console keyboard/mouse multiplexor for wscons
wskbd* at ... mux N
wsmouse* at ... mux N
is a pseudo-device driver that
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
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
locator. If none is given the device will
not use a multiplexor. The keyboard multiplexor should be connected to the
display, using the
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.
It is also possible to inject events into a multiplexor from a user program.
This is used by the
to take data from a mouse connected to a serial port and make it appear on the
standard mouse mux.
