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.  Oth-
     er mappings can be used if the whole keymap is replaced by means of
     wsconsctl(8).  The builtin mappings are at this time:

     KB_US   (for wsconsctl: ``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 (eg LK461).

     KB_US | KB_DVORAK ( ``us.dvorak'' ) English / US keyboard with ``Dvorak''
             layout.

     The KB_DE, KB_DK 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 CNTL     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 to use the standard ISA
     speaker for this purpose.


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 simul-
     tanously, use wsconsctl -w encoding=de.nodead.metaesc.  To set it at ker-
     nel 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 logics.  It grew as peo-
     ple submitted what they needed.
