/*
 * xPL.Arduino v0.1, xPL Implementation for Arduino
 *
 * This code is parsing a xPL message stored in 'received' buffer
 * - isolate and store in 'line' buffer each part of the message -> detection of EOL character (DEC 10)
 * - analyse 'line', function of its number and store information in xpl_header memory
 * - check for each step if the message respect xPL protocol
 * - parse each command line
