Macintosh: Generic Pinouts for 9600 Baud V.32/V.42 Modems


What are the generic pinouts for connecting a Macintosh to a high-speed
9600 baud V.32/V.42 modem?

Here are the generic pinouts:

 Modem              Macintosh
 1-7                 4-8
 2                   3
 3                   5
 5                   2
 4                   1

These pinouts apply to all "V" series modems and all Macintosh computers.
Older Macintosh computers have slightly different serial ports than the
later machines and may not support the fastest possible Macintosh-to-modem
speeds.
