<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 using <code>msg.udpport</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 is 9.</p>
