description
Setleds
reports and changes the led flag settings of a VT (namely
NumLock, CapsLock and ScrollLock). Without arguments,
setleds prints the current settings. With arguments,
it sets or clears the indicated flags (and leaves the others
unchanged). The settings before and after the change are
reported if the -v flag is given.
The led flag
settings are specific for each VT (and the VT corresponding
to stdin is used).
By default (or
with option -F), setleds will only change the
VT flags (and their setting may be reflected by the keyboard
leds).
With option
-D, setleds will change both the VT flags and
their default settings (so that a subsequent reset will not
undo the change). This might be useful for people who always
want to have numlock set.
With option
-L, setleds will not touch the VT flags, but
only change the leds. From this moment on, the leds will no
longer reflect the VT flags (but display whatever is put
into them). The command setleds -L (without further
arguments) will restore the situation in which the leds
reflect the VT flags.
One might use
setleds in /etc/rc to define the initial and default
state of NumLock, e.g. by
INITTY=/dev/tty[1-8]
for tty in $INITTY; do
setleds -D +num <
$tty
done
options
-num
+num
Clear or set NumLock. (At
present, the NumLock setting influences the interpretation
of keypad keys. Pressing the NumLock key complements the
NumLock setting.)
-caps +caps
Clear or set CapsLock. (At
present, the CapsLock setting complements the Shift key when
applied to letters. Pressing the CapsLock key complements
the CapsLock setting.)
-scroll +scroll
Clear or set ScrollLock. (At
present, pressing the ScrollLock key (or ^S/^Q) stops/starts
console output.)
bugs
In keyboard
application mode the NumLock key does not influence the
NumLock flag setting.
