INT 1B - KEYBOARD - CONTROL-BREAK HANDLER

Desc:	this interrupt is automatically called when INT 09 determines that
	  Control-Break has been pressed
Note:	normally points to a short routine in DOS which sets the Ctrl-C flag,
	  thus invoking INT 23h the next time DOS checks for Ctrl-C.
SeeAlso: INT 23,MEM 0040h:0071h
