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

``ASCII translation''
mode.

-
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``.blm Pp only. '')
The argument is of type
int *
,
in which the uninterpreted result of the
