Communication Settings; Changing Modem Addresses - IBM Aptiva Series Handbook

If your computer came with a fax software already installed,
use the fax software documentation included in your
computer package or the fax software online help for
additional information.

Communication settings

For IBM Aptiva PCs that came with modems installed, the
modems are preset to
COM1 assigned with the address
. The modem address in your
3F8 and IRQ4
communications software must match the address setting of
your modem.
The addresses and interrupts supported by your computer
are:
COM # Address
COM1 3F8
COM2 2F8
COM3 3E8
COM4 2E8

Changing modem addresses

There are times when you may need to change the default
address of your modem. You may use the Windows 95
Device Manager to do this. See the section "Resolving
resource conflicts" on page 6-3. This section contains
information to help you avoid potential conflicts when you
need to change resources used by adapter cards.
