KBD(4)

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(1) 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.
