Connecting a Serial Device
Your computer has two serial ports for connecting serial devices such as
serial mouse or serial communication device (modem).
Follow this procedure to connect a serial device:
1. Make sure the “Serial Port COM1/COM2” item is set properly in the
BIOS Setup program. (See “Advanced Menu” in Chapter 5 for
information.)
2. Make sure the computer is not turned on.
3. Slide the release latch towards the right to open the port cover.
4. Plug the device cable to the serial port on the rear of the computer.
5. 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.
