+
+  Description:  Contains headers of a Q.921 protocol on top of the Comet 
+                Driver.
+
+                Most of the work required to execute a Q.921 protocol is 
+                taken care of by the Comet ship and it's driver. This layer
+                will simply configure and make use of these features to 
+                complete a Q.921 implementation.
+
+  Note:         This header file is the only include file that should be 
+                acessed by users of the Q.921 stack.
+
+  Interface:    The Q.921 stack contains 2 layers. 
+
+                -   One interface layer.
+                -   One driver layer.
+
+                The interface layer contains the interface functions required 
+                for a layer 3 stack to be able to send and receive messages.
+
+                The driver layer will simply feed bytes into the ship as
+                required and queue messages received out from the ship.
+
+                Q921TimeTick        The Q.921 like any other blackbox 
+                                    modules contains no thread by it's own
+                                    and must therefore be called regularly 
+                                    by an external 'thread' to do maintenance
+                                    etc.
+
+                Q921Rx32            Receive message from layer 3. Called by
+                                    the layer 3 stack to send a message.
+
+                Q921Tx23            Send a message to layer 3. 
+
+                OnQ921Error         Function called every if an error is 
+                                    deteceted.
+
+                OnQ921Log           Function called if logging is active.
