The system board is equipped with an onboard serial port (CN6 -
Teal/Turquoise) for COM 1 and a 9-pin connector at location J2 for
COM 2. These 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 serial port for COM 2 may be mounted on a card-edge
bracket. Install the card-edge bracket to the system chassis then
insert the cable connector to J2. Make sure the colored stripe on the
ribbon cable is aligned with pin 1 of J2.
