CHAPTER 2 HARDWARE INSTALLATION

2.10 Serial Port Connectors: COM A & COM B

The mainboard has two 9-pin male DIN connectors for serial ports COM A

and COM B. These two ports are 16550A high speed communication ports

that send/receive 16 bytes FIFOs. You can attach a mouse or a modem cable

directly into these connectors.
