.Nd PC keyboard driver for wscons
|
|
.Sh SYNOPSIS
|
|
.Cd pckbc* at isa?
|
|
.Cd pckbd* at pckbc?
|
|
.Cd "wskbd* at pckbd? console ?"
|
|
.Cd options PCKBD_LAYOUT=XXX
|
|
.Sh DESCRIPTION
|
|
This driver supports PC/AT keyboards within the
|
|
.Xr wscons 4
|
|
console framework. It doesn't provide direct device
|
|
driver entry points but makes its functions available via
|
|
the internal
|
|
.Xr wskbd 4
|
|
interface.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports a number of different key mappings which
|
|
can be chosen from with the kernel option
|
|
.Li PCKBD_LAYOUT
|
|
at compile time or with the utility
|
|
.Xr wsconsctl 8
|
|
(variable:
|
|
.Dq encoding )
|
|
at runtime.
|
|
Other mappings can be used if the whole keymap is replaced by means of
|
|
.Xr wsconsctl 8 .
|
|
The builtin mappings are at this time:
|
|
.Bl -column " KB_US|KB_DVORAK" "wsconsctl" "language"
|
|
.It Sy "option" Ta Sy "wsconsctl" Ta Sy "language"
|
|
.It Li KB_US Ta us Ta English/US keyboard mapping (default)
|
|
.It Li KB_DE Ta de Ta German with
|
|
.Dq dead accents
|
|
.It Li KB_FR Ta fr Ta French
|
|
.It Li KB_DK Ta dk Ta Danish with
|
|
.Dq dead accents
|
|
.It Li KB_IT Ta it Ta Italian
|
|
.It Li KB_UK Ta uk Ta British
|
|
.It Li KB_JP Ta jp Ta Japanese
|
|
.It Li KB_SV Ta sv Ta Swedish with
|
|
.Dq dead accents
|
|
.It Li "KB_US|KB_DECLK" Ta \&us.declk Ta English/US mapping for Tn DEC
|
|
.It Ta Ta LK400-style keyboards with PC keyboard
|
|
.It Ta Ta interface (e.g., LK461)
|
|
.It Li "KB_US|KB_DVORAK" Ta us.dvorak Ta English/US keyboard with
|
|
.It Ta Ta Do Dvorak Dc layout
|
|
.It Li KB_NO Ta no Ta Norwegian with
|
|
.Dq dead accents
|
|
.It Li KB_PT Ta pt Ta Portuguese
|
|
.It Li KB_ES Ta es Ta Spanish
|
|
.El
|
|
.Pp
|
|
The
|
|
.Li KB_DE ,
|
|
.Li KB_DK ,
|
|
.Li KB_NO
|
|
and
|
|
.Li KB_SV
|
|
mappings can be used in the
|
|
.Li KB_NODEAD (
|
|
.Dq .nodead )
|
|
variant. This switches off the
|
|
.Dq dead accents .
|
|
.Pp
|
|
The
|
|
.Li KB_US ,
|
|
.Li KB_JP
|
|
and
|
|
.Li KB_US|KB_DVORAK
|
|
mappings can be modified
|
|
to swap the left CTRL and the CAPS LOCK keys by the
|
|
.Li KB_SWAPCTRLCAPS
|
|
variant bit or the
|
|
.Dq .swapctrlcaps
|
|
suffix.
|
|
.Pp
|
|
The
|
|
.Li KB_METAESC (
|
|
.Dq .metaesc )
|
|
option can be applied to any layout. If set, keys pressed together
|
|
with the ALT modifier are prefixed by an ESC character. (Standard
|
|
behaviour is to add 128 to the ASCII value.)
|
|
.Pp
|
|
Because PC keyboard hardware doesn't contain a beeper, requests for
|
|
.Dq keyboard beeps
|
|
cannot be handled directly. On alpha and i386 a helper device attached
|
|
to the
|
|
.Xr pcppi 4
|
|
driver allows the use of the standard ISA speaker for this purpose.
|
|
On acorn32,
|
|
.Xr vidcaudio 4
|
|
performs this function.
|
|
.Sh EXAMPLES
|
|
To set a German keyboard layout without
|
|
.Dq dead accents
|
|
and sending an ESC character before the key symbol if the ALT
|
|
key is pressed simultaneously, use
|
|
.Ic wsconsctl Fl w Ar encoding=de.nodead.metaesc .
|
|
To set it at kernel build time, add
|
|
.Cd options PCKBD_LAYOUT="(KB_DE | KB_NODEAD | KB_METAESC)"
|
|
.br
|
|
to the kernel configuration file.

.Sh BUGS
|
|
The list of builtin mappings doesn't follow any logic.
|
|
It grew as people submitted what they needed.
