IBM Aptiva E40/E24
(250-0467/8)           Serial Port Addresses          Faxback Doc. # 40717

IBM Aptiva PCs 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.

Address       Windows 95     Interrupt     Default

3F8           COM1           IRQ4          Modem
3E8           COM3           IRQ4          Serial Port A
2F8           COM2           IRQ3          Serial Port B
2E8           COM4           IRQ3

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 95.  You can resolve most of these conflicts by
using the Setup Utility to change serial port addresses.
