PCKBD(4)                NetBSD Kernel Interfaces Manual               PCKBD(4)


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 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
                                       ``Dvorak'' layout
     KB_US|KB_COLEMAK     us.colemak   English/US keyboard with
                                       ``Colemak'' 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 func-
     tion.


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 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.

BUGS

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