Serial Ports
The built-in 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. They use the
following system I/O addresses:
Port Configuration I/O Address
COM1 3F8h
COM2 2F8h
COM3/COM4 3E8h/2E8h
Connecting the Serial Ports
Two DB-9P serial port cables are provided with the
motherboard. They are mounted on a card-edge bracket
along with the PS/2 mouse cable. The upper serial port
cable should be used for the COM 1 primary serial port;
connect it to Connector COM 1 on the motherboard.
The lower serial port cable should be used for the COM
2 secondary serial port; connect it to Connector COM 2
on the motherboard. Make sure the colored stripes on
the ribbon cables align with pin 1 of Connectors COM 1
and COM 2. Mount the card-edge bracket to the system
chassis.
