2.1beta4 by Eric Auer 7/2008
- intermediate release, prints PS/2 debugging output during
mouse init and when mouse is activated / stopped later
- Dell Inspiron 1501 touchpad has no int 15.c204 ident in
BIOS, so we use PS/2 even without ident (as ctmouse 1.9)
- option /O changed from disable to enable wheel detection
(only few DOS apps use wheels, and wheel is less compatible)
- option /M (disable old MouseSystems / Genius) is now the
default, so there is a new option /Y to enable MouseSystems.
- lots of changes in the source code to let it compile with
the MASM-ized JWASM of Japheth.de (based on OpenWatcom WASM)
instead of the commercial TASM. Disabled many macros.
- this version comes with TASM and JWASMD binaries so you can
compare them: ctmouse binaries are byte identical with the
exception of protocol.com where I had to fix a bug :-p.
2.1beta3 by Eric Auer 6/2007
- new mousetst binary with sources written in NASM Assembly
language. Supports wheel testing, so removed wheeltst.
The old BC3.1 mousetst was very un-portable to another C.
Updated makefile mousetst section. New mousetst is 1kB :-).
- directory structure changed to something more elaborate, with
bin/, doc/ctmouse/ and source/ctmouse/ with subdirectories.
This also allows easy installation in FreeDOS, just unzip.
- dropped packed / unpacked distinction, but feel free to aPack
binaries yourself (upx somehow refuses to compress ctmouse?).
2.1beta2 by Eric Auer
- new /O option to suppress wheel detection: Might improve PnP for
serial mice, but main use is for PS/2. USB BIOS support usually
does not support the "enable wheel protocol" handshake, and if
you hotplug a mouse (NOT recommended for PS/2), it will boot in
non-wheel mode. The TSR cannot detect and fix that mode change.
- made E_needvga message translateable. The message tells that this
CuteMouse version does not support non-VGA plain EGA hardware.
- improved the English help message :-)
- TODO: also update the other message files for other languages!
- TODO: Find sources of com2exe and include them...
- TODO: compile and include translated binaries
- other TODO / BUGS as in 2.1beta
2.1beta by Eric Auer <eric*coli.uni-sb.de>
- removed RIL interface: non-RIL apps caused graphics corruption
- reading VGA registers: no RIL needed but VGA hardware needed
- backup/restore VGA registers in copysprite
- replaced hardware PS/2 by BIOS PS/2 handling again for better
compatibility, based on public domain source fragment by Konstantin Koll
- removed PS/2 IRQ handler by BIOS callback handler. Wheel data
protocol processing again based on code from Konstantion.
- removed "XMS UMB" allocate / free: only DOS UMB worked anyway
- do not disablePS2 right before enablePS2 (IRQ/settings)
- store only CRTC port (3d4/3b4), not full videoregs structure
- explicitly set "blit mode" for EGA/VGA (not for CGA/MCGA)
- introduce a handfull nop to mark interesting places in the code
- enabledriver_20 explicitly sets int10 handler to CS:...
- show error message if pre-VGA, old version only tuned videoregs if EGA
- TODO?: command line options for resolution / rate, VESA cursor,
- TODO?: disabledrv_1F/enable/reset could / should set resolution / rate
- TODO??: support USB wheel mice - BIOS PS2 interface wheel handshake
fails if mouse is not at PS2. Mouse on USB works, wheel does not.
8042 handshake had the same problem, 8042 is virtual / BIOS if USB.
- BUG?: mode 10h cursor has rectangular hole around it, ONLY in dosemu
2.0 by Nagy Daniel <[email protected]>
- Hardware PS/2 handling reintroduced (tests and comments by Hubert Sack
<[email protected]> and Bernd Krueger-Knauber <[email protected]>).
- Added new wheel API.
- Added wheel tester utility.
by Jason Burgon <[email protected]>
- Implemented INT 33/0028; the DX argument is ignored.
- Reimplemented functions INT 33/001A and 001B to mimic MS Mouse behavior.
- Changed semantics of the /R command line option: its arguments multiplied
by 10 and passed to 001A function.
by Arkady V.Belousov <[email protected]>
- Cleaned and optimized source code and fixed many bugs.
1.9.1 by Arkady V.Belousov <[email protected]>
by Maurizio Spagni <[email protected]>
- Fixed bug in INT 33/0017; under Turbo Pascal IDE this bug caused crash
in some cases.
by Nagy Daniel <[email protected]>
- INT 33/0005 and 0006 functions now return zero values in case of wrong
button number in BX; this makes game Patrician happy.
1.9 by Arkady V.Belousov <[email protected]> (documentation proofreading by
Frank Markopoulos <[email protected]>, Wœrm <[email protected]>,
Wolf Bergenheim <[email protected]>, Jim Lemon and Graeme England)
- Heavy source cleaning and optimization.
- INT 33/001A and 001B functions are temporarily disabled because their
descriptions in RBIL 61 don't correspond with MS Mouse behavior and this
causes cursor slowdown in some applications (for example, SimCity 2000).
- For the /Sn/P option combination INT 33/0024 now returns the proper IRQ#.
- INT 33/001F function now retains DTR and RTS UART lines active.
- Removed flush of mouse data stream when detecting mouse type
(this also prevents infinite loops in some cases under Windows).
- Small mouse movements are now also doubled in auto resolution mode.
- Cursor drawing routines now recall themselves if interrupt handlers try
to call them while drawing routines work; this should avoid differences
between seen and real cursor status in some rare cases.
- LCR and MCR now preserved in UARTs for which no mouse is detected.
- Added additional check for PS/2 device presence (this prevents big
delay at startup in some cases under Windows).
- Added support for 286 and 386 CPUs.
- Added external assembler library.
- Added Dutch, French, Latvian, Polish, Slovak and Spanish message files.
- Added /N command line option to force load of CuteMouse as a new TSR.
- COMTEST utility improved (and may be used to integrate IRQ auto
detection into CuteMouse).
by Donald G.Davis <[email protected])
- Added closing of all local file handles before exit (this prevents leakage
from system handles pool when CTMOUSE is called with redirected output and
stays TSR).
by Jason Burgon <[email protected]>
- INT 33/0024 and 006D now report driver version 7.05 instead of 6.26.
- Implemented function INT 33/0031.
- CTMOUSE now handles INT 10/4F02 and some INT 10/11 video functions and
correctly recalculates screen size when, for example, the screen is
switched to 43/50 lines text mode.
1.8 by Arkady V.Belousov <[email protected]> (some ideas by Alain Mouette
<[email protected]>, documentation proofreading by Mike Millen
<[email protected]> and Frank Markopoulos <[email protected]>)
- Bugfixes, heavy optimizations, some features.
- PS/2 pointing devices were not found on some machines.
- Serial mouse reset reinforced (previously mouse froze in some cases).
- Serial and PS/2 modules combined into one executable.
- For Mouse Systems protocol, CTMOUSE now installs at first existing
COM port, not at COM1 which may be absent.
- Added support for serial Microsoft wheel protocol, wheel interpreted
as third button.
- Auto resolution behavior corrected and is now default resolution.
- INT 33/001F now doesn't restore interrupts (and CTMOUSE doesn't unload
resident part) if INT 33 or INT 10 are intercepted by another program.
- Cursor drawing much enhanced and bugfixed: finished INT 33/0010
support and video page change detection for graphics drawing; single
video registers handled in RIL more accurately; cursor is drawn only
when cursor shape is inside screen ranges.
- Some ill-behaved applications (like Norton Commander or Klondike
by Eduardo Martins) call INT 33/0001, 0009 and 000A in loops; to
prevent cursor flickering, the cursor is now redrawn only if its
position or pattern is changed.
- Added workarounds for Pentium and PS/2 BIOS, Logitech MouseWare
Windows driver, Turbo Pascal IDE and Nicemouse utility peculiarities.
- Messages for English extracted into separate message file.
- Added Brazilian, Portugese, German, Italian and Hungarian message files.
- Ordered errorlevels returned for each event.
- Added /B command line option to cancel run if mouse services are
already present.
1.73 by Arkady V.Belousov <[email protected]> (many ideas by Alain Mouette

accepts PnP mice.
- Changed command line interface.
- Added mouse autosearch through all COM ports.
- Added support for Microsoft and PS/2 mice with 3 buttons.
