It is attached to the hardware specific keyboard drivers and 54provides their connection to 55.Dq wsdisplay 56devices and a character device interface. 57.Pp 58The common keyboard support consists of: 59.Bl -bullet 60.It 61Mapping from keycodes (defined by the specific keyboard driver) to 62keysyms (hardware independent, defined in 63.Pa /usr/include/dev/wscons/wsksymdef.h ) . 64.It 65Handling of 66.Dq compose 67sequences. Characters commonly not present as separate key on keyboards 68can be generated after either a special 69.Dq compose 70key is pressed or a 71.Dq dead accent 72character is used. 73.It 74Certain translations, like turning an 75.Dq ALT 76modifier into an 77.Dq ESC 78prefix. 79.It 80Automatic key repetition 81.Pq Dq typematic . 82.It 83Parameter handling for 84.Dq keyboard bells . 85.It 86Generation of 87.Dq keyboard events 88for use by X servers. 89.El 90.Pp 91The 92.Nm 93driver provides a number of ioctl functions to control key maps 94and other parameters. These functions are accessible though the 95associated 96.Dq wsdisplay 97device as well. A complete list is in 98.Pa /usr/include/dev/wscons/wsconsio.h . 99The 100.Xr wsconsctl 8 101utility allows to access key maps and other variables. 102.Pp 103The 104.Em console 105locator in the configuration line refers to the device's use as input 106part of the operating system console. A device specification containing 107a positive value here will only match if the device is in use as system 108console. (The console device selection in early system startup is not 109influenced.) This way, the console device can be connected to a known 110wskbd device instance. 111.Sh FILES 112.Bl -item 113.It 114.Pa /dev/wskbd* 115.It 116.Pa /usr/include/dev/wscons/wsksymdef.h 117.It 118.Pa /usr/include/dev/wscons/wsconsio.h . 119.El 120.Sh SEE ALSO 121.Xr pckbd 4 , 122.Xr ukbd 4 , 123.Xr wscons 4 , 124.Xr wsmux 4 , 125.Xr wsconsctl 8 , 126.Xr wskbd 9 127
