.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver handles common tasks for keyboards within the
|
|
.Xr wscons 4
|
|
framework. It is attached to the hardware specific keyboard drivers and
|
|
provides their connection to
|
|
.Dq wsdisplay
|
|
devices and a character device interface.
|
|
.Pp
|
|
The common keyboard support consists of:
|
|
.Bl -bullet
|
|
.It
|
|
Mapping from keycodes (defined by the specific keyboard driver) to
|
|
keysyms (hardware independent, defined in
|
|
.Pa /usr/include/dev/wscons/wsksymdef.h ) .
|
|
.It
|
|
Handling of
|
|
.Dq compose
|
|
sequences. Characters commonly not present as separate key on keyboards
|
|
can be generated after either a special
|
|
.Dq compose
|
|
key is pressed or a
|
|
.Dq dead accent
|
|
character is used.
|
|
.It
|
|
Certain translations, like turning an
|
|
.Dq ALT
|
|
modifier into an
|
|
.Dq ESC
|
|
prefix.
|
|
.It
|
|
Automatic key repetition
|
|
.Pq Dq typematic .
|
|
.It
|
|
Parameter handling for
|
|
.Dq keyboard bells .
|
|
.It
|
|
Generation of
|
|
.Dq keyboard events
|
|
for use by X servers.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver provides a number of ioctl functions to control key maps
|
|
and other parameters. These functions are accessible though the
|
|
associated
|
|
.Dq wsdisplay
|
|
device as well. A complete list is in
|
|
.Pa /usr/include/dev/wscons/wsconsio.h .
|
|
The
|
|
.Xr wsconsctl 8
|
|
utility allows to access key maps and other variables.
|
|
.Pp
|
|
The
|
|
.Em console
|
|
locator in the configuration line refers to the device's use as input
|
|
part of the operating system console. A device specification containing
|
|
a positive value here will only match if the device is in use as system
|
|
console. (The console device selection in early system startup is not
|
|
influenced.) This way, the console device can be connected to a known
|
|
wskbd device instance.
