
an "off the shelf" cable for this purpose, you can make one using this 
diagram:
