NetBSD 6.1.5 - man page for wsmuxctl (netbsd section 4)

WSMUX(4)			   BSD Kernel Interfaces Manual 			 WSMUX(4)

     wsmux -- console keyboard/mouse multiplexor for wscons

     wskbd*   at ... mux 1
     wsmouse* at ... mux 0

     pseudo-device wsmux

     The wsmux is a pseudo-device driver that allows several wscons(4) input devices to have
     their events multiplexed into one stream.

     The typical usage for this device is to have two multiplexors, one for mouse events and one
     for keyboard events.  All wsmouse(4) devices should direct their events to the mouse mux
     (normally 0) and all keyboard devices, except the console, should direct their events to the
     keyboard mux (normally 1).  A device will send its events to the mux indicated by the mux
     locator.  If none is given the device will not use a multiplexor.	The keyboard multiplexor
     should be connected to the display, using the wsconscfg(8) command.  It will then receive
     all keystrokes from all keyboards and, furthermore, keyboards can be dynamically attached
     and detached without further user interaction.  In a similar way, the window system will
     open the mouse multiplexor and receive all mouse events; mice can also be dynamically
     attached and detached.

     If a wskbd(4) or wsmouse(4) device is opened despite having a mux it will be detached from
     the mux.

     It is also possible to inject events into a multiplexor from a user program.

     For each mux device, /dev/wsmuxN there is a control device /dev/wsmuxctlN.  The control
     device has a minor number 128 greater than the regular mux device.  It can be used to con-
     trol the mux even when it is open, e.g., by wsmuxctl(8).
