    ok. A little more work than one would expect but can be done.

    Anyway, I've changed my protocol  so a byte with a value like 255
means PacketStart. Now I can send any value between 0-254 (almost 8 bit
values) and just need to send an extra byte at the start of  the packet.
For large packets this would make the comunication a bit faster.

    Thank you very much,

    Brusque
