        Some newer Pioneer A/V models seem to run ONKYO's ISCP protocol as well and therefore should be fully supported by this module.<br>

        <br>
        Instead of IP address or hostname you may set a serial connection format for direct connectivity.<br>

In Case the device does not support the command, just nothing happens as normally the device does not send any response. In case the command is temporarily not available you may see according feedback from the log file using attribute verbose=4.
