<pre><b>INT 21 - DOS 2+ - EXTENDED BREAK CHECKING</b>

	AH = 33h
	AL = subfunction
	    00h get current extended break state
		Return: DL = current state, 00h = off, 01h = on
	    01h set state of extended ^C/^Break checking
		DL = new state
		    00h off, check only on character I/O functions
		    01h on, check on all DOS functions
		Return: (Novell DOS 7) DL = old state of extended Break checks
Note:	under DOS 3.1+ and DR DOS, this function does not use any of the
	  DOS-internal stacks and may thus be called at any time
