The device parameters provide offline identification information based on DTM type information intended for identification. This data may provide values or regular expressions to define ranges of supported values.

In the call to IDtmInformation.GetDeviceIdentInfo() a protocol must be specified. The first entry from the list of INetworkData.ActiveProtocols shall be used.

GetDeviceIdentInfo() may return a list of DeviceIdentInfo where the first entry is used for the parameters as defined below. Exposing the remaining list entries is implementation specific.
