Using the Serial Interface
If you have a serial printer, modem, mouse, or any other
peripheral with a serial interface, you can connect it to one of
two serial (RS-232C) ports on the back of the computer. Your
computer uses IBM-compatible, 9-pin, male connector, so be
sure you have the proper cable. If you are not sure which one
you need, or whether you have the right one, check with the
store where you bought the cable.
