You may be able to make RAS 1.1a, RAS for Windows for Workgroups 3.11, and RAS for Windows NT version 3.1 work with an unsupported modem (for example, a V.fc,V.fast, or V.34 modem, which is unsupported in these versions). If you want to use a V.fc, V.fast, or V.34 modem, it is recommended that you use a RAS client computer that has a 486 processor or later, and a serial port that has a 16550 UART chip or later. If problems occur, configure your modem to use V.32 bis.
The easiest way to get an unsupported modem supported under RAS for Windows for Workgroups 3.11 or RAS for Windows NT 3.1 is to obtain a modem that is supported in RAS for Windows NT 3.5 or 3.51. The following procedure assumes that you have a modem that is supported in Windows NT 3.5 or 3.51. If your modem is not supported in Windows NT 3.5 or 3.51 or you have RAS 1.1a, skip the following procedure, but read the rest of this chapter, and then follow the instructions in the Help topic "Modifying MODEM.INF."
1. From the RAS for Windows NT 3.5 or 3.51 MODEM.INF file, copy the section that applies to your modem.
2. Load MODEM.INF into a text editor and append the copied section to the RAS for Windows for Workgroups 3.11 or Windows NT 3.1 MODEM.INF file.
3. Remove the lines that start with the following words from the section you appended:
DETECT_STRING=
DETECT_RESPONSE=
Note
RAS modem autodetection is not supported in RAS for Windows for Workgroups 3.11 and RAS for Windows NT 3.1.
4. Save MODEM.INF, and then quit the text editor.
5. Restart your computer.
6. Depending on whether you have Windows NT 3.1 or Windows for Workgroups 3.11, continue with the following corresponding section.
1. Restart the RAS client software, and then choose Configure from the Setup menu.
2. Select your modem from the Device field, and then click OK.
RAS is now ready to use your modem.
1. Start Control Panel, and then choose the Network icon.
2. Select Remote Access Service from the list of Installed Network Software, and then click Configure.
3. In the Remote Access Setup dialog box, click Configure.
4. In the Attached Device box, select the modem name that corresponds to the section you just copied to Modem.inf, and then click OK.
RAS is now ready to use your modem.
