WSMUX(4)                NetBSD Kernel Interfaces Manual               WSMUX(4)

NAME
     wsmux -- console keyboard/mouse multiplexor for wscons

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

     pseudo-device wsmux

DESCRIPTION
     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 key-
     boards 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 pro-
     gram.

FILES
     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 control the mux even when it
     is open, e.g., by wsmuxctl(8).
