4-4 Expanding Your Computer
Connecting a Serial Device
Your computer has one serial port for connecting a serial device such as a serial
mouse or serial communication device (modem).
Follow this procedure to connect a serial device:
1. Turn off the computer.
2. Plug the device cable to the serial port on the rear of the computer.
3. Turn on the computer.
NOTE: Portable modems that derive power through the serial port cannot be used
with the computer. Instead, use a modem that is powered by its own internal
battery or external AC power.
