Int 21 Fn 33 - DOS 2+ - Extended Break Checking [D]
AH = 33h
AL = subfunction
00h get current extended break state
Return: DL = current state, 00h = off, 01h = on
01h set state of extended Break checking
DL = 00h off, check only on character I/O functions
01h on, check on all DOS functions
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
