2.5.4 Serial Ports

The system board is equipped with an onboard serial port (Teal/
Turquoise) for COM 1 and a 9-pin connector at location J7 for
COM 2. These ports are RS-232C asynchronous communication
ports with 16C550A-compatible UARTs that can be used with mo-
dems, serial printers, remote display terminals, and other serial de-
vices.
One card-edge bracket, mounted with a serial port cable, will be
provided as an option. If you want to use the COM 2 serial port,
connect the serial por t cable to connector J7. Make sure the
colored stripe on the ribbon cable is aligned with pin 1 of connec-
tor J7. Mount the card-edge bracket to the system chassis.
BIOS Setting
Select the serial ports' I/O address in the Integrated Peripherals
submenu ("Super IO Device" section) of the BIOS. Refer to chapter
