I am checking my configs do to a similar problem...(in a different thread)The 6th argument in the axports line is an arbitrary description and
will not affect anything, except as a source of confusion.
The thing to note is the way the scripts set up ax.25 packet is udr0 is
the left mDin6 connector & udr1 is the right mDin6 connector. For your
case I'm assuming you are using the left mDin6 connnector and we will
just ignore udr1, the right connector for the time being.
