DOS 3.x+ internal - GET AND SET EXTENDED CONTROL-BREAK CHECKING STATE

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
