By: Morton F. Kaplon CIM:73457,437 or emkay@fast.net
The program C-A-D.EXE toggles the Ctrl-Alt-Del Key sequence between
ENABLED (the system default) and DISABLED. When Ctrl-Alt-Del is in
the DISABLED state that key sequence does nothing. In that state the
OS/2 HotKey Alt-Home, which toggles DOS sessions between a Windowed
and FullScreen State is also DISABLED. This is a side effect. In the
DISABLED state you cannot accidentally REBOOT by hitting the
Ctrl-Alt-Del key sequence.
C-A-D.EXE is designed to be used in conjunction with the enclosed
program CADMEM.EXE. CADMEM.EXE should be loaded first. This program
merely establishes a Shared Memory Area that C-A-D.EXE uses to store
the Toggled State of Ctrl-Alt-Del.
C-A-D when called will read that State, give you a message informing
you whether Ctrl-Alt-Del is ENABLED or DISABLED and offering you
the option to change that State, and if it is changed it will so
inform you.
The reason for using CADMEM.EXE is that there is no way to change
environment variables globally, otherwise the Environment would
be used to store the Toggled State.
CADMEM.EXE should not be unloaded if you wish to use C-A-D.EXE in
its intelligent mode.
CADMEM can be unloaded by using Ctrl-Esc to activate the Task List,
Higlight the title CADMEM and press the <Del> key. CADMEM.EXE will
be unloaded.
IF you do not load CADMEM.EXE first, C-A-D.EXE will offer you the
option of Toggling the State. In this case it is your responsibility
to know the Toggled State.
The toggling action is accomplished by using the function:
DosDevIOCtl with Category 4(Keyboard), Function 56Hex which allows
setting of Session Hot Keys.
