Obtaining and Using Unimodem ID Strings

A Unimodem ID, also known as a legacy ID, is generated by interrogating the modem with standard modem ATI commands and is commonly found in all modem types. You want to obtain the unimodem ID from your modem and put it into your INF file to insure that any real-mode drivers your modem requires are installed.

Unimodem ID strings can be obtained in either of two ways:

• Attempt to autodetect the modem. A file named MODEMDET.TXT will be generated in the Windows subdirectory. The Unimodem ID is found near the end of that file. When you decide where you want to place the Unimodem ID string in your INF file, then you can copy the string from MODEMDET.TXT and paste it into your INF file.
• The MODEMID.EXE tool, which is included in the MDK, can also be used to generate the same information. MODEMID.EXE has the advantage that it will operate in non-Windows 95 environments such as Windows NT and Windows 3.1. MODEMID.EXE can also be used to obtain Unimodem ID strings from all types of modems, including PCMCIA modems.

An example Unimodem ID string is
