    Hi,

    Riley gave you a good explanation on the other issues. However a
    quick note about modulo-128.

    You can tell modulo-128 frames (connections) from regular by the
    "EAX25" text at the start of the line. Like this:

      1: EAX25: fm OH2BNS to OH2RBI-1 ctl SABME+ 16:51:43

    Also note that for EAX25 the sequence number display is pretty much
    broken in listen. As the numbers are simply concatenated you can not
    tell which belongs to which...

    In my opinion the old xNOS style AX.25 dump was much more readable
    _and_ consistent with the other protocol dumps in listen. But that's
    just me...
