- [from SIMTEL20's PD:<MSDOS.SCREEN>UNBLINK.ARC
-
- This utility can be used to change the cursor from blinking to
- non-blinking and back again. When it is in the non-blinking
- mode the output to the screen will be a little slower, however.
-
- v1.2
- Toad Hall disassembly and tweak
- - Tweaked a bit, cleaned up code.
- - Moved a bunch of install-time data and code out of TSR code
- to reduce TSR code size.
- - Can't test with color (no color card). Seems to work just fine on
- my PC-DOS 3.1 system w/Hercules-compatible monographics card, both in
- monochrome and CGA-emulation mode.
-
- This utility steals Interrupt vectors 9, 10H, 20H, and 28H.
- Installed size/memory requirements:
- v1.1: 1984 bytes (232 16-byte paragraphs)
- v1.2: 960 bytes (168 16-byte paragraphs)
-
- Incidentally, this utility uses the User Interprocess Communications
- area (bytes 0:04FEH and 0:04FFH), the first one I've seen!
- Hope no one else (important) is using these two bytes! The unique flags
- used for installation flagging are:
- 0:04FEH - 'b'
- 0:04FFH - 1
- (obviously the version number (1.1b). These installed flags are NOT
- changed in my tweaked version.
-
-
- Rights, copyright, etc. remain with original authors. (And, NO,
- I won't release the disassembled/tweaked source code.) Of course,
- you take full responsibility for using the tweaked v1.2; I disclaim
- any and all responsibility for any bad effects, losses, etc.
-
- Donno what you're gonna do about the "registration bounty" offered
- (see the help screen). The version I received had no serial number,
- so there's no one to credit!
-
- Usage:
- UNBLINK gives short help screen, doesn't install
- UNBLINK /i Copyright notice display, goes TSR.
- (Cursor might not instantly disappear, but it will!
- To toggle disappearing/normal cursor:
- Press the ALT key three times, then the character 'u'.
