- Press Alt left-Shift Z keys to lock keyboard and blank screen
immediately. This version also locks the mouse if your mouse

PROGRAM DESCRIPTION
Protect monitors from phosphors burning caused by displaying
the same image for long periods of time. Works with MDA, CGA,
EGA and VGA monitors.
Blanks the screen after set number of minutes of KEYBOARD or
MOUSE inactivity. Press any key or move mouse to restore screen.
The key pressed to reactivate the screen is removed and not
passed through to the program currently running. Instantly
lockout keyboard and blank screen by pressing Alt LeftShift Z
keys. Unlock keyboard and restore screen by pressing Alt
LeftShift Z keys again. The number of minutes to delay before
blanking screen can be set from 0 to 60 minutes. Using a
parameter of 0 minutes disables the blank after a period of
inactivity feature of CRTSAVER.
CRTSCNFG.EXE is included in the registered version. It allows
you to change the following in CRTSAVER:
- The letter key (A-Z) used as part of the hotkey
combination for the instant blank and keyboard lock
function.
- The default delay used if no delay value is included
on the command line.
SYSTEM REQUIREMENTS
VGA, EGA, CGA or MDA(mono) video display
Note - not tested on MCGA.
- CRTSAVER is NOT compatible with HGC (Hercules Graphics
Card) and will not load if a HGC adapter is detected.
<optional> mouse or trackball with Microsoft(tm) or
Mouse Systems(tm) compatible driver installed.
INSTALLATION AND USAGE -
CRTSAVER is a memory resident program using approximately 1K
of memory. DO NOT load CRTSAVER from a program that allows you
to run other programs (shell to DOS or shells to a command
line). When you first load (run) CRTSAVER it must be from a
batch file (autoexec.bat when you boot) or from the command line
only. Once a copy of CRTSAVER is resident in memory, you can run
it again at any time (from DOS shell, batch file, etc.) with a
new minute parameter. It searches memory for the resident copy
of CRTSAVER and installs the new delay.
Copy the file CRTSAVER.COM to your hard drive or boot disk.
To automatically load CRTSAVER each time you start (boot) the
computer, edit your AUTOEXEC.BAT file to included "CRTSAVER" on
a line some where near the end of the autoexec.bat file. Use a
text editor or word processor to enter the line of text in the
autoexec.bat file. If you have other TSR (memory resident)
program that load in the autoexec.bat file, CRTSAVER should be
the last one loaded. This is to insure that CRTSAVER will
intercept the keyboard interrupt first, so it can successfully
lock the keyboard.
Note: You should only edit your AUTOEXEC.BAT file in a non-
document mode (also known as ASCII or text mode). Most editors
or word processors provide a way to edit files like
autoexec.bat. Check your editor or word processor manual if you
are not sure. If you are not familiar with your autoexec.bat
file or how to edit it, read your DOS manual for more
information.
Use command line parameters to select a timeout delay.
Parameter 0 - 60 (minutes of inactivity before blanking screen)
Examples of usage in autoexec.bat:
CRTSAVER 10
If you copied CRTSAVER to a directory other than the root then
you would need to include a path when loading.
c:\dos\crtsaver 25
c:\util\crtsaver 8
c:\util\crtsaver (default - 4 min.)
crtsaver 0
A parameter of 0 minutes disables the blanking after a period
of inactivity feature of CRTSAVER. You will still be able to
blank the screen and lock the keyboard by pressing the hotkey -
Alt left-Shift Z.
To remove CRTSAVER from memory:
crtsaver r
(or) crtsaver -r
(or) crtsaver /r
To display help text:
crtsaver ?
(or) crtsaver -?
(or) crtsaver /?
(or) crtsaver h
(or) crtsaver -h
(or) crtsaver /h
(or) crtsaver help
WINDOWS 3.x(tm)
CRTSAVER version 1.6 does not need to be removed or disabled
before running Microsoft Windows(tm) 3.x. CRTSAVER automatically
disables itself when Windows is running.
Windows takes over the keyboard interrupt and bypasses the
normal keyboard routines. Because of this most DOS screen savers
can not restore the screen if the screen blanks while in
Windows. Usually the only option, when the screen cannot be
restored, is to reboot. CRTSAVER does not blank the screen when
in the Windows desktop or a Windows program.
When running regular DOS programs or at a DOS prompt under
Windows **
** Windows running in standard or real modes - screen
blanking function is active, Alt left-Shift Z keys does
not disable keyboard or mouse, only blanks screen.
** Windows running in 386 enhanced mode - Alt left-Shift Z
keys blank screen, otherwise screen blanking function is
turn off. Pressing Alt left-Shift Z key combination turns
screen off, DOS mouse driver off and partially disables
keyboard. Windows maintains control of the keyboard
allowing Ctrl Alt Del(reboot) and Alt Esc or Ctrl Esc
(return to desktop, switch tasks etc.). Press the Alt
left-Shift Z key combination again to turn screen on,
restore DOS mouse driver and keyboard.
LOCK KEYBOARD and MOUSE - BLANK SCREEN
Hold down the Alt, left-Shift keys and press the Z key at the
same time to instantly lockout keyboard and blank screen. Unlock
keyboard and restore screen by pressing Alt left-Shift Z keys
again.
This version also turns the mouse driver off/on if the driver
supports this function (if the mouse is Microsoft Windows
3.0(tm) compatible then it should support this function). The
driver software that came with older mice does not support this
function and the mouse will remain active. So, if you lock the
keyboard and blank the screen while running a program that makes
use of a mouse, someone might still be able to mess with the
program. Also if you are using my program ARRMOUSE and your
mouse driver does not support this function, ARRMOUSE will
remain active.
MOUSE SUPPORT
A mouse is optional, CRTSAVER checks for the presence of a
mouse driver and works fine if no mouse or mouse driver is
installed.
Note - For CRTSAVER to check for mouse inactivity before
blanking the screen, a Microsoft(tm) or Mouse Systems(tm)
compatible mouse driver MUST BE INSTALLED. Make sure to load
CRTSAVER after your mouse driver.
PERSONAL NOTE
I have tried several "screen savers" and none seemed to fit
my needs. The one that was on the disk that came with my VGA
card would lock my machine up every so often. I like a delay of
about 4 minutes. When using other screen savers and running
programs that use a mouse, the screen would blank right in the
middle doing something. I could easily press a key and restored
screen, but it was irritating. So I created CRTSAVER for my own
use. I don't need the keyboard locking feature, but thought it
would be useful in an office environment or where other have
access to your computer. CRTSAVER works great on my machine and
I hope it works as well for you.
