Modifying SmpData.inf
The Driver Development Kit (DDK) included a sample data modem file called SmpData.inf. You can create your modem INF file by modifying the SmpData.inf file.
The SmpData.inf file has the following characteristics:
Installs modems made by a single manufacturer.
Installs either a PCMCIA Data Fax or an External Data Fax Modem.
Uses multiple add-registry-sections, which can be easily modified to support additional modems.
Your modem INF file, however, can install any number of modems from multiple manufacturers and can contain any number of add-registry-sections.
