* This encoder can be used to achieve a basic transport layer when using

* 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.
