Serial ports

The SBC-455 offers two RS-232 serial ports. You can select or disable the address for each port with the BIOS Peripheral Setup program.

The card mounting bracket holds COM A, the DB-9 serial port connector for the first port. The parallel port and serial port adapter kit (supplied with the card) holds COM B, the DB-9 connector for the second port. This lets you connect and discon- nect the cables after you install the card. The following sections tell how to make RS-232 connections.
