The serial ports (also referred to as RS-232 asynchronous communications
ports, or COM ports) 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. Use only shielded cables with the serial ports.
