# NAME

`kbd` — Sun workstation keyboard

# SYNOPSIS

`kbd0 at zstty?`

# DESCRIPTION

The `kbd` driver provides an interface to the workstation console keyboard. "type 2", "type 3", "type 4", and "type 5" keyboards are supported. The "type 5" keyboard is treated as if it were a "type 4". All types generate keycodes encoding the key identity and motion (up or down) as the keys are pressed and released. The `kbd` driver either passes the keycodes to an application as they come in, or translates them into ASCII characters first according to a set of built-in tables.

If the keyboard is configured as the device to be used for system console input, it will be internally connected to the /dev/console device special file, which can be used as a tty(4) device.

The device special file /dev/kbd is used to get direct access to the keyboard input stream. The following ioctl's are supported (mostly just enough to keep the `X` server going):

KIOCTRANS
  Set translation mode. The argument is of type int *, the only value supported is `TR_UNTRANS_EVENT`.
KIOCGTRANS
  Get translation mode. The argument is of type int *. `TR_UNTRANS_EVENT` is always returned.
KIOCGETKEY
  Fill in old-style key station translation. The argument is of type struct okiockey *.
KIOCCMD
  Send a command to the keyboard. The argument is of type int *, and can have one of the following values:
  KBD_CMD_BELL
    Start the keyboard beeper.
  KBD_CMD_NOBELL
    Stop the keyboard beeper.
  KBD_CMD_CLICK
    Instruct the keyboard to make extra noise when touching keys.
  KBD_CMD_NOCLICK
    Instruct the keyboard to stop making extra noise when touching keys.
KIOCTYPE
  Get keyboard type. The argument is of type int *, in which one of the values `KB_SUN2`, `KB_SUN3` or `KB_SUN4` will be returned.
KIOCSDIRECT
  Route the keyboard input stream through the SunOS compatible event module. The argument is of type int *, a non-zero value will put the driver into “event” mode, while a value of zero will make it return to “ASCII translation” mode.
KIOCSKEY
  Set key station translation. The argument is of type struct kiockey * (see /usr/include/machine/kbio.h for more details).
KIOCGKEY
  Get key station translation. The argument is of type struct kiockey *.
KIOCLAYOUT
  Get keyboard layout (“type 4” only). The argument is of type int *, in which the uninterpreted result of the `KBD_CMD_GLAYOUT` keyboard command is returned (on `KBDUN4` type keyboards this will be the setting of a DIP switch bank).
KIOCSLED
  Set LED state (“type 4” only). The argument is of type char *, and is the inclusive OR of the following flags:

  LED_NUM_LOCK
  LED_COMPOSE
  LED_SCROLL_LOCK
  LED_CAPS_LOCK

  Each of these flags turn on the LED in the obvious key.

KIOCGLED
  Get LED state (“type 4” only). The argument is of type char *, in which the current LED state is returned.
