COM 2
The serial ports are RS-232C asynchronous communication ports
with 16C550A-compatible UARTs that can be used with modems,
serial printers, remote display terminals, and other serial devices.
The system board is equipped with an onboard serial port (CN6
- Teal/Turquoise) for COM 1 and three 9-pin connectors at loca-
tions J17, J18 and J19 for COM 2, COM 3 and COM 4 respec-
tively.
The serial por ts for COM 2, COM 3 and COM 4 may be
mounted on a card-edge bracket. Install the card-edge bracket to
the system chassis then insert the cable connector to J17, J18 or
J19. Make sure the colored stripe on the ribbon cable is aligned
with pin 1 of J17, J18 or J19.
BIOS Setting
Select the serial ports’ I/O address in the Integrated Peripherals
submenu (“Onboard Super IO Device” field) of the BIOS. Refer to
