    It won't be in the ax25 daemon config file. But it's easily fixed.

    You are probably using an exponential back-off scheme. This means, the
    interval between SABM attempts keeps doubling. I have a feeling this is
    the default.

    Suggest you go to "linear" back-off (which is in reality a fixed interval),
    and set your frame acknowledge time (FRACK) short enough for the
    ISS/PCSAT pass.

    All this is done by writing numbers to a bunch of files, and it is probably
    mentioned in the ax25 howto. From my fast-fading memory, it is in
    /dev/proc/ax25/<interface_name>/

    John, N8UR, has an excellent web site at:

    http://www.febo.com/linux-ax25/

    Look for the "axdispparms" utilities, these are a set of shell scripts that will
    let you view and change the interface parameters on the fly. Call the
    script from the end of your ax25 startup script to set the params to
    whatever you fancy.

    Sorry, can't help with that. I have gone back to kernel 2.2.19

    The BayCom modem is not the problem. The parameters are. No need to
    buy a TNC.
