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

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