COM (Serial) Ports
COM 1
The pin function of the COM ports will vary according to JP8/JP9/JP10/JP11’s set-
ting. Refer to “RS232/RS422/RS485 Select” in this chapter for more information.
The serial ports are 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 the 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 Advanced menu (“Super IO Configuration” sub-
menu) of the BIOS. Refer to chapter 3 for more information.
