pcppi -- PC (ISA) control port driver SYNOPSIS
pcppi* at acpi? pcppi* at isa? isabeep* at pcppi? (alpha only) sysbeep* at pcppi? (i386 only) spkr0 at pcppi? midi* at pcppi? DESCRIPTION
The pcppi driver handles resource allocation and device attachment for the ports related to the ISA speaker in the traditional PC/AT ``design''. These are the ``system control port'' (which was implemented by the 8255 ``PPI'' in the XT, hence the name of this driver) at IO address 0x61. When associated with an attimer(4) device, it is possible to change the pitch of the sounds emitted through pcppi. The pcppi driver provides its child devices with the ability to output simple tones through the PC speaker. The speaker(4) and midi(4) devices use this to synthesize sounds. The isabeep(4) and sysbeep(4) devices are helpers which the pckbd(4) driver uses as a substitute for a ``keyboard beep'', because the PC keyboard hardware doesn't provide this. SEE ALSO

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). The builtin mappings are at this time: option wsconsctl language KB_US us English/US keyboard mapping (default) KB_UK uk English/UK keyboard mapping KB_BE be Belgian KB_CZ cz Czech (QWERTY) KB_DK dk Danish with ``dead accents'' KB_NL nl Dutch KB_FI fi Finnish KB_FR fr French KB_DE de German with ``dead accents'' KB_GR gr Greek KB_HU hu Hungarian KB_IT it Italian KB_JP jp Japanese KB_NO no Norwegian with ``dead accents'' KB_PL pl Polish KB_PT pt Portuguese KB_RU ru Russian KB_ES es Spanish KB_SV sv Swedish with ``dead accents'' KB_SF sf Swiss French KB_SG sg Swiss German KB_UA ua Ukrainian 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 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 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 simul- taneously, 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. SEE ALSO

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