Serial port addresses
IBM computers have a built-in external serial port already installed in the computer.
The connector for this port is located at the back of your computer. This port can be
used to connect a serial mouse, serial printer, or other serial device and to transfer
data between computers.
The built-in serial port supports the following addresses and interrupts.
Conflicts may arise if you add adapter cards with serial ports or if you change the
address settings on your modem if you are using an operating system other than
Windows. You can resolve most of these conflicts by using Setup or the Windows
Device Manager to change serial port addresses. See “Serial Port Setup” on page
4-9 or “Resolving resource conflicts” on page 5-4 for more information.
