oWin:commNotify( <nDevice>, <nStatus> ) -> NIL

------------------------------------------------------------------------------

 PARAMETER:

   <nDevice>   communication-device ID, specifies the identifier of the 
               communication device that is posting the notification message. 

   <nStatus>   notification-status flag, Indicating the type of COM Event
               that has happened. It may be one or more of the following 
               flags: 

                CN_EVENT    Indicates that an event has occurred that was 
                            enabled in the event word of the communication 
                            device. This event was enabled by a call to the 
                            SetCommEventMask function. The application should 
                            call the GetCommEventMask function to determine 
                            which event occurred and to clear the event. 

                CN_RECEIVE  Indicates that at least cbWriteNotify bytes are 
                            in the input queue. The cbWriteNotify parameter 
                            is a parameter of the EnableCommNotification 
                            function. 

                CN_TRANSMIT Indicates that fewer than cbOutQueue bytes are in 
                            the output queue waiting to be transmitted. 
                            The cbOutQueue parameter is a parameter of the 
                            EnableCommNotification function. 


 DESCRIPTION:

  The WM_COMMNOTIFY message is posted by a communication device driver
  whenever a COM port event occurs. The message indicates the status of a 
  window's input or output queue. This Method is the receiver of this
  message, and it will eval the bCommNotify CodeBlock if it is provided.
