- PROGRAM DESCRIPTION
- -----------------------------------------------------------------
-
- 1. Screen Dimmer.
-
- VgaDim+ blanks the screen at a preset interval after last
- keyboard or mouse use. This reduces monitor burn-out and
- prolonges monitor life.
- To restore the screen, simply touch any key or mouse button.
- This keystroke will NOT be passed to the currently active
- program.
-
- 2. Dimmer-Switch.
-
- The screen can also be blanked immediately upon pressing the
- dimmer-switch key combination (e.g: [Scrol Lock]).
- Once the dimmer-switch is used, only the same combination
- (i.e: [Scroll Lock]) will restore the screen.
-
- Since the dimmer-switch keys can be changed and set to any
- combination, you can effectively use this feature to prevent
- an unauthorized use of your computer while you are away.
-
-
- 3. Keyboard password lock
-
- VgaDim+ will optionally automatically lock the keyboard upon
- the time-out period (or pressing the dimmer switch key.)
- The keyboard is then unlocked upon entering the password.
- The password can be any 4-digit number you specify.
-
- Starting VgaDim+ from AUTOEXEC.BAT with the password lock
- feature would prevent an unauthorized use even if the computer
- is rebooted. The only way to circumvent this would be to boot
- from a diskette and remove VgaDim from AUTOEXEC.BAT.
-
- 4. Speaker silencing.
-
- Some programs insist on greeting you with a long and loud beep
- with every unimportant message or for every minor mistake you
- make, and would not let you turn the sound off.
- The VgaDim+ speaker silencing feature will turn those beeps
- into short clicks.
-
- Since all the VgaDim+ features can be enabled or disabled
- separately, you can use VgaDim+ for the speaker silencing,
- even if you do not have a VGA card/monitor.
-
- 5. Audible alarm.
-
- As a reminder that the screen is blanked, VgaDim+ generates
- audible tone scale every time-out period. This scale can be
- set to generate anywhere from 1 to over 60 tones. You can
- also specify the starting note's pitch.
- To turn the Audible Alarm OFF, turn the Speaker Silencer ON.
-
- -----------------------------------------------------------------
- PROGRAM REQUIREMENTS
- -----------------------------------------------------------------
-
- 1. Memory requirements.
-
- 1 KB.
-
- VgaDim+ is a terminate-and-stay-resident (TSR) program which
- remains in memory, until it is explicitly removed (or the
- computer is re-booted or turned off.)
- VgaDim+ occupies only 1024 bytes of memory (1 KB) and can be
- removed from memory anytime.
-
- 2. Video cards/modes supported.
-
- VGA (Video Graphics Array), all video modes.
-
- The blanking works in all VGA text and graphics video modes.
- The speaker silencing and keyboard lock features do not require
- a VGA card to operate.
-
- 3. Loading/removal.
-
- Preferred sequence = LAST IN / FIRST OUT.
-
- VgaDim+ will coexist with any properly written TSR program and
- can be started/loaded in any order.
- VgaDim+ can be removed from the memory anytime, provided that
- no other TSR program has priority over the Keyboard and Timer
- interrupts at the time of unloading. This can happen if you load
- another TSR program using these interrupts after VgaDim+.
-
- The easiest way to satisfy this requirement is to unload all TSR
- programs in the reversed load sequence (i.e. Last In / First Out).
- However, if this turns out to be a cumbersome or impossible task,
- you can simply disable VgaDim+ and leave it alone since it
- occupies only 1K of memory.
-
- 4. NOTE FOR MS-WINDOWS USERS:
-
- VgaDim+ does not support MS-Windows and should be removed from
- memory or disabled prior to starting any Windows application.
- To accomplish this, edit the batch file used to start Windows
- or a run-time Windows application:
- 1) insert as the first line:
- 'VGADIM /U'
- 2) insert as the last line:
- 'VGADIM'
- This will remove VgaDim+ from memory and reload it upon the
- completion of a Windows application.
-
- -----------------------------------------------------------------
- OPERATION
- -----------------------------------------------------------------
-
- 1. Starting VgaDim+:
-
- To start VgaDim+, simply enter 'VGADIM' on the command line
- or in your AUTOEXEC.BAT. This will start VgaDim+ with default
- operating parameters:
- - Screen dimmer is ENABLED,
- - Time-out interval is set to 240 seconds (4 minutes),
- - Dimmer-Switch lock is ENABLED,
- - Dimmer-Switch key is set to [Scroll Lock],
- - Keyboard Password lock is DISABLED,
- - Mouse monitoring is ENABLED,
- - Speaker silencer is DISABLED,
- - Audible reminder tone is set to 1.
-
- You can change all these parameters while VgaDim+ is active.
- To see current operating parameters and their format, enter
- 'VGADIM' while VgaDim+ is active.
- For a detailed description, please refer to "VgaDim+ User's
- Guide and Reference", available to registered users.
-
- 2. Stopping and unloading VgaDim+:
-
- To stop and remove VgaDim+ from memory, enter 'VGADIM /U'.
