INT 2F - PCED v2.1 - INSTALLATION CHECK

	AX = 4800h
Return: AX = AACDh if installed
	    ES = segment of PCED kernel (PCED has multiple code segments)
Program: PCED v2.1 is a command line editor/history/macro facility by
	  Cove Software.  It is the commercial version of the freeware CED.
Notes:	DOSKEY also responds to this call if installed, returning AX=AA02h.
	unlike DOSKEY, PCED does *not* chain if AL contains an
	  unsupported function code.  It IRETs with all registers intact.
