It is the raw encoder/decoder of the SMPP 3.4 stream. In spite of the influence of the smpp34pdu project (https://github.com/essiene/smpp34pdu), this library was developed "from stratch", according to the "Short Message Peer-to-Peer Protocol Specification v3.4". This library is just a coder and decoder of the binary sequences and does not include any connection logic. Such functionality is planned as the separate project.
