*** REPLACE THIS LINE WITH YOUR MESSAGE ***

The following four connections will make your Mac RS-422 connector into a
standard RS-232 connector.  Building a cable with a female 9-pin D connector on
one end and a female (or male, depends upon your modem) 25-pin D connector on
the other is the easiest way to do this.

	RS-422			RS-232
	(Mac 9-pin)		(Modem 25-pin)

	3			7
	5			2
	7			20
	9			3

Good telecommuning!
