Serial Ports (COM1 & COM2 & COM34)

The PCA-6743 offers four serial ports, COMD1 as COM1 (RS-232 (VE SKU)/ RS-

232/RS-422/RS-485 (F SKU) on real I/O) and COM2 as COM2 (RS-232(VE SKU)/

RS-232/RS-422/RS-485 (F SKU) on one 2.54mm pitch wafer box) and COM34 as

COM3, COM4 (2*RS-232 (F SKU) on one 2.0mm pitch wafer box). These ports can

connect to serial devices, such as a mouse or a printer, or to a communications net-

work.

The IRQ and address ranges for both ports are fixed. However, if you want to disable

the port or change these parameters later, you can do this in the system BIOS setup.

Different devices implement the RS-232 standard in different ways. If you are having

problems with a serial device, be sure to check the pin assignments for the connec-

tor.
