setleds - set the keyboard leds
setleds [-v] [-L] [-D] [-F] [{+|-}num] [{+|-}caps] [{+|-}scroll]
setleds reports and changes the led flag settings of the current 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.
-F This is the default. Only change the VT flags (and their setting
may be reflected by the keyboard leds).
-D 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.
-L Do 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.
-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.)
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
In keyboard application mode the NumLock key does not influence the
NumLock flag setting.
