The following Linux-specific
|
|
|
|
.BR ioctl (2)
|
|
|
|
requests are supported.
|
2013-06-07 15:10:45 +00:00
|
|
|
Each requires a third argument, assumed here to be
|
|
|
|
.IR argp .

.TP
|
|
|
|
.B KDGETLED
|
2007-05-12 13:26:09 +00:00
|
|
|
Get state of LEDs.
|
2013-06-07 15:10:45 +00:00
|
|
|
.I argp
|
|
|
|
points to a
|
|
|
|
.IR char .
|
2007-04-12 22:42:49 +00:00
|
|
|
The lower three bits
|
2013-06-07 15:10:45 +00:00
|
|
|
of
|
|
|
|
.I *argp
|
|
|
|
are set to the state of the LEDs, as follows:

.TP
|

.B KDSETLED
|
2007-04-12 22:42:49 +00:00
|
|
|
Set the LEDs.
|
|
|
|
The LEDs are set to correspond to the lower three bits of
|
2013-06-07 15:10:45 +00:00
|
|
|
.IR argp .
|
2007-04-12 22:42:49 +00:00
|
|
|
However, if a higher order bit is set,
|
2004-11-03 13:51:07 +00:00
|
|
|
the LEDs revert to normal: displaying the state of the
|
|
|
|
keyboard functions of caps lock, num lock, and scroll lock.
|
|
|
|
.LP
|
|
|
|
Before 1.1.54, the LEDs just reflected the state of the corresponding
|
|
|
|
keyboard flags, and KDGETLED/KDSETLED would also change the keyboard
|
2007-04-12 22:42:49 +00:00
|
|
|
flags.
|
2013-06-07 15:10:45 +00:00
|
|
|
Since 1.1.54 the LEDs can be made to display arbitrary
|
2004-11-03 13:51:07 +00:00
|
|
|
information, but by default they display the keyboard flags.
|
2013-06-12 11:33:47 +00:00
|
|
|
The following two ioctls are used to access the keyboard flags.

2013-06-07 15:10:45 +00:00
|
|
|
.I argp

|
|
|
points to a char which is set to the flag state.
|
2004-11-03 13:51:07 +00:00
|
|
|
The low order three bits (mask 0x7) get the current flag state,
|

|
2008-06-28 04:57:20 +00:00

|
2004-11-03 13:51:07 +00:00

The low order three bits (mask 0x7) have the flag state,

and the low order bits of the next nibble (mask 0x70) have
|
2008-06-28 04:57:20 +00:00

|
|

The lower 16 bits of

|

|
|
specify the period in clock cycles,
|
2004-11-03 13:51:07 +00:00
|
|
|
and the upper 16 bits give the duration in msec.
|
2007-04-12 22:42:49 +00:00
|
|
|
If the duration is zero, the sound is turned off.
|
2004-11-03 13:51:07 +00:00
|
|
|
Control returns immediately.
|
2013-06-07 15:10:45 +00:00
|
|
|
For example,
|
|
|
|
.I argp
|
|
|
|
= (125<<16) + 0x637 would specify
|
2004-11-03 13:51:07 +00:00
|
|
|
the beep normally associated with a ctrl-G.

The current video adapter

2004-11-03 13:51:07 +00:00
|
|
|
register settings are saved, then the controller is programmed to turn off
|
2007-04-12 22:42:49 +00:00
|
|
|
the vertical synchronization pulses.
|
2006-12-27 03:54:41 +00:00
|
|
|
This puts the monitor into "standby" mode.
|
2007-04-12 22:42:49 +00:00
|
|
|
If your monitor has an Off_Mode timer, then
|
2004-11-03 13:51:07 +00:00

it will eventually power down by itself.

2004-11-03 13:51:07 +00:00

This puts the monitor into "off" mode.

If your monitor has no Off_Mode timer,

or if you want your monitor to power down immediately when the

Ioctl's are undocumented Linux internals, liable to be changed

|
|
|
without warning.

|
|
(And indeed, this page more or less describes the

situation as of kernel version 1.1.94;
|
|
|

there are many minor and not-so-minor

Very often, ioctls are introduced for communication between the
|
2004-11-03 13:51:07 +00:00
|
|
|
kernel and one particular well-known program (fdisk, hdparm, setserial,
|
|
|
|
tunelp, loadkeys, selection, setfont, etc.), and their behavior will be
|
|
|
|
changed when required by this particular program.
