     moused -- pass mouse data to the console driver

     moused [-DPRacdfs] [-I file] [-F rate] [-r resolution] [-S baudrate]
            [-VH [-U distance]] [-a X[,Y]] [-C threshold] [-m N=M] [-w N]
            [-z target] [-t mousetype] [-l level] [-3 [-E timeout]]
            [-T distance[,time[,after]]] -p port

     moused [-Pd] -p port -i info

     The moused utility and the console driver work together to support mouse
     operation in the text console and user programs.  They virtualize the
     mouse and provide user programs with mouse data in the standard format
     (see sysmouse(4)).

     The mouse daemon listens to the specified port for mouse data, interprets
     and then passes it via ioctls to the console driver.  The mouse daemon
     reports translation movement, button press/release events and movement of
     the roller or the wheel if available.  The roller/wheel movement is
     reported as ``Z'' axis movement.

     The console driver will display the mouse pointer on the screen and pro-
     vide cut and paste functions if the mouse pointer is enabled in the vir-
     tual console via vidcontrol(1).  If sysmouse(4) is opened by the user
     program, the console driver also passes the mouse data to the device so
     that the user program will see it.

     If the mouse daemon receives the signal SIGHUP, it will reopen the mouse
     port and reinitialize itself. Useful if the mouse is attached/detached
     while the system is suspended.

     If the mouse daemon receives the signal SIGUSR1, it will stop passing
     mouse events. Sending the signal SIGUSR1 again will resume passing mouse
     events. Useful if your typing on a laptop is interrupted by accidentally
     touching the mouse pad.

     The following options are available:

     -3      Emulate the third (middle) button for 2-button mice.  It is emu-
             lated by pressing the left and right physical buttons simultane-

     -C threshold
             Set double click speed as the maximum interval in msec between
             button clicks.  Without this option, the default value of 500
             msec will be assumed.  This option will have effect only on the
             cut and paste operations in the text mode console.  The user pro-
             gram which is reading mouse data via sysmouse(4) will not be

     -D      Lower DTR on the serial port.  This option is valid only if
             mousesystems is selected as the protocol type.  The DTR line may
             need to be dropped for a 3-button mouse to operate in the
             mousesystems mode.

     -E timeout
             When the third button emulation is enabled (see above), the
             moused utility waits timeout msec at most before deciding whether
             two buttons are being pressed simultaneously.  The default time-
             out is 100 msec.

     -F rate
             Set the report rate (reports/sec) of the device if supported.

     -H      Enable ``Horizontal Virtual Scrolling''.  With this option set,
             holding the middle mouse button down will cause motion to be
             interpreted as horizontal scrolling.  Use the -U option to set
             the distance the mouse must move before the scrolling mode is
             activated.  This option may be used with or without the -V

     -I file
             Write the process id of the moused utility in the specified file.
             Without this option, the process id will be stored in

     -P      Do not start the Plug and Play COM device enumeration procedure
             when identifying the serial mouse.  If this option is given
             together with the -i option, the moused utility will not be able
             to print useful information for the serial mouse.

     -R      Lower RTS on the serial port.  This option is valid only if
             mousesystems is selected as the protocol type by the -t option
             below.  It is often used with the -D option above.  Both RTS and
             DTR lines may need to be dropped for a 3-button mouse to operate
             in the mousesystems mode.

     -S baudrate
             Select the baudrate for the serial port (1200 to 9600).  Not all
             serial mice support this option.

     -T distance[,time[,after]]
             Terminate drift.  Use this option if mouse pointer slowly wanders
             when mouse is not moved.  Movements up to distance (for example
             4) pixels (X+Y) in time msec (default 500) are ignored, except
             during after msec (default 4000) since last real mouse movement.

     -V      Enable ``Virtual Scrolling''.  With this option set, holding the
             middle mouse button down will cause motion to be interpreted as
             scrolling.  Use the -U option to set the distance the mouse must
             move before the scrolling mode is activated.

     -U distance
             When ``Virtual Scrolling'' is enabled, the -U option can be used
             to set the distance (in pixels) that the mouse must move before
             the scrolling mode is activated.  The default distance is 3 pix-

     -a X[,Y]
             Accelerate or decelerate the mouse input.  This is a linear
             acceleration only.  Values less than 1.0 slow down movement, val-
             ues greater than 1.0 speed it up.  Specifying only one value sets
             the acceleration for both axes.

     -c      Some mice report middle button down events as if the left and
             right buttons are being pressed.  This option handles this.

     -d      Enable debugging messages.

     -f      Do not become a daemon and instead run as a foreground process.
             Useful for testing and debugging.

     -i info
             Print specified information and quit.  Available pieces of infor-
             mation are:

             port      Port (device file) name, i.e. /dev/cuad0, /dev/mse0 and
             if        Interface type: serial, bus, inport or ps/2.
             type      Protocol type.  It is one of the types listed under the
                       -t option below or sysmouse if the driver supports the
                       sysmouse data format standard.
             model     Mouse model.  The moused utility may not always be able
                       to identify the model.
             all       All of the above items.  Print port, interface, type
                       and model in this order in one line.

             If the moused utility cannot determine the requested information,
             it prints ``unknown'' or ``generic''.

     -l level
             Specifies at which level moused should operate the mouse driver.
             Refer to Operation Levels in psm(4) for more information on this.

     -m N=M  Assign the physical button M to the logical button N.  You may
             specify as many instances of this option as you like.  More than
             one physical button may be assigned to a logical button at the
             same time.  In this case the logical button will be down, if
             either of the assigned physical buttons is held down.  Do not put
             space around `='.

     -p port
             Use port to communicate with the mouse.

     -r resolution
             Set the resolution of the device; in Dots Per Inch, or low,
             medium-low, medium-high or high.  This option may not be sup-
             ported by all the device.

     -s      Select a baudrate of 9600 for the serial line.  Not all serial
             mice support this option.

     -t type
             Specify the protocol type of the mouse attached to the port.  You
             may explicitly specify a type listed below, or use auto to let
             the moused utility automatically select an appropriate protocol
             for the given mouse.  If you entirely omit this option in the
             command line, -t auto is assumed.  Under normal circumstances,
             you need to use this option only if the moused utility is not
             able to detect the protocol automatically (see Configuring Mouse

             Note that if a protocol type is specified with this option, the
             -P option above is implied and Plug and Play COM device enumera-
             tion procedure will be disabled.

             Also note that if your mouse is attached to the PS/2 mouse port,
             you should always choose auto or ps/2, regardless of the brand
             and model of the mouse.  Likewise, if your mouse is attached to
             the bus mouse port, choose auto or busmouse.  Serial mouse proto-
             cols will not work with these mice.

             For the USB mouse, the protocol must be auto.  No other protocol
             will work with the USB mouse.

             Valid types for this option are listed below.

             For the serial mouse:
             microsoft        Microsoft serial mouse protocol.  Most 2-button
                              serial mice use this protocol.
             intellimouse     Microsoft IntelliMouse protocol.  Genius Net-
                              Mouse, ASCII Mie Mouse, Logitech MouseMan+ and
                              FirstMouse+ use this protocol too.  Other mice
                              with a roller/wheel may be compatible with this
             mousesystems     MouseSystems 5-byte protocol.  3-button mice may
                              use this protocol.
             mmseries         MM Series mouse protocol.
             logitech         Logitech mouse protocol.  Note that this is for
                              old Logitech models.  mouseman or intellimouse
                              should be specified for newer models.
             mouseman         Logitech MouseMan and TrackMan protocol.  Some
                              3-button mice may be compatible with this proto-
                              col.  Note that MouseMan+ and FirstMouse+ use
                              intellimouse protocol rather than this one.
             glidepoint       ALPS GlidePoint protocol.
             thinkingmouse    Kensington ThinkingMouse protocol.
             mmhitab          Hitachi tablet protocol.
             x10mouseremote   X10 MouseRemote.
             kidspad          Genius Kidspad and Easypad protocol.
             versapad         Interlink VersaPad protocol.

             GTCO Digipad protocol.

             For the bus and InPort mouse:
             busmouse         This is the only protocol type available for the
                              bus and InPort mouse and should be specified for
                              any bus mice and InPort mice, regardless of the

             For the PS/2 mouse:
             ps/2             This is the only protocol type available for the
                              PS/2 mouse and should be specified for any PS/2
                              mice, regardless of the brand.

             For the USB mouse, auto is the only protocol type available for
             the USB mouse and should be specified for any USB mice, regard-
             less of the brand.

     -w N    Make the physical button N act as the wheel mode button.  While
             this button is pressed, X and Y axis movement is reported to be
             zero and the Y axis movement is mapped to Z axis.  You may fur-
             ther map the Z axis movement to virtual buttons by the -z option

     -z target
             Map Z axis (roller/wheel) movement to another axis or to virtual
             buttons.  Valid target maybe:
             y    X or Y axis movement will be reported when the Z axis move-
                  ment is detected.
             N    Report down events for the virtual buttons N and N+1 respec-
                  tively when negative and positive Z axis movement is
                  detected.  There do not need to be physical buttons N and
                  N+1.  Note that mapping to logical buttons is carried out
                  after mapping from the Z axis movement to the virtual but-
                  tons is done.
             N1 N2
                  Report down events for the virtual buttons N1 and N2 respec-
                  tively when negative and positive Z axis movement is
             N1 N2 N3 N4
                  This is useful for the mouse with two wheels of which the
                  second wheel is used to generate horizontal scroll action,
                  and for the mouse which has a knob or a stick which can
                  detect the horizontal force applied by the user.

                  The motion of the second wheel will be mapped to the buttons
                  N3, for the negative direction, and N4, for the positive
                  direction.  If the buttons N3 and N4 actually exist in this
                  mouse, their actions will not be detected.

                  Note that horizontal movement or second roller/wheel move-
                  ment may not always be detected, because there appears to be
                  no accepted standard as to how it is encoded.

                  Note also that some mice think left is the negative horizon-
                  tal direction; others may think otherwise.  Moreover, there
                  are some mice whose two wheels are both mounted vertically,
                  and the direction of the second vertical wheel does not
                  match the first one.

   Configuring Mouse Daemon
     The first thing you need to know is the interface type of the mouse you
     are going to use.  It can be determined by looking at the connector of
     the mouse.  The serial mouse has a D-Sub female 9- or 25-pin connector.
     The bus and InPort mice have either a D-Sub male 9-pin connector or a
     round DIN 9-pin connector.  The PS/2 mouse is equipped with a small,
     round DIN 6-pin connector.  Some mice come with adapters with which the
     connector can be converted to another.  If you are to use such an
     adapter, remember the connector at the very end of the mouse/adapter pair
     is what matters.  The USB mouse has a flat rectangular connector.

     The next thing to decide is a port to use for the given interface.  For
     the bus, InPort and PS/2 mice, there is little choice: the bus and InPort
     mice always use /dev/mse0, and the PS/2 mouse is always at /dev/psm0.
     There may be more than one serial port to which the serial mouse can be
     attached.  Many people often assign the first, built-in serial port
     /dev/cuad0 to the mouse.  You can attach multiple USB mice to your system
     or to your USB hub.  They are accessible as /dev/ums0, /dev/ums1, and so

     You may want to create a symbolic link /dev/mouse pointing to the real
     port to which the mouse is connected, so that you can easily distinguish
     which is your ``mouse'' port later.

     The next step is to guess the appropriate protocol type for the mouse.
     The moused utility may be able to automatically determine the protocol
     type.  Run the moused utility with the -i option and see what it says.
     If the command can identify the protocol type, no further investigation
     is necessary on your part.  You may start the daemon without explicitly
     specifying a protocol type (see EXAMPLES).

     The command may print sysmouse if the mouse driver supports this protocol

     Note that the type and model printed by the -i option do not necessarily
     match the product name of the pointing device in question, but they may
     give the name of the device with which it is compatible.

     If the -i option yields nothing, you need to specify a protocol type to
     the moused utility by the -t option.  You have to make a guess and try.
     There is rule of thumb:

     1.   The bus and InPort mice always use busmouse protocol regardless of
          the brand of the mouse.
     2.   The ps/2 protocol should always be specified for the PS/2 mouse
          regardless of the brand of the mouse.
     3.   You must specify the auto protocol for the USB mouse.
     4.   Most 2-button serial mice support the microsoft protocol.
     5.   3-button serial mice may work with the mousesystems protocol.  If it
          does not, it may work with the microsoft protocol although the third
          (middle) button will not function.  3-button serial mice may also
          work with the mouseman protocol under which the third button may
          function as expected.
     6.   3-button serial mice may have a small switch to choose between
          ``MS'' and ``PC'', or ``2'' and ``3''.  ``MS'' or ``2'' usually mean
          the microsoft protocol.  ``PC'' or ``3'' will choose the
          mousesystems protocol.
     7.   If the mouse has a roller or a wheel, it may be compatible with the
          intellimouse protocol.

     To test if the selected protocol type is correct for the given mouse,
     enable the mouse pointer in the current virtual console,

           vidcontrol -m on

     start the mouse daemon in the foreground mode,

           moused -f -p _selected_port_ -t _selected_protocol_

     and see if the mouse pointer travels correctly according to the mouse
     movement.  Then try cut & paste features by clicking the left, right and
     middle buttons.  Type ^C to stop the command.

   Multiple Mice
     As many instances of the mouse daemon as the number of mice attached to
     the system may be run simultaneously; one instance for each mouse.  This
     is useful if the user wants to use the built-in PS/2 pointing device of a
     laptop computer while on the road, but wants to use a serial mouse when
     s/he attaches the system to the docking station in the office.  Run two
     mouse daemons and tell the application program (such as the X Window
     System) to use sysmouse(4), then the application program will always see
     mouse data from either mouse.  When the serial mouse is not attached, the
     corresponding mouse daemon will not detect any movement or button state
     change and the application program will only see mouse data coming from
     the daemon for the PS/2 mouse.  In contrast when both mice are attached
     and both of them are moved at the same time in this configuration, the
     mouse pointer will travel across the screen just as if movement of the
     mice is combined all together.

           moused -p /dev/cuad0 -i type

     Let the moused utility determine the protocol type of the mouse at the
     serial port /dev/cuad0.  If successful, the command will print the type,
     otherwise it will say ``unknown''.

           moused -p /dev/cuad0
           vidcontrol -m on

     If the moused utility is able to identify the protocol type of the mouse
     at the specified port automatically, you can start the daemon without the
     -t option and enable the mouse pointer in the text console as above.

           moused -p /dev/mouse -t microsoft
           vidcontrol -m on

     Start the mouse daemon on the serial port /dev/mouse.  The protocol type
     microsoft is explicitly specified by the -t option.

           moused -p /dev/mouse -m 1=3 -m 3=1

     Assign the physical button 3 (right button) to the logical button 1 (log-
     ical left) and the physical button 1 (left) to the logical button 3 (log-
     ical right).  This will effectively swap the left and right buttons.

           moused -p /dev/mouse -t intellimouse -z 4

     Report negative Z axis movement (i.e., mouse wheel) as the button 4
     pressed and positive Z axis movement (i.e., mouse wheel) as the button 5

     If you add

           ALL ALL = NOPASSWD: /usr/bin/killall -USR1 moused

     to your /usr/local/etc/sudoers file, and bind

           killall -USR1 moused

     to a key in your window manager, you can suspend mouse events on your
     laptop if you keep brushing over the mouse pad while typing.

     The moused utility does not currently work with the alternative console
     driver pcvt(4).

     Many pad devices behave as if the first (left) button were pressed if the
     user ``taps'' the surface of the pad.  In contrast, some ALPS GlidePoint
     and Interlink VersaPad models treat the tapping action as fourth button
     events.  Use the option ``-m 1=4'' for these models to obtain the same
     effect as the other pad devices.

     Cut and paste functions in the virtual console assume that there are
     three buttons on the mouse.  The logical button 1 (logical left) selects
     a region of text in the console and copies it to the cut buffer.  The
     logical button 3 (logical right) extends the selected region.  The logi-
     cal button 2 (logical middle) pastes the selected text at the text cursor
     position.  If the mouse has only two buttons, the middle, `paste' button
     is not available.  To obtain the paste function, use the -3 option to
     emulate the middle button, or use the -m option to assign the physical
     right button to the logical middle button: ``-m 2=3''.

     The moused utility partially supports ``Plug and Play External COM Device
     Specification'' in order to support PnP serial mice.  However, due to
     various degrees of conformance to the specification by existing serial
     mice, it does not strictly follow the version 1.0 of the standard.  Even
     with this less strict approach, it may not always determine an appropri-
     ate protocol type for the given serial mouse.

     The moused utility first appeared in FreeBSD 2.2.
