pckbd — PC
keyboard driver for wscons
pckbd* at pckbc?
pckbd* at gsckbc? (hppa)
wskbd* at pckbd?
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.
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
“keyboard.encoding”) at runtime. Other mappings can be used if
the whole keymap is replaced by means of
wsconsctl(8). The built-in mappings
are at this time:
The KB_DE, KB_DK, KB_IS, KB_NO, KB_SF, KB_SG, KB_SV and KB_TR mappings can be used in the KB_NODEAD (.nodead) variant. This switches off the “dead accents”.
The KB_BE, KB_FR, KB_FR | KB_DVORAK, KB_JP, KB_UK, KB_US, KB_US | KB_DVORAK and KB_US | KB_COLEMAK mappings can be modified to swap the left Control 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 driver allows use of the standard ISA speaker for this purpose.
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
keyboard.encoding=de.nodead.metaesc. To set it at kernel build time,
add the following to the kernel configuration file:
The list of built-in mappings doesn't follow any logic. It grew as people submitted what they needed.
