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
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.
