.Sh NAME
.Nm pckbd
.Nd PC keyboard driver for wscons
.Sh SYNOPSIS
.Cd "pckbd* at pckbc?"
.Cd "pckbd* at gsckbc?" Pq hppa
.Cd "pckbd* at mkbc?" Pq sgi
.Cd "wskbd* at pckbd?"
.Cd "option 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
.Dq PCKBD_LAYOUT
at compile time or with the utility
.Xr wsconsctl 8
(variable:
.Dq keyboard.encoding )
at runtime.
Other mappings can be used if the whole keymap is replaced by means of
.Xr wsconsctl 8 .
The built-in mappings are at this time:
.Pp
.Bl -tag -width Ds -offset indent -compact

.It KB_UK

British.
.It KB_US
.Pq us
English/US keyboard mapping (default).
.It KB_US | KB_DECLK
.Pq us.declk
English/US mapping for
DEC LK400-style keyboards with PC keyboard interface (eg LK461).
.It KB_US | KB_DVORAK
.Pq us.dvorak
English/US keyboard with
.Dq Dvorak
layout.
.El
.Pp
The KB_DE, KB_DK, KB_IS, KB_NO, KB_SF, KB_SG, KB_SV and KB_TR
mappings can be used in the KB_NODEAD
.Pq .nodead
variant.
This switches off the
.Dq dead accents .
.Pp
The KB_BE, KB_FR, KB_FR | KB_DVORAK, KB_JP, KB_UK, KB_US and KB_US | KB_DVORAK
mappings can be modified
to swap the left Control and the Caps Lock keys by the
KB_SWAPCTRLCAPS variant bit or the
.Dq .swapctrlcaps
suffix.
.Pp
The KB_METAESC
.Pq .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 pcppi
driver allows use of the standard ISA speaker for this purpose.
.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 keyboard.encoding=de.nodead.metaesc .
To set it at kernel build time, add
the following to the kernel configuration file:
.Bd -literal -offset indent
option PCKBD_LAYOUT="(KB_DE|KB_NODEAD|KB_METAESC)"

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