[nos-bbs] AXUI mode not showing all incoming UI frames

[Michael Curry]

Okay, hypothesis proven:

I inserted some logging statements at a couple of points in ax_recv(), and
have determined that UI frames that contain digis that don't have their H
bits set get discarded at around line 670 (where the comment says "Discard
if not forwarded"). Which is probably the right behavior if JNOS is only
functioning (with respect to UI-frames) as a digipeater, but which I
believe *isn't* right if it's also functioning as an unproto client.

Maiko (or someone): can I get an "Amen" for that belief?

Thanks,

KI6TYV, Michael

This cat is pushing a watermelon out of a lake. Your argument is invalid.
