           This command will replace the former regRaw. It allows to set register
           in raw format. Its main purpose is to restore a complete register list
           to values secured before. <br>

           Dieser Befehl ersetzt das bisherige regRaw. Er erlaubt Register mit Rohdaten zu
           beschreiben. Hauptzweck ist das komplette Wiederherstellen eines zuvor gesicherten
           Registers. <br>
