- EGABLANK
- PC Magazine, 9/30/86
-
- "EGABLANK" is a program described in the PC TUTOR section of the 9/30/86
- issue of PC Magazine to be included in your autoexec.bat file (or to be
- otherwise invoked on demand, if you'd prefer) to blank an EGA or EGA
- compatible screen after n minutes. (Programs like SCRN.COM will NOT blank
- an EGA screen).
-
- The program was written to blank the screen after 7-1/2 minutes of keyboard
- inactivity. However, it can be revised to increase or decrease the wait
- before blanking by revising the line 'MOV WO [010A],2000' to something
- else. "A value of 1 will blank the screen every 55 milliseconds. Going up
- to FFFF gives you about an hour before the lights go out."
-
- "While it is really intended only for the monochrome display (these are the
- ones susceptible to phosphor burn), it will also work with a color display
- attached to an EGA."
-
- "EGABLANK will not work well with programs that entirely steal the keyboard
- interrupt, since it then has no way of knowing when keys have been struck.
- If you have any of these programs, you probably know about this, since
- other resident programs won't work with them either."
-
- I have an Amdek 722 EGA color monitor. SCRN.COM will NOT blank my screen
- as it would with my standard IBM color monior.
-
- I keyed in and debugged the source code included in this ARC file and
- immediately invoked the resulting EGABLANK program. IT WORKED, blanking my
- screen after the promised 7-1/2 minutes of inactivity!
