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).
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, 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.
