BLANKER
=======
What is Blanker?
================
Blanker is a utility for Windows 3.0 (or higher) that will blank your
screen when it is not in use. This helps prolong the useful life of
your monitor and also reduces the distraction of a colorful computer
screen when you aren't using it. As soon as you move your mouse or
press a key, the screen will return to what it looked like before
blanking.
Why does Blanker exist?
=======================
Yes ... there are a lot of screen savers available. Some are available
commercially, some as shareware and some as freeware. The more expensive
ones tend to provide you with lots of colorful and fanciful animation
on your screen. This is cute, but can get annoying after a while. Some
just do a basic job of blanking your screen, but don't always work properly.
So, Blanker was born out of frustration. I needed it for myself and wasn't
happy with any of the availble products.
What does Blanker do that makes it special?
===========================================
1) It operates invisibly. There is NO icon displayed when it is loaded.
The Windows Desktop is valuable "real-estate" and shouldn't be wasted
displaying the existence of basic utilities.
2) It is VERY small and takes up VERY little processor. A screen blanker
is a necessary utility. The fancy versions take up valuable resources.
Blanker is economical ... MUCH more so than most competing products.
3) It works better with DOS applications.
Very few screen savers seem to behave well with DOS apps. Many will
refuse to blank a DOS app if it is active (currently selected). Blanker
takes what I believe to be a more "liveable" approach -- The default
option will NOT blank a DOS session that is running in full-screen mode.
But, it will still blank normally if a DOS app is currently active while
in Windows. (You can choose to blank full-screen DOS sessions as an
option if you are running Windows in 386-Enhanced mode). Unlike
some of the fancy commercial screen savers, Blanker does not include
a DOS-based TSR or a device driver to blank DOS sessions. While
this is nice, it adds greatly to the likelihood that your screen
saver will somehow affect your system negatively.
4) It includes an option which allows "instant blanking" of your screen.
5) It is FREE!!! Use it and abuse it and hopefully enjoy it.
How do I use Blanker?
=====================
BLANKER.EXE can exist anywhere you wish. If you don't care, just put it
in your default Windows directory (usually C:\WINDOWS).
The file, BLANKER.INI does not have to be present. However, if you use it,
you must place it in the default Windows directory.
The default options for Blanker are:
Delay = 3 (minutes)
Blank DOS = No
Instant Blank = Yes
Most people will want to load Blanker whenever Windows is active. To do
this, add "BLANKER.EXE" to either the RUN= or LOAD= lines in your WIN.INI
file. (If BLANKER.EXE is not in your search path, be sure to add the path!)
Once Blanker is installed it can be removed from memory by running it a
second time. A message will be displayed that it has been removed. If you
want to load and unload frequently for whatever reasons, you might wish
to add Blanker to one of your Program Manager groups.
Operational Notes
=================
For "instant blanking", just put your mouse in the extreme upper-left
corner of the screen and leave it be. The screen will blank within 5
seconds (unless you have the "Instant Blank" option turned off).
If you choose to blank DOS sessions (only applicable to full-screen DOS
apps running under 386-Enhanced mode), it will take approximately
15 (fifteen) times longer to blank than the normal delay. Please note
carefully --> if you leave a DOS app in full-screen mode, and have the
option set to blank DOS apps, it will try to blank even if you are still
typing! I have found that most users who utilize DOS sessions full-screen
switch back to Windows occasionally (which will reset the timer) so that
this is not a problem. Also note -- if you are running a large file transfer
from a DOS app (such as ProComm PLUS), you should probably leave this option
disabled. For the record, I leave the DOS-blanking option off and simply
return to Windows (Control-Escape) when I am done with a DOS app.
Blanker will NOT operate properly in a large-frame EMS envionment (Real-mode).
Very few people use this mode, and I chose to ignore it in order to keep
Blanker as small and efficient as possible.
