<script type="text/html" data-help-name="wake on lan">
    <p>Sends a Wake-On-LAN magic packet to the mac address specified.</p>
    <p>You may instead set <code>msg.mac</code> to dynamically set the target device mac to wake up.</p>
    <p>The address of the target machine can optionally be set using <code>msg.host</code></p>
    <p>You can likewise set the destination UDP port, number of packets sent, and interval between packets using <code>msg.udpport</code>, <code>msg.numpackets</code>, <code>msg.interval</code>.</p>
    <p>Setting the target address to the broadcast address of the subnet that the target machine is attached to works best.
    For a class C address this is usually just the first three parts of the ip address followed by 255. eg 192.168.1.255.</p>
    <p>You can specify the target UDP port (default 9), number of packets sent (default 3), and interval between packets (default 100ms).</p>
