- Description
- ───────────
-
-
- SCRNSAVE.COM is a TSR screen-blanking utility for the EGA (and VGA).
- As of this writing, it has been in use on several computers for two
- years; no reports of bugs or incompatibilities with other TSRs have
- emerged. In response to an unexpected number of recent requests,
- and despite the late date ("Just what the world needs: another EGA
- screen blanker."), I am releasing the program.
-
-
- The present version (2.1) of SCRNSAVE has a few features that may
- give it an edge over other similar utilities:
-
- * the timeout interval can be set from the command line;
-
- * automatic screen blanking can be disabled and
- reenabled from the command line;
-
- * the screen can be immediately blanked with a hotkey;
-
- * SCRNSAVE checks if an EGA (or VGA) is present before
- installing itself, and in the absence of such an
- adapter will not remain resident;
-
- * when resident, SCRNSAVE consumes only 550 bytes
- (not counting the size of the environment in force
- at the time of installation, which neither DOS nor
- SCRNSAVE frees);
-
- * even within many programs that sieze the keyboard (for
- instance, Windows), the screen can be automatically
- un-blanked by hitting any shift key;
-
- * of course, it checks to see if it is already resident
- before installing itself, and will not install itself
- twice.

- Hotkey
- ──────
-
- The screen may be blanked from the keyboard with the hotkey
- Alt-Shift-Ctrl-B. On "enhanced" (sic !) keyboards, either
- the lefthand or righthand shift keys (i.e., all three of them)
- may be used.
-
-
- Syntax
- ──────
-
- ┌─ ─┐
- SCRNSAVE │ -n │
- │ -ON │
- │ -OFF │
- └─ ─┘
- where
-
- if -n is given, (1 ≤ n ≤ 60), then the screen will blank
- after n minutes of no keyboard activity;
-
- if -ON is given, then screen blanking is (re-)enabled,
- using the last timeout value (the default
- is 5);
-
- if -OFF is given, then screen blanking is disabled.
-
- Giving no parameter is is equivalent to specifying "-ON"; SCRNSAVE
- will ensure that the screen is not blanked, and will report the
- current timeout interval.
-
- If any other parameter is given, SCRNSAVE reports its state
- (installed or not), and writes its syntax (including the hotkey !).
- Thus,
-
- SCRNSAVE ?
-
- provides a crib-sheet.
