NAME

setleds - set the keyboard leds

SYNOPSIS

setleds[-v] [-L] [-D] [-F][{+|-}num] [{+|-}caps] [{+|-}scroll]

DESCRIPTION

Setledsreports and changes the led flag settings of a VT(namely NumLock, CapsLock and ScrollLock).Without arguments,setledsprints the current settings.With arguments, it sets or clears the indicated flags(and leaves the others unchanged). The settings beforeand after the change are reported if the -v flag is given.

The led flag settings are specific for each VT (and the VTcorresponding to stdin is used).

By default (or with option -F),setledswill only change the VT flags (and their setting may bereflected by the keyboard leds).

With option -D,setledswill 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,setledswill 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 commandsetleds -L(without further arguments) will restore the situation in whichthe leds reflect the VT flags.

One might usesetledsin /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 theinterpretation 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 keywhen 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/startsconsole output.)

BUGS

In keyboard application mode the NumLock key does notinfluence the NumLock flag setting.
