SUMMARY
The Microsoft Windows NT Hardware Compatibility List (HCL) lists a number of modems supported for use with Windows NT Remote Access Services (RAS). Modems not listed on the HCL, however, work with RAS if you supply RAS with the command strings required by the modem. You can supply RAS with these command strings by appending a new section for your modem to the %SystemRoot%\SYSTEM32\RAS\MODEM.INF file.

Some modem vendors have created MODEM.INF sections for their unsupported modems to operate with RAS or to update the MODEM.INF for their supported modems. The table below lists third-party vendors, their phone numbers, and the names of files containing MODEM.INF sections.

NOTE: If you plan to use an unsupported modem with Windows for Workgroups RAS, request a Windows for Workgroups RAS MODEM.INF section from the modem vendor. If the vendor does not have one, you may be able to use a Windows NT RAS MODEM.INF file section by removing the following lines wherever they appear in the MODEM.INF file section:
