this work as a null modem cable ?


I have a cable that came with my modem circa 1999. It has two parallel port connectors and one serial port connector. I find myself in need of a null modem cable, will this thing do the job ?

Probably. It depends on how it is configured.

Serial cables can have both 25 pin and 9 pin connectors on the ends. Now days 9 pin is standard on PC's but I think external modems usually still have 25 a pin connector.

How is the cable configured? You might have to check with an ohm meter. Its the same for a 9 pin or 25 pin.

Pin 2 - Pin 3
Pin 3 - Pin 2
