	  any program by pressing the Alt key alone.
Notes:	The value in the key code word will be returned in AX by a call to
	  INT 16/AH=00h after the Alt key is pressed by itself
	ALTMENU may be disabled by setting the key code equal to 0000h

INT 2F - PCED v2.1 - INSTALLATION CHECK
	AX = 4800h
Return: AX = AACDh if installed

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.

2F4810 - INT 2F - DOS 5+ DOSKEY, PCED v2.1 - READ INPUT LINE FROM CONSOLE

INT 2F - DOS 5+ DOSKEY, PCED v2.1 - READ INPUT LINE FROM CONSOLE
	AX = 4810h
	DS:DX -> line buffer (see #01344 at INT 21/AH=0Ah)
Return: AX = 0000h if successful
Notes:	the first byte (length) of the buffer MUST be 80h, or MS-DOS's DOSKEY
	  chains to the previous handler; PCED and Novell DOS allow sizes
	  other than 80h
	if the user's input is a macro name, no text is placed in the buffer
	  even though AX=0000h on return; the program must immediately issue
	  this call again to retrieve the expansion of the macro.  Similarly,
	  if the user enters a special parameter such as $*, this call must
	  be repeated to retrieve the expansion; on the second call, DOSKEY
	  overwrites the macro name on the screen with its expansion.
	unlike DOSKEY, PCED expands all macros on the first call, so it is
	  not necessary to make two calls; since the buffer is not empty on
	  return, DOSKEY-aware programs will not make the second call
	DOSKEY chains if AL is not 00h or 10h on entry
	this function is supported by Novell DOS 7 DOSKEY

2FE337 - INT 2F - INT16.COM - INSTALLATION CHECK

INT 2F - INT16.COM - INSTALLATION CHECK
	AX = E337h
Return: AX = 0013h if installed
Program: INT16.COM is an INT16 keyboard BIOS replacement for
	  INT 16/AH=00h-02h,10h-12h (based on K3) written by Martin Gerdes
	  and published in c't 05/1990.

INT 2F - NDOS v4.0+ - KSTACK.COM - INSTALLATION CHECK
	AX = E44Fh
	BX = 0000h
Return: AX = 44EEh if installed
Program: NDOS is a version of 4DOS licensed to Symantec for inclusion in the
	  Norton Utilities
Note:	this function is also supported by ANSIPLUS v3.01+ and K3PLUS v6.20+,
	  which emulate the 4DOS and NDOS keystack

2FE44FBX0001 - INT 2F - NDOS v4.0+ - KSTACK.COM - PLACE KEYSTROKES INTO KEYSTACK

INT 2F - NDOS v4.0+ - KSTACK.COM - PLACE KEYSTROKES INTO KEYSTACK
	AX = E44Fh
	BX = 0001h
	CX = number of keystrokes (01h-FFh)
	DS:DX -> keystroke list (one word per keystroke)
Return: AX = status
	    0000h successful
	    nonzero failed
	BX,CX,DX destroyed
Notes:	the keystrokes are the exact values to return from subsequent calls to
	  INT 16 with AH=00h,01h,10h, or 11h, with the following exceptions:
		0000h causes subfunctions 01h and 11h to indicate an empty
		      keyboard buffer
		FFFFh is followed by a word indicating the number of clock
		      ticks to delay before the next faked keystroke
	v4.00 KSTACK overwrites any unread keystrokes from the previous
	  invocation, and does not range-check CX; it will overwrite memory
	  following the resident portion if CX is greater than 100h.
	this function is also supported by ANSIPLUS v3.01+ and K3PLUS v6.20+,
	  which emulate the 4DOS and NDOS keystack

Program: KS/KEYSTKCT.EXE is a key stacking utility (4DOS KEYSTACK.SYS
	  look-alike) by Martin Gerdes, published in c't 11/1991, which can be

66 - INT 66 - Newkey v5.4 - INSTALLATION VECTOR

INT 66 - Newkey v5.4 - INSTALLATION VECTOR
Return: immediately (IRET)
Program: Newkey is a shareware keyboard macro program by Frank A. Bell
InstallCheck:	test for the signature bytes FDh FCh FFh FEh at offset 03h in
	  the interrupt handlers segment
Range:	INT 60h to INT 67h, selected by scanning for highest unused vector
BUG:	the code obviously intends to use INT F0-FE, INT 70-77, and INT 68-6F
	  before falling back to INT 60-67, but only uses the last of these
	  ranges in v5.4
