pckbd -- PC keyboard driver for wscons
pckbc* at isa?
pckbd* at pckbc?
wskbd* at pckbd? console ?
This driver supports PC/AT keyboards within the wscons(4) console frame-
work. 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 map-
pings 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
KB_US|KB_COLEMAK us.colemak English/US keyboard with
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 func-
To set a German keyboard layout without ``dead accents'' and sending an
ESC character before the key symbol if the ALT key is pressed simultane-
ously, 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.

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