I sure tried to read as closely as I could and do exactly what I understood ! The fact that I wonder why anyone would like to reverse bytes did not stop me from doing so myself...

that bit of information is new to me, only did programming on mac (and atari, way back), don't normally come close to pentium machines, but that has nothing to do with that I followed the specs, it says for every field whether hi or lo byte is first, that is pretty clear, although I don't understand why a protocol would mix both representations..
I guess there must be some historical reasons of some sort, some hardware reasons.. ?

as listed in the specs (page 8) I send to 2.255.255.255 (or 10.255.255.255) with the jumper).
255.255.255.255 is pretty crazy, no ?


but what the about that first 8-char string, is that 'big endian' too ?
