   T_DRV_SIGNAL - driver signal identification
 
   The type defines the signal information data used to identify a signal. 
   This data type is used to define and to report a signal. A signal is 
   defined by a process calling the driver function drv_SetSignal. An 
   event is signalled by driver by calling the pre-defined signal call-
   back function.

   T_DRV_CB_FUNC - driver signal device control block
  
   This type defines a call-back function used to signal driver events,
   e.g. driver is ready to accept data. The driver calls the signal
   call-back function when a specific event occurs and the driver has
   been instructed to signal the event to a specific process. A process
   can set or reset event signalling by calling one of the driver 
   functions drv_SetSignal or drv_ResetSignal. Event signalling can only
   be performed when a call-back function has been installed at driver
   initialization.
