The CPC-2245N offers two serial ports: COM1 and COM2, both in
RS- 232. These ports let you connect to serial devices (a mouse,
printers, etc.) or a communication network.

You can select the address for each port (For example, 3F8H
[COM1], 2F8H [COM2]) or disable it, using the BIOS Advanced
Setup program. 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.

The IRQ and address range for both ports are fixed. However, if
you wish to disable the port or change these parameters later, you
can do this in the system BIOS setup. The table below shows the
settings for the CPC-2245N board's ports:
