kbd -- Sun workstation keyboard
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 gener-
ate 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 charac-
ters first according to a set of built-in tables.
If the keyboard is configured as the device to be used for system console
input (see eeprom(8)), 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 key-
board 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
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
KIOCGKEY Get key station translation. The argument is of type struct
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:
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.
eeprom(4), ms(4), eeprom(8)
kbd is hardwired to the built-in zs1 serial port at 1200 bps.
