Configuring DOS and Windows 3.1X
Note: Not all communications programs are supported under DOS due to PCI
IRQ requirements. Unless your application can support IRQ 9 or above
and can address nonstandard COM Port addresses, it may not be able to
support this modem.
Step 1 After you have installed the modem into your machine, turn on the power
and allow the system to boot normally.
Step 2 After the system has loaded, insert the installation CD-ROM. At the
prompt, type “D:PMDMCFG.EXE” and press enter. (You may need to
change the drive letter from D to the letter of your CD-ROM drive.
Step 3 A message similar to the one shown below will be displayed. (Actual
values will change from system to system)
Found V.90 PCI Data/Fax Modem
-----------------------------
I/O Port: FC00
IRQ#: 11
Step 4 Write down the IRQ Number and Base I/O Address that have been
assigned to the modem. If the default Base I/O Address is greater than
7900, you will need to add a statement to your autoexec.bat file to preset
this address to a specific value. Go to Step 5. If your default address is
below 7900, go to Step 6. Before you proceed, copy the PMDMCFG.EXE
file to the root directory of your default hard drive (usually the C:> drive).
Step 5 If the default Base I/O Address in Step 3 was greater than 7900 (If less
than or equal to 7900, do not perform this procedure.), modify your
autoexec.bat file to preset the Base I/O Address of the modem to a specific
value by adding the following statement:
C:\PMDMCFG /P7900
Step 6 Use the default I/O Port Address (or 7900 if you modified your
autoexec.bat file) and the IRQ Number you recorded in Step 4 to set up
your DOS applications. You may also need to assign an unused COM
Port to the modem. The preferred COM Port setting is COM4.
Step 7 After you nave set up your applications to use the modem, you will need
to issue an AT Command to configure the modem to use the PSTN (Public
Switched Telephone Network) of your country. The modem can be
configured for: Canada, Japan, and the United States.
