 * void setUplinkHost(String $host, int $port, bool $ssl = false, String $bind = null)
 *     sets the Uplink connection information.
 *
 * void setLoopTimeout(int $timeout)
 *     sets the maximum time loop() is blocking the script execution.
 *
 * void setUplinkServer(int $numeric, String $name, String $password)
 *     sets the own P10 Server information.
