I am having a problem regarding Control-C (Control-Break).
I have a memory-resident program which intercepts the
INT 23h vector, which I believe is the address that gets
conrol when a control-c is detected.  However, when I
interrupt a sample program with a control-break, my
resident routine never gets control.  What am I missing?
The sample program that I interrupt follows:

CODE_SEG	segment		para public 'code'
		assume		cs:CODE_SEG,ds:CODE_SEG,es:CODE_SEG
msg1		db		'OK',0Dh,0Ah,'$'
p0:		push		ds
		xor		ax,ax
		push		ax
		mov		ax,CODE_SEG
		mov		ds,ax
p1:
		xor		ax,ax
		int       	16h
		lea		dx,msg1
		int		21h
		jmp		p1
CODE_SEG	ends
		end	p0

Thanks for any help.
