Implement DLogicalChannel by processing a message from user-side.
This function is called in the context of the thread which is using
the handle.

@param a1 First call-specific argument passed to DoControl.
@param a2 Second call-specific argument passed to DoControl.
@return Symbian OS error code. This is used to complete the
user-side TRequestStatus object.
