+        auszuf&uuml;hren.  Um diesen Zeitgeber zu entfernen sollte man das

+        auszuschalten.  Diese at Instanz ist sichtbar unter dem Namen

+        l&ouml;scht man diese at Definition.  </li>
+    <li>off-till &lt;timedet&gt<br>
+        siehe on-till.</li>
+    <li>blink &lt;anzahl&gt; &lt;blink-periode&gt;<br>
+        Das Ger&auml;t wird mit "on" f&uuml;r die &lt;blink-periode&gt;
+        eingeschaltet, und das wird nach &lt;blink-periode&gt; wiederholt. Um
+        das Blinken vorzeitig zu stoppen spezifiziert man "0 0" als

+        Das Ger&auml;t wird f&uuml;r die spezifizierten Intervalle
