Modifying the Version Section of SmpData.inf
In most cases, it should not be necessary to modify the INF Version section of SmpData.inf.
The Version section of a modem INF file has the following modem-specific characteristics:
Class
The Version section should contain a Class entry so that someone reading the file can easily determine that the file installs a modem.
The Class entry for modems is always Modem.
ClassGuid
All devices are assigned to a device setup class, identified by a GUID, so the class installer can identify them.
The Version section of the modem INF must contain a ClassGuid directive:
| Modem Class | ClassGuid |
|---|---|
Modem |
{4D36E96D-E325-11CE-BFC1-08002BE10318} |
Signature
The Signature directive in modem INF files is generally set to $WINDOWS NT$.
For more information about the version section, see INF Version Section.
Example Version Section
The following is an example of a Version section for an INF file that installs a modem:
[Version]
Signature="$WINDOWS NT$"
Class=Modem
ClassGUID={4D36E96D-E325-11CE-BFC1-08002BE10318}
Provider=%CompanyName%
DriverVer=11/15/2002,5.01.3714.1
Note that the Provider directive indicates who developed the INF file -- not who developed the component that is installed by the INF file.
