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 key- board 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 key- strokes from all keyboards and, furthermore, keyboards can be dynamically attached and detached without further user interaction. In a simi- lar 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. 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 regu- lar mux device. It can be used to control the mux even when it is open, e.g., by wsmuxctl(8). /dev/wsmouse a.k.a. /dev/wsmux0 /dev/wskbd a.k.a. /dev/wsmux1 /usr/include/dev/wscons/wsconsio.h SEE ALSO

WSKBD(4) BSD Kernel Interfaces Manual WSKBD(4) NAME
wskbd -- generic keyboard support in wscons SYNOPSIS
wskbd* at pckbd? console ? mux 1 (standard PC keyboard) wskbd* at ukbd? console ? mux 1 (USB keyboard) wskbd* at lkkbd? console ? mux 1 (DEC LK200/400 serial keyboard) wskbd0 at akbd? console ? mux 1 (Apple ADB keyboard) wskbd0 at nextkbd? console ? mux 1 (NeXT keyboard) wskbd* at vrkiu? console ? mux 1 (NEC VR4000 series HPC keyboard) wskbd* at skbd? console ? mux 1 (keyboard of misc hpcmips handheld devices) wskbd* at btkbd? console ? mux 1 (Bluetooth keyboard) DESCRIPTION
The wskbd driver handles common tasks for keyboards within the wscons(4) framework. It is attached to the hardware specific keyboard drivers and provides their connection to ``wsdisplay'' devices and a character device interface. The common keyboard support consists of: o Mapping from keycodes (defined by the specific keyboard driver) to keysyms (hardware independent, defined in /usr/include/dev/wscons/wsksymdef.h). o Handling of ``compose'' sequences. Characters commonly not present as separate key on keyboards can be generated after either a special ``compose'' key is pressed or a ``dead accent'' character is used. o Certain translations, like turning an ``ALT'' modifier into an ``ESC'' prefix. o Automatic key repetition (``typematic''). o Parameter handling for ``keyboard bells''. o Generation of ``keyboard events'' for use by X servers. The wskbd driver provides a number of ioctl functions to control key maps and other parameters. These functions are accessible though the associated ``wsdisplay'' device as well. A complete list is in /usr/include/dev/wscons/wsconsio.h. The wsconsctl(8) utility allows to access key maps and other variables. The console locator in the configuration line refers to the device's use as input part of the operating system console. A device specifica- tion containing a positive value here will only match if the device is in use as system console. (The console device selection in early sys- tem startup is not influenced.) This way, the console device can be connected to a known wskbd device instance. Ioctls The following ioctl(2) calls are provided by the wskbd driver or by devices which use it. Their definitions are found in dev/wscons/wsconsio.h. WSKBDIO_GTYPE Get the keyboard type. WSKBDIO_COMPLEXBELL, WSKBDIO_SETBELL, WSKBDIO_GETBELL, WSKBDIO_SETDEFAULTBELL, WSKBDIO_GETDEFAULTBELL (struct wsmouse_repeat) Get and set keyboard bell settings. WSKBDIO_SETKEYREPEAT, WSKBDIO_GETKEYREPEAT, WSKBDIO_SETDEFAULTKEYREPEAT, WSKBDIO_GETDEFAULTKEYREPEAT (struct wskbd_keyrepeat_data) Get and set keyboard autorepeat settings. WSKBDIO_SETLEDS, WSKBDIO_GETLEDS (int) Get and set keyboard LED settings. WSKBDIO_GETMAP, WSKBDIO_SETMAP (struct wskbd_map_data) Get and set keyboard keymapping settings. WSKBDIO_GETENCODING, WSKBDIO_SETENCODING (kbd_t) Get and set keyboard encoding settings. WSKBDIO_GETKEYCLICK, WSKBDIO_SETKEYCLICK (int) Get and set keyboard keyclick settings. WSKBDIO_SETVERSION (int) Set the wscons_event protocol version. The default is 0 for binary compatibility. The latest version is always available as WSKBD_EVENT_VERSION, and is currently 1. All new code should use a call similar to the below to ensure the correct version is returned. int ver = WSKBD_EVENT_VERSION; if (ioctl(fd, WSKBDIO_SETVERSION, &ver) == -1) err(EXIT_FAILURE, "cannot set version"); FILES
