COM (Serial) Ports
COM 2
COM 1
The serial ports are RS232 asynchronous communication ports with 16C550A-
compatible UARTs that can be used with modems, serial printers, remote display
terminals, and other serial devices.
Connecting External Serial Ports
Your COM port may come mounted on a card-edge bracket. Install the card-edge
bracket to an available slot at the rear of the system chassis then insert the se-
rial port cable to a COM connector. Make sure the colored stripe on the ribbon
cable is aligned with pin 1 of the COM connector.
BIOS Setting
Configure the serial ports in the Integrated Peripherals submenu (“Onboard Super
IO” section) of the BIOS. Refer to chapter 3 for more information.
