So "full" presumably means that: the first octet of a packet is the start delimiter for the packet (the start delimiter appears not to have a single standard value for all packets, so it appears that it can't be elided without loss of information); it also includes the end delimiter for asynchronous transmission, and all the octets between the delimiters, including the FCS octet, exactly as they appear on the wire. _______________________________________________ tcpdump-workers mailing list tcpdump-workers@lists.tcpdump.org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers
