41 is a pseudo-device driver that allows several
43 input devices to have their events multiplexed into one stream.
45 The typical usage for this device is to have two multiplexors, one
46 for mouse events and one for keyboard events. All
48 devices should direct their events to the mouse mux (normally 0)
49 and all keyboard devices, except the console, should direct their
50 events to the keyboard mux (normally 1). A device will
51 send its events to the mux indicated by the
53 locator. If none is given the device will not use a multiplexor.
54 The keyboard multiplexor should be connected to the display, using
57 command. It will then receive all keystrokes from all keyboards
58 and, furthermore, keyboards can be dynamically attached and detached without
59 further user interaction.
60 In a similar way, the window system will open the mouse multiplexor
61 and receive all mouse events; mice can also be dynamically attached

70 It is also possible to inject events into a multiplexor from a

79 there is a control device
81 The control device has a minor number 128 greater than the regular
82 mux device. It can be used to control the mux even when it is open,
