Serial (COM) Ports
COM 1
The system board is equipped with an onboard serial port (COM
1). It is also equipped with a 9-pin connector (COM 2). These serial
por ts are RS-232 asynchronous communication por ts with
16C550A-compatible UARTs that can be used with modems, serial
printers, remote display terminals, and other serial devices.
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 serial port cable to COM 2. Make sure the
colored stripe on the ribbon cable is aligned with pin 1 of COM 2. .
BIOS Setting
Configure the serial ports in the Integrated Peripherals submenu
(“Super IO Device” section) of the BIOS. Refer to chapter 3 for
