NAME
kbd —
Sun workstation keyboard
SYNOPSIS
pseudo-device kbd
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
(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 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.
