The Novell Internet Access Server 4.1 routing software provides a Windows-based utility that enables you to create a customized modem description file. To create, edit, or install a modem description file, start the WMDMMGR utility the same way you would start any Windows 3.1, Windows 95, or Windows NT utility. This utility can be run only at a Windows workstation and cannot be run from the DOS prompt.

WMDMMGR is located in the SYS:\SYSTEM\UTILS directory on your server. Three sample modem description files, with an .MDC extension, are provided in the SYS:\SYSTEM directory of your router. These files contain modem scripts that are certified by the Novell Labs^TM group (NIASCERT.MDC), as well as scripts for commonly used modems (NIASMDM1.MDC and NIASMDM2.MDC). You can modify these modem scripts to meet your requirements, although this is not recommended for scripts in the NIASCERT.MDC file.

To create a new modem description file, select New from the File menu. To modify an existing login script, select Open from the File menu. After editing the modem description file as described in the online help, save your changes by selecting Save or Save As from the File menu. To edit existing files, copy the files to the SYS:\SYSTEM directory. If you have any problems editing or using existing modem description files, refer to Novell Internet Access Server 4.1 Management and Optimization.

The remaining sections in this chapter provide the background information you need to understand the operation of modem description files.
