    svn rev 1181:

    • FCS/CRC is now inverted
    • MD-FCS validation changed (compare locally computed crc to packet crc instead of comparing to 0)
    • introduced constants INITFCS (0xFFFFFFFF) and SIZE_OF_FCS
      Still open: Shouldn't the protocol version change?
      -> next release is incompatible to TRDP stack versions 1.0 and 1.1

    Proto-version stays at 1.0 (decision by AHG/GH...)
