It doesn't provide direct device 42driver entry points but makes its functions available via 43the internal 44.Xr wskbd 4 45interface. 46.Pp 47The 48.Nm 49driver supports a number of different key mappings which 50can be chosen from with the kernel option 51.Li PCKBD_LAYOUT 52at compile time or with the utility 53.Xr wsconsctl 8 54(variable: 55.Dq encoding ) 56at runtime. 57Other mappings can be used if the whole keymap is replaced by means of 58.Xr wsconsctl 8 . 59The builtin mappings are at this time: 60.Bl -column " KB_US|KB_DVORAK" "wsconsctl" "language" 61.It Sy "option" Ta Sy "wsconsctl" Ta Sy "language" 62.It Li KB_US Ta us Ta English/US keyboard mapping (default) 63.It Li KB_DE Ta de Ta German with 64.Dq dead accents 65.It Li KB_FR Ta fr Ta French 66.It Li KB_DK Ta dk Ta Danish with 67.Dq dead accents 68.It Li KB_IT Ta it Ta Italian 69.It Li KB_UK Ta uk Ta British 70.It Li KB_JP Ta jp Ta Japanese 71.It Li KB_SV Ta sv Ta Swedish with 72.Dq dead accents 73.It Li "KB_US|KB_DECLK" Ta \&us.declk Ta English/US mapping for 74.Tn DEC 75LK400-style keyboards 76.It Ta Ta with PC keyboard interface (e.g., LK461) 77.It Li "KB_US|KB_DVORAK" Ta us.dvorak Ta English/US keyboard with 78.Dq Dvorak 79layout 80.El 81.Pp 82The 83.Li KB_DE , 84.Li KB_DK 85and 86.Li KB_SV 87mappings can be used in the 88.Li KB_NODEAD ( 89.Dq .nodead ) 90variant. This switches off the 91.Dq dead accents . 92.Pp 93The 94.Li KB_US , 95.Li KB_JP 96and 97.Li KB_US|KB_DVORAK 98mappings can be modified 99to swap the left CTRL and the CAPS LOCK keys by the 100.Li KB_SWAPCTRLCAPS 101variant bit or the 102.Dq .swapctrlcaps 103suffix. 104.Pp 105The 106.Li KB_METAESC ( 107.Dq .metaesc ) 108option can be applied to any layout. If set, keys pressed together 109with the ALT modifier are prefixed by an ESC character. (Standard 110behaviour is to add 128 to the ASCII value.) 111.Pp 112Because PC keyboard hardware doesn't contain a beeper, requests for 113.Dq keyboard beeps 114cannot be handled directly. On alpha and i386 a helper device attached 115to the 116.Xr pcppi 4 117driver allows to use the standard ISA speaker for this purpose. 118.Sh EXAMPLES 119To set a German keyboard layout without 120.Dq dead accents 121and sending an ESC character before the key symbol if the ALT 122key is pressed simultaneously, use 123.Ic wsconsctl Fl w Ar encoding=de.nodead.metaesc . 124To set it at kernel build time, add 125.Cd options PCKBD_LAYOUT="(KB_DE | KB_NODEAD | KB_METAESC)" 126.br 127to the kernel configuration file. 128.Sh SEE ALSO 129.Xr isa 4 , 130.Xr pcppi 4 , 131.Xr wskbd 4 , 132.Xr wsconsctl 8 133.Sh BUGS 134The list of builtin mappings doesn't follow any logics. 135It grew as people submitted what they needed. 136
