About serial ports
IBM Aptiva PCs have built-in external serial ports
already installed in the computer. The connectors for
these ports are located on the back of your computer.
These ports can be used to connect a serial mouse,
serial printer or other serial devices and to transfer data
between computers.
Serial ports A and B support these addresses and
interrupts.
Address

3E8

Conflicts may arise if you add adapter cards with serial
ports or if you change the address settings on your
modem. You can resolve most of these conflicts by
using the Setup Utility to change serial port addresses.
See "Working with the Setup Utility" on page 69 for
more information.
