Serial Ports (CN9: COM1; CN10: COM2)

The PCA-6175 offers two serial ports, CN1 as COM1 and CN2 as
COM2. These ports can connect to serial devices (such as a mouse,
printers, and so on) or to a communication network.

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 connector.
