NAME

       setleds - set the keyboard leds

SYNOPSIS

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

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.
