AT Command Extension Module (Windows Embedded CE 6.0)

The AT Command Extension module enables you to extend the default command parsing and handling provided by the Audio Gateway Core Component.
Extensibility Considerations
By default, Microsoft implementation for the Hands-Free profile supports all of the mandatory and some optional AT commands, defined by the official Hands-Free Profile Specification. For more information about the supported commands, see Hands-Free Profile. You can use the extension module to implement an extensibility layer that handles custom parsing of AT commands and overrides the default responses to commands through custom handlers. Once the extensiblity layer is implemented, specify the name of the module in the registry by setting the BTAGExtModule value. For more information about this registry setting, see Audio Gateway Registry Settings.
To implement the extensibility layer, use the following functions.
