DIMMER                  Douglas Boling and Jeff Prosise
Software VGA brightness control		    Version 1.0
-------------------------------------------------------

Purpose
-------
To provide software control of VGA monitor brightness
interactively from the keyboard, through parameters
entered on the command line, or at a specified
interval after the last keystroke.

Format
------

    DIMMER [[+|-]adj] [/D time [+|-]adj] [/V[+|-]] [/U]

Remarks
-------
Entered without any of its optional parameters, DIMMER
uses the Alt-Up-Arrow and Alt-Down-Arrow keys to
increase or decrease screen brightness. The original
intensity level can be restored at any time by
pressing Alt-Home. DIMMER is a memory-resident program
and can be uninstalled by being run with the /U switch.

The adj parameter accepts integer values from +63 to
-63. Although relative to the intensity level in
effect when the program loads, a value of -63 will
completely blank the screen and +63 will wash out
almost all colours. The time parameter sets the number
of minutes (up to 65,534) to allow after the last
keystroke. Used in conjunction with the optional /D
switch and an adj value (usually -63), the time
parameter is normally used when it is desired to blank
the screen after a specified period of keyboard
inactivity. Any subsequent keypress will restore the
screen to its original level, but as this keystroke
will be fed to the application, it is safest to hit an
unaccompanied Ctrl, Alt, or Shift key. Once active,
the screen-saver option can be cancelled by entering
DIMMER /D 0.

With applications that do not write directly to the
video BIOS, a blanked screen can be automatically
restored when the program attempts to update the
display. This is accomplished by using the optional
/V (or V+) switch. By default, DIMMER restores the
intensity level only when a keystroke is entered,
which is equivalent to running the program with a /V-
command-line switch.
