4-4 Expanding Your Computer
Connecting a Serial Device
Your computer has a serial port for connecting a serial device such as an
external modem.
Follow this procedure to connect a serial device:
1. Make sure the “COM1 Ports” item is set properly in the SCU
program. (See “Components Menu” in Chapter 5 for information.)
2. Make sure the computer is not turned on.
3. Plug the device cable to the serial port on the rear of the computer.
4. 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.
