===== Brief =====

GET AND SET EXTENDED CONTROL-BREAK CHECKING STATE
===== Family API =====


===== Input =====

        AX = 3302h
        DL = new state (00h for OFF, 01h for ON)

===== Notes =====

  this function does not use any of the DOS-internal stacks and may thus
          be called at any time; one possible use is modifying Control-Break
          checking from within an interrupt handler or TSR
        not supported by DR DOS through version 6.0 (error code 01h);
          newly-supported by Novell DOS 7
