A serial null modem cable usually requires pins 2, 3 and 7. Pin 7 is the signal ground. Pin 2 on one end should connect to pin 3 on the other, and vice versa. Those are the transmit and receive signal pins. Sometimes pins 4 and 5 must also be used, but that's less common. -- Geoff Rowell [EMAIL PROTECTED] _______________________________________________ Boston-pm mailing list [email protected] http://mail.pm.org/mailman/listinfo/boston-pm
