The DevSpecific access the device-specific functions.
Function DevSpecific(Data as VARIANT) As Boolean
A service provider can provide access to device-specific functions by defining parameters for use with this operation. Applications that want to make use of these device-specific extensions should consult the device-specific (vendor-specific) documentation that describes which extensions are defined. Typically, an application that relies on these device-specific extensions is not portable to work with other service-provider environments.
