* 
* 
*   ON AN INPUT REQUEST THE DEVICE SOFTWARE STATUS IS SET 
*   'BUSY' UNTIL THE INPUT INTERRUPT IS TAKEN CARE OF 
* 
* 
*   AT POWER UP RUNNING READ REQUEST IS COMPLETED WITH -2 
*   IN CONTROL WORD.IF NO RUNNING READ REQUEST,POWER UP 
*   IS INDICATED AND NEXT READ REQUEST IS TERMINATED WITH 
*   -2 IN CONTROL WORD
* 
* 
*   ON AN OUTPUT REQUEST THE DEVICE SOFTWARE STATUS IS SET
*   'READY' IMMEDIATELY, SINCE THE OUTPUT DOES NOT REQUIRE
*   AN INTERRUPT.
