Do This First
Please read the following tips carefully before attempting to
install your new modem.

NSTALLATION
Because Windows 3.1 and 3.11 are not Plug-N-Play operating systems, it is
suggested that you do not rely on the Plug-N-Play capabilities of your com-
puter to automatically configure the modem. Instead, manually select the COM
Port and IRQ setting by changing the jumpers. The jumper setting definitions
can be found in the
Installing The Modem
section under the heading
Jumper
Settings
. It is recommended that you disable an existing COM Port that you
are not using, like COM 2, and set the modems jumpers for COM 2 -IRQ 3.
This will avoid many of the pitfalls associated with installing a modem in
Windows 3.1X. If you cannot disable an existing COM Port, then you must
use COM Ports 3 or 4 and select an interrupt that does not cause a conflict
with another device. If you do not know the available interrupts on your sys-
tem, you will have to use trial-and-error to get the modem properly config-
ured.
To disable one of your computers existing COM Ports, you need to enter
your System BIOS Setup routine (read your Computers User Manual for
instructions on how to invoke the BIOS Setup). [If you have a seperate I/O
card, use the cards jumbers to disable a COM Port]. Once inside the BIOS
Setup, look for a section called
Integrated Peripherals
. Locate the entry for
COM 2 or COM Port B and disable it. Save your settings before exiting.
Install your modem into the computer and start Windows 3.1 or 3.11.
Since you have manually selected the COM Port and IRQ settings of the
modem using the jumpers, you will have to manually assign the IRQ and
COM Port address in Windows 3.1X to the same settings as the modem. In
Windows 3.1X
Program Manager
, double-click on
Main
and then on
Con-
trol Panel
. Double-click on
Ports
. Select the COM Port your modem is us-
ing by clicking once on the icon for that port. Click on
Settings
and then on
Advanced
. The COM Port is represented as an I/O address in hexadecimal
format. Select
3F8
for COM 1,
2F8
for COM 2,
3E8
for COM 3, or
2E8
for
COM 4 depending on which COM Port you selected your modem for. The
IRQ setting will be selected by setting the IRQ box to the appropriate num-
ber. If you have set your modem to COM 2, then you would set the IRQ to 3.
If you had chosen COM 3, then you would have set the IRQ jumper on the
modem to an available IRQ setting, one that did not interfere with another
device. You will need to set the Windows IRQ setting to this same number.
After you have configured Windows 3.1X, close Windows and reboot your
system. Install your communications software.
