Probably because ax25_get_info reads kernel internal tables that could be
changed from an interrupt. You would crash the kernel nicely if you
happened to be just reading an ax25 control block that is suddenly
removed from an interrupt...

IMHO TNT is broken in this case. Why does it need to read it so often? Ah,
don't tell me, the DOS version shows that info too...? ;)

Why is that confusing? Timed out _is_ timed out.

This on the other hand is under concideration already. It is possible
Craig has already written some code, I don't know. Anyway it will be only
error messages that are specific to libax25, eg. "Invalid callsign", "Port
xxx not active" etc.
