+ * List of control codes:
+ * https://en.wikipedia.org/wiki/C0_and_C1_control_codes
+ *
+ * This encoder can be used to achieve a basic transport layer when using
+ * char based transmission systems.
+ * The passed source strean is converted into a encoded stream by adding
+ * a STX marker at the start of the stream and an ETX marker at the end of
+ * the stream. Any STX, ETX, DLE and CR occurrences in the source stream are
+ * escaped by a DLE character. The encoder also replaces escaped control chars
+ * by another char, so STX, ETX and CR should not appear anywhere in the actual
+ * encoded data stream.
+ *
+ * When using a strictly char based reception of packets encoded with DLE,
+ * STX can be used to notify a reader that actual data will start to arrive
+ * while ETX can be used to notify the reader that the data has ended.

+ * The MessageQueue should be used as "post box" for a single owning object.
+ * So all message queue communication is "n-to-one".
+ * For creating the queue, as well as sending and receiving messages, the class
+ * makes use of the operating system calls provided.
+ *
+ * Please keep in mind that FreeRTOS offers different calls for message queue
+ * operations if called from an ISR.
+ * For now, the system context needs to be switched manually.
