4-16 Netopia ISDN Modem User’s Guide
Installing the Windows NT modem driver
If you are using Windows NT, you need to install a modem driver for
your ISDN modem before you can place calls. Follow the
instructions below to install the Windows NT modem driver.
Note: The Remote Access Service (RAS) software must be installed
on your system before you install the Windows NT modem driver.
You use RAS to install the modem driver. See your Windows NT
documentation for information on installing RAS.
Installing the Windows NT modem driver
1. Start up the File Manager.
2. Locate the Windows NT MODEM.INF file in the
%SYSTEMROOT%\SYSTEM32\RAS directory.
For example, if your root directory is named WINDOWS and is
located on the C:\ drive, the Windows NT MODEM.INF file is in
the following directory:
C:\WINDOWS\SYSTEM32\RAS
3. Use the Rename command in the File menu to change the
name of the MODEM.INF file to MODEM.ORG.
4. Locate the MODEM.INF file in the directory in which you
installed the Netopia configuration files. (By default, the file is
installed in the C:\NETOPIA directory.)
5. Copy the Netopia ISDN Modem file, MODEM.INF, from the Neto-
pia directory to the same directory as the MODEM.ORG file.
(You are replacing the Windows NT MODEM.INF file with the
Netopia MODEM.INF file.)
6. Open the Main folder in the Program Manager and double-click
the Control Panel icon. The Control Panel folder opens.
