I assumed that setting binary mode using DosDevIOCtl category 4 function 0x51

would work but I get an error 0x16 which is Unknown_Command. Here's my code:

----------------------------------------------------------------------------

/* Test for disabling keyboard Ctrl-C using emx 9.0a

	and os2.h and os2386.lib from DEVCON 7 Toolkit.



	I need to disable Ctrl-C for my OS/2 Native Forth Interpreter.

	Documentation in Control Program Guide and Reference is sparce

	but I assume that the DosDevIOCtl category 4, function 0x51 does

	what I want. But I can't get it to work. When I call it,

	I get error 0x16 which is Unknown Command. This happens both

	in a window and in full screen mode. Why?
