The `moused' daemon is made to support various serial mouse
protocols to recognized extra buttons and wheel/roller. It now has
PnP COM device support code, thus, some recent mouse products are
automatically detected and an appropriate protocol is selected.
The `-i' option will print the result of auto-detection.
- Added support for the following SERIAL mice:
ALPS GlidePoint, MS IntelliMouse, Kensington Thinking Mouse
(Genius NetMouse, NetMouse Pro, ASCII MieMouse, Logitech MouseMan+,
FirstMouse+ are compatible with MS IntelliMouse, when connected
to a serial port, thus requires no explicit support)
- Added PnP serial mouse identification capability as defined
by Microsoft and Hayes in "Plug and Play External COM Device
Specification, rev 1.00". This support will enable us to identify
the correct protocol to use, or choose a compatible protocol for the
given mouse.
- Utilize new ioctls defined in `mouse.h' to get hardware and protocol
information on PS/2 and bus mouse devices. Try to guess the correct
protocol and port combination based on the obtained info.
- Use MOUSE_SETLEVEL ioctl.
- Use constants defined in `mouse.h' rather than using own definitions.
- A New command line option. The -i option prints the information
collected though the PnP code and psm/mse ioctls mentioned above,
and just quits. This is to test `moused's ability, or inability, to
detect the correct protocol for the given mouse automatically.
- A new command line option. The -m option maps a physical button
to a logical button.
- A new command line option. The -z option maps the Z axis movement to
another axis or a pair of buttons.
- Add other options: -3, -C -F -P.
- Added a handler for SIGHUP. This has been suggested by somebody in the
past (I don't remember who). He wanted this because he wants to attach
or detach a mouse while his laptop is suspended. Now `moused' will
reopens and reinitialize the specified port whenever a SIGHUP is
received. I don't know how useful this can be...
- The `psm' driver is made to recognize various models of PS/2 mice
and enable their extra features so that their additional buttons and
wheel/roller are recognized. The name of the detected model will be
printed at boot time.
- A set of new ioctl functions are added to the `psm', `mse' and
`sysmouse' drivers so that the userland program (such as the X server)
can query device information and change driver settings.
- The wheel/roller movement is handled as the `Z' axis movement by the
mouse drivers and the moused daemon. The Z axis movement may be mapped
to another axis movement or buttons.
- The mouse drivers support a new, standard mouse data format,
MOUSE_PROTO_SYSMOUSE format which can encode x, y, and x axis movement
and up to 10 buttons.
/sys/i386/include/mouse.h
- Added some fields to `mousestatus_t' to store Z axis movement
and flag bits.
- Added the field `model' to `mousehw_t' to store mouse model code.
Defined model codes.
- Extended `mousemode_t'.
- Added new protocols and some constants for them.
- Added new ioctl functions and structures.
- Removed obsolete ioctl definitions.
/sys/i386/include/console.h
- Added `dz' field to the structure `mouse_data' to pass Z axis movement
to `syscons/sysmouse'.
- Removed LEFT_BUTTON, MIDDLE_BUTTON and RIGHT_BUTTON. Use button bits
defined in `mouse.h' instead.
/sys/i386/isa/psm.c
- Added a set of functions to detect various mice which have additional
features (wheel and buttons) unavailable in the standard PS/2 mouse.
- Refined existing ioctl functions and added new ones. Most important
of all is MOUSE_SETLEVEL which manipulates the output level of the driver.
While the output level remains zero, the output from the `psm' driver is
in the standard PS/2 mouse format (three bytes long). When the level
is set to one, the `psm' driver will send data in the extended format.
At the level two the driver uses the format which is native to the
connected mouse is used. (Meaning that the output from the device is
passed to the caller as is, unmodified.) The `psm' driver will pass
such extended data format as is to the caller if the output level is
two, but emulates the standard format if the output level is zero.
- Added kernel configuration flags to set initial resolution
(PSM_CONFIG_RESOLUTION) and acceleration (PSM_CONFIG_ACCEL).
- Removed the compile options PSM_ACCEL, PSM_CHECKSYNC and PSM_EMULATION.
Acceleration ratio is now specified by the kernel configuration flags
stated above. Sync check logic is refined and now standard.
The sync check can be turned off by the new kernel configuration flags
PSM_CONFIG_NOCHECKSYNC (0x100). PSM_EMULATION has been of little use.
- Summer clean up :-) Removed unused code and obsolete comments.
/sys/i386/isa/mse.c
- Created mseioctl() to deal with ioctl functions MOUSE_XXXX.
Most importantly, the MOUSE_SETLEVEL ioctl will change the
output format from the 5 byte format to the new, extended format
so that the caller can take advantage of Z axis movement and additional
buttons.
- Use constants defined in `mouse.h' rather than magic numbers.
/sys/i386/isa/syscons.c
- Changed scioctl() to reflect the new `console.h' and some of the new
ioctls defined in `mouse.h'. Most importantly, the MOUSE_SETLEVEL
ioctl will change the `sysmouse' output format from the MouseSystems
5 byte format to the new, extended format so that the caller can
take advantage of Z axis movement and additional buttons.
- Added support for double/triple click actions of the left button and
single click action of the right button in the virtual console. The
left button double click will select a word under the mouse pointer.
The triple click will select a line and the single click of the right
button will extend the selected region to the current position of
the mouse pointer. This will make the cut/paste support more compatible
with xterm.
