CuteMouse driver v1.8. Copyright (c) 1997-2000 Nagy Daniel
Release date: 2000-09-16

please read the COPYING file.
Description:
------------
CuteMouse is a mouse driver which supports many mouse protocols, serial
and PS/2. It can search for serial mice at all COM ports or only at a
specified port.
An important CuteMouse feature is its small memory footprint: the TSR part
occupies less than 3.5K. CuteMouse also can install itself in upper memory
when it is available without requiring external utilities such as DOS 'lh'
command.
CuteMouse supports cursor drawing in all standard graphics and text modes
with any screen size. These are automatically detected whenever reset
functions are called or the video mode is changed.

Details:
--------
CTMOUSE supports standard PS/2 and Mouse Systems, Microsoft (including
Intellimouse/Wheel Mouse) and Logitech serial protocols. When searching
for a connected mouse the PS/2 port is checked first then all COM ports
are scanned. Option /S, whose syntax is described in the help screen,
disables PS/2 support and can specify the COM port and the IRQ line to be
checked for a mouse connection; option /P disables serial protocols. When
a COM port must be forced but PS/2 support is also required, both options
must be present in the command line.
By default, a PS/2 mouse is searched for before a serial mouse, but option
/V reverses this. Option /V can be useful, for example, on notebooks with
a built-in PS/2 pointing device to enable use of a serial mouse, when
attached, by causing CTMOUSE to look for a serial mouse before checking
the PS/2 device. Using option /Y (see below) also may be required along
with /V. Note: option /V enables both serial and PS/2 protocols, so using
options /P and /S without arguments along with /V in the command line is
meaningless.
For serial mice, CTMOUSE searches all COM ports (or at the port specified
by option /S) for an attached Microsoft or Logitech mouse. If no such
mouse is found then CTMOUSE installs at the first existing (or specified)
COM port for a Mouse Systems mouse, whether a mouse is there or not (this
is because Mouse Systems protocol defines no detection sequence). Option
/Y in the command line disables Mouse Systems protocol support and
prevents driver installation if no Microsoft or Logitech mouse is found.
Note: option /Y forces serial mouse search but, unlike option /S, doesn't
disable PS/2 support.
Both PS/2 and plain Microsoft protocols assume two button mice but option
/3 in the command line can be used to enable the middle button if one is
present.
WARNING: when the middle button of a plain Microsoft mouse is enabled,
pressing left or right button along with the middle button can cause
"middle button state triggering" - i.e. when the middle button is pressed
the driver thinks it is released and vice-versa. This is a peculiarity of
the Microsoft protocol and can't be changed. If button triggering occurs
simply press the left or right button along with the middle button once
again to clear the problem.
CTMOUSE supports 9 fixed resolution levels plus auto resolution, which
define the relationship between cursor and mouse movement - the higher the
resolution level, the further the cursor moves for a given mouse movement.
Resolution level 1 or small mouse movements at any resolution provides a
direct relationship between cursor and mouse movement, which enables
precise screen positioning even at the highest resolution levels. Larger
mouse movements and higher resolution levels are multiplied together to
determine the cursor movement, enabling rapid cursor movements across the
screen for relatively small mouse movements.
Auto resolution means dynamic resolution change, where the faster the
mouse moves, the greater the resolution by which the mouse movements are
multiplied, giving the cursor a nonlinear acceleration. Option /R, whose
syntax is described in the help screen, allows the preferred resolution
level to be specified for each direction.
If installing from low memory, CTMOUSE attempts to move itself into upper
memory (UMB) if there is a suitable free UMB block and option /W is not
used. With option /W any external utility can be used to install CTMOUSE
at a specific location. Subsequent CTMOUSE runs simply reset the resident
part to the new command line options, unless the mouse is not found or
option /B is used.
When installing, CTMOUSE also ignores and hides any present mouse services
unless option /B is used. Option /U in command line can be used to unload
the resident part of CTMOUSE unless driver interrupts have been
intercepted by another program. After successful unloading, CTMOUSE
restores mouse services that were present at installation time.
Option /B in the command line cancels CTMOUSE execution if any (including
CTMOUSE itself) mouse services are already present. With option /B CTMOUSE
will not install itself above loaded mouse drivers and will not reset the
resident part to new command line options.
For each event CTMOUSE returns an appropriate exit code which can be used
in "if errorlevel" statements in batch files:
0 - PS/2, Microsoft or Logitech mouse found and CTMOUSE installed;
unload successful;
/? option used
1 - CTMOUSE installed for Mouse Systems protocol;
unload failed - CTMOUSE not installed
2 - resident part switched to PS/2, Microsoft or Logitech protocol;
unload failed - driver interrupts intercepted
3 - resident part switched to Mouse Systems protocol
4 - mouse services already present (returned for option /B only)
5 - mouse not found;
invalid option used
Along with option /B, this enables creation of complex batch files. For
example, the following batch can be used to run a program that requires
mouse services to be present:
if "%1"=="@" goto skipmouse
ctmouse/b/y>nul
if errorlevel 5 echo Mouse not found!
if errorlevel 5 goto end
if errorlevel 2 goto run
call %0 @ %1 %2 %3 %4 %5 %6 %7 %8 %9
ctmouse/u>nul
goto end
:skipmouse
shift
:run
<program> %1 %2 %3 %4 %5 %6 %7 %8 %9
:end
Option /B can also be used to manually specify a mouse search sequence. In
the following example, CTMOUSE is installed by the first command that
finds a mouse and the following commands will have no affect on the
resident part:
ctmouse/b/s4/y>nul
ctmouse/b/p/y>nul
ctmouse/b/s2/y>nul
A help screen with all option descriptions can be obtained with the /?
command line option.
The CuteMouse package also includes a protocol analyzer. This program
shows how mice work and what they send to the computer for each action.
PROTOCOL can even decipher information sent by PNP mice. All output goes
through DOS functions and can be redirected to a file for subsequent
analysis or sending to someone else.
Compiling:
----------
To assemble the English version of the driver use TASM (or any compatible
assembler) and any linker that can produce a COM file from OBJ files:
copy ctm-en.msg ctmouse.msg
tasm /m ctmouse.asm
tlink /t /x ctmouse.obj,ctmouse.exe
ctm2exe ctmouse.exe
To assemble the serial protocol analyzer:
tasm /m protocol.asm
tlink /t /x protocol.obj
To compile or delete temporary files, the MAKE utility also can be used
(see makefile).
