SETLEDS(1)                  General Commands Manual                 SETLEDS(1)



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.
