SCROLLit Advanced Scrollback Buffer May 30, 1993
─────────────────────────────────────────────────────────────────────────
New in SCROLLit 1.7
─────────────────────────────────────────────────────────────────────────
■ Users can now select an alternate hotkey instead of the default
Scroll Lock hotkey. The /H command line switch is used to specify a
different hotkey at installation or to change the hotkey after
SCROLLit has already been installed. For example, to install
SCROLLit with a 100k buffer and set 'Alt S' as the hotkey, type:
SCROLLIT 100 /H=81F
Please refer to the documentation for more information.
■ SCROLLit's scrollback buffer can be stored in upper memory (instead
of EMS, XMS or lower conventional memory) by using 'high loading'
software such as DOS 5's LOADHIGH command or QEMM's LOADHI program.
In some situations, the attempt to load SCROLLit's buffer into upper
memory was unsuccessful, causing the buffer to reside in lower
conventional memory. Fixed.
■ A new feature has been added for Desqview users. Some Desqview users
have reported that installing SCROLLit within a Desqview window
slows down the performance of programs operating in other Desqview
windows, despite the fact that SCROLLit releases it's timeslice
during idle keyboard polling. It turns out that any program or TSR
that hooks the timer interrupt will cause this speed degradation in
remaining Desqview windows. Quarterdeck's API programming staff have
confirmed that Desqview will wait one extra tick before giving up
the timeslice to ensure that the timer itself is serviced. The /NT
(for NoTimer) command line switch has been added to SCROLLit, to
allow installation without hooking the timer interrupt (the BIOS
keyboard interrupt is hooked instead). For example, Desqview users
who wish to optimize the performance of their system would install
SCROLLit by typing:
SCROLLIT 100 /NT
Please refer to the documentation for more information.

SCROLLit 1.6
─────────────────────────────────────────────────────────────────────────
■ Please note our new mailing address. Don't worry if you have mailed
something to our old address: we will continue to check for mail at
the old address for at least a year, or as long as mail continues to
arrive there.
■ SCROLLit can now be registered online using Compuserve's shareware
registration service ('GO SWREG'). When you register with the
service, the US$17 registration fee (plus a $3 surcharge to cover
Compuserve's service charge) is added to your monthly Compuserve
bill. Your SCROLLit registration key will be sent to you by
Compuserve mail (unless you request postal mail).
■ By default, SCROLLit uses a color scheme of blue and white against a
cyan background. While this combination looks fine on a color
monitor, some users of LCD notebooks report that these color
attributes lack definition when translated into the shades of grey
that these machines use to represent different colors. Two new
command line parameters have been added to allow the user to specify
the color attributes used in color text mode 3 (/AC=) and in
monochrome text mode 7 (/AM=). These commands can be used to set the
color attributes during installation or after SCROLLit has already
been installed. For example, to install SCROLLit with a 100k buffer
and customized color attributes for use during color mode 3, type:
SCROLLit 100 /AC=20,27,2F,07
Please refer to the documentation for more information.
■ The operation of SCROLLit inside a Desqview window has been fine-
tuned. Desqview users should notice smoother scrolling when browsing
through SCROLLit's buffer.
■ The Ctrl-Home bookmark is designed to return you to the same
position within the scrollback buffer as when you last exited
SCROLLit. In some situations, SCROLLit was not saving the correct
location within the scrollback buffer. In these cases, pressing
Ctrl-Home would either return you to an incorrect location within
the buffer, or, with some computers, cause a lockup requiring a
reboot. Fixed.
■ In certain situations (relatively rare), SCROLLit would fail during
installation, issuing an 'unexpected error 31' message and causing a
lockup requiring a reboot. Fixed.
─────────────────────────────────────────────────────────────────────────
SCROLLit 1.5
─────────────────────────────────────────────────────────────────────────
■ Pressing Ctrl-Home allows you to return to the position in the
scrollback buffer when you last exited SCROLLit. This feature is
often referred to as a 'bookmark'. Older versions of SCROLLit were
only updating the buffer position when SCROLLit was exited with the
Esc key. If you exited with the Scroll Lock key, the bookmark was
not being updated. Fixed.
■ Two new command line switches, /- and /+, have been added to allow
SCROLLit's capturing of scrolling lines to be temporarily disabled
and then re-enabled.
■ A new command line switch, /R, has been added to provide more
information on how to register SCROLLit.
■ The /? command line switch will display a list of all command line
switches with a brief description of what they do.

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. Note that some EGA/VGA cards
can provide 43/50 line mode support via the standard 80 column text
modes (modes 2, 3 and 7) and/or via a nonstandard video mode (such
as 50h). SCROLLit only supports the standard video modes, so you
should use these standard modes for 43/50 line support (using video
BIOS function 11h, subfunction 12h). If you find that you can only
enter 43/50 line mode with nonstandard modes, then try reseting the
video mode to the standard by changing the mode setting stored at
memory position 40h:49h.
■ 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.
