DESCRIPTION
       The  Datakit  interface	is  a stream directory containing a data and a control file.  Each write to the data file is a structured message.
       The first two bytes of the message are a 9-bit virtual circuit number, low order byte first.  The third byte is a control byte.	 The  rest
       are data bytes.	The data bytes are sent onto the Datakit virtual circuit, tagged as data, followed by the control byte, tagged as control.

       Messages  coming from Datakit are read from the data file in the same format.  A read terminates at the end of a message.  The largest pos-
       sible received message is 1024 + 3 bytes.
