<pre><b>INT 21 - DOS 3.x+ internal - GET AND SET EXTENDED CONTROL-BREAK CHECKING STATE</b>

	AX = 3302h
	DL = new state (00h for OFF, 01h for ON)
Return: DL = old state of extended BREAK checking
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
