/**
 * @page TellStickNet TellStick Net protocol
 *
 * \section Introduction
 *
 * TellStick Net will eventually support local access through the LAN. This is
 * unsupported by Telldus Technologies but can be useful in some cases. For
 * instance in mobile devices or when the internet is not available. Using
 * TellStick Net through Telldus Live! is still the prefered and supported
 * method.
 *
 * This interface is still under development and is not ready for production.
 *
 * \section autodiscovery Auto discovery
 *
 * The TellStick Net can be auto discovered on the LAN using UDP broadcast.
 * Sending a package to the broadcast address 255.255.255.255 port 30303 will
 * be responded by any TellStick Net on the network. The packet should only
 * contain the single character 'D' (ascii number 68).
 *
 * The response from the device will be sent back to the same host and port as
 * the originated packet. So any dynamically port can be assigned by the host
 * implementing the auto discovery.
 * The returning packet is constructed in the following way:
 * <tt>product:mac address:activation code:firmware</tt>
 *
 * Example:<br>
 * <tt>TellStickNet:ABCDEFGHIJKL:ABDCEFGHIJ:2</tt><br>
 * Product: <tt>TellStick Net (TSNET)</tt><br>
 * Mac address: <tt>AB:CD:EF:GH:IJ:KL</tt><br>
 * Code for activation: <tt>ABCDEFGHIJ</tt><br>
 * Firmware version: <tt>2</tt>
 *
 * Use the source ip-address to determine the address to the device.
