      Hi everyone!
      I don't know if anyone else have noted any abnormal problem with
    NEW-AX25, precisely about AX.25 Protocol behaviour, but I have two
    problems detected:

      1. Why the AX.25 doesn't send a confirmation DM when it receives a DISC?
         It just disconnects. The other station transmits DISCs until it
         reaches maximum retry count.
      2. Why the AX.25 doesn't send a DISC when a Setup Connection (SABM) is
         aborted? It could happen that the other station hears us and answers,
         but we don't hear him. in that case the other station stays with a
         connection with us.
      3. Well, I think this is other problem found so far related with error
         recovery in a connection. This is a bit dificult to explain I'll put
         a piece of log of a channel activity during a connection with errors:

    Sorry for the long piece of Log.
    Is this a normal behaviour during a connection with errors? I never saw
    this with Normal AX.25.

    BTW, These experiments were made with an YAM modem and thw Kernel was
    2.2.19 with NEW-AX.25 patched. I have also made experiments with a DK9RR
    modem (at 9600bps) connected in a PCISCC card. The results were the same.
