- SCROLLit Advanced Scrollback Buffer December 14, 1992
-
-
- ─────────────────────────────────────────────────────────────────────────
- New in SCROLLit 1.4
- ─────────────────────────────────────────────────────────────────────────
-
- ■ SCROLLit now supports 43/50 line mode of the EGA/VGA. Actually,
- SCROLLit will support any number of lines per screen so long as the
- BIOS is aware of the new line setting.
-
- ■ SCROLLit was not supporting the color video mode 3 on certain
- monochrome monitors. SCROLLit will now allow any 80 column text mode
- (modes 2,3 or 7) on any monitor type. After installation, the video
- mode can be switched between these modes and SCROLLit will still
- capture scrolling and popup on request.
-
- ■ The default keyboard repeat rate on many computers is a relatively
- slow 10.9 repeats per second. The keyboard repeat rate determines
- how fast SCROLLit will scroll the screen when you press and hold the
- up arrow or down arrow key. SCROLLit was setting a fast keyboard
- repeat rate on installation, but this new repeat rate would effect
- all subsequent keypresses (not just SCROLLit). Some users have
- pointed out that it is better for each user to set the repeat rate
- he or she is most comfortable with. The keyboard repeat rate can be
- set with DOS 5.0's MODE command or any number of public domain
- utilities. SCROLLit 1.4 no longer changes the keyboard repeat rate.
-
- ■ SCROLLit captures 'clear-screen' requests in addition to both DOS
- and BIOS screen scrolling. When you use the CLS command, for
- example, SCROLLit will capture the information on the screen before
- it is cleared. In addition, many programs clear the screen at
- startup, which would leave gaps in your scrollback buffer if
- SCROLLit did not intercept the clear-screen request. Another example
- of the need to capture clear-screens is during Compuserve sessions
- when the Compuserve terminal type is set to be page oriented.
- Instead of scrolling old output, Compuserve issues a clear-screen
- request after every page. SCROLLit will now capture these pages.
-
- ■ If 'search again, same text' was requested by pressing A before a
- target string had ever been specified with either F (forward) or B
- (backward), SCROLLit would hang while trying to search for an
- undefined target string. Fixed.
-
- ■ It is now possible to popup other TSR programs over SCROLLit. This
- is accomplished by issuing a 28h interrupt while SCROLLit is waiting
- for input. If you use a popup calculator or screen grabber, for
- example, they should now work while you are in SCROLLit.
-
- ■ The Procomm commands in the Appendix for setting BIOS screen
- scrolling were for the old shareware version of Procomm 2.4.3.,
- not for Procomm Plus which needs no reconfiguring. The Qmodem
- command given was for BIOS writing, not BIOS scrolling. Fixed.

- SCROLLit 1.3
- ─────────────────────────────────────────────────────────────────────────
-
- ■ SCROLLit 1.2 was not properly restoring the state of the A20 line
- when the buffer was stored in XMS. This would cause the system to
- hang in some cases, particularly if SCROLLit was installed in a
- Desqview window and DV was using the high memory area (HMA). Fixed.
-
-
- ─────────────────────────────────────────────────────────────────────────
- SCROLLit 1.2
- ─────────────────────────────────────────────────────────────────────────
-
- ■ During installation, SCROLLit performs a CRC test of the program to
- ensure that the program has not been tampered with or infected with
- a virus. This CRC test would fail in Version 1.1 if SCROLLit was
- loaded in a Desqview window. Fixed.
-
- ■ Under certain circumstances, some versions of The Last Byte Memory
- Manager appear to have difficulty loading a TSR into high memory if
- the particular TSR has command line parameters beginning with a
- slash (/). SCROLLit 1.2 will now accept either slashes or dashes.
-
-
- ─────────────────────────────────────────────────────────────────────────
- SCROLLit 1.1
- ─────────────────────────────────────────────────────────────────────────
-
- ■ Broader support for ANSI drivers. Version 1.0 was not capturing some
- of the screen scrolling from certain ANSI drivers including older
- (1987 and earlier) versions of Microsoft's ANSI.SYS. SCROLLit
- Version 1.1 has been tested with several versions of ANSI.SYS,
- ANSI.COM, NANSI.SYS, ZANSI.SYS, VANSI.SYS and DVANSI.COM. In the
- case of the TSR drivers, (ANSI.COM and DVANSI.COM), SCROLLit should
- be loaded AFTER the driver.
-
- ■ SCROLLit is now Desqview aware. If SCROLLit is loaded inside a
- Desqview window, it will capture the scrolling of the Desqview screen
- buffer, rather than the hardware screen buffer that is used outside
- of Desqview. SCROLLit will give up it's time slice during periods of
- inactivity to optimize the performance of your other Desqview
- windows. All screen writing inside a Desqview window is direct
- writing to the Desqview screen buffer, to ensure that SCROLLit output
- stays within the Desqview window.
-
- ■ Scrolling algorithm finetuned - smaller code and faster performance.
