	AX = BE00h
Return: AL = FFh if installed
Program: REDVIEW is a public-domain TSR by Alexandr Novy and Petr Horak which
	  copies data sent to standard output to standard error when the
	  former has been redirected to a file, thus allowing the data to
	  be seen on the screen at the same time it is captured in a file
