.Dd $Mdocdate: June 26 2008 $ .Dt WSMUX 4 .Os .Sh NAME .Nm wsmux .Nd console keyboard/mouse multiplexor for wscons .Sh SYNOPSIS .Cd "wskbd* at ... mux N" .Cd "wsmouse* at ... mux N"
p .Cd "pseudo-device wsmux" Op Ar count .Sh DESCRIPTION The .Nm is a pseudo-device driver that allows several .Xr wscons 4 input devices to have their events multiplexed into one stream.
p The typical usage for this device is to have two multiplexors, one for mouse events and one for keyboard events. All .Xr 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 .Va mux locator. If none is given, the device will not use a multiplexor. The keyboard multiplexor should be connected to the display, using the .Xr 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.
p It is also possible to inject events into a multiplexor from a user program. This is used by the .Xr wsmoused 8 daemon to take data from a mouse connected to a serial port and make it appear on the standard mouse mux. .Sh FILES l -item -compact t
