             * Ports are simple lines for input or output of audio to or from audio devices.
             * Common examples of ports that act as source lines (mixer inputs) include the microphone,
             * line input, and CD-ROM drive.  Ports that act as target lines (mixer outputs) include the
             * speaker, headphone, and line output.  You can access port using a <code>{@link Port.Info}</code>
             * object.
