Serial Ports
The serial ports (also referred to as RS-232 asynchronous communications ports, or COM
ports) can connect modems, printers, peripherals and other computers to the system. The serial ports
(labeled 1 and 2) are 9-pin, male DB9 connectors. If connecting a serial device with a 25-pin DB25
connector, use a 25-pin to 9-pin adapter cable to mate with the serial port on the system. Only shielded
cables should be used with the serial ports. Refer to page 58 for information about the serial port
functionality of the FDC37C932.
