Is this the dreaded xNOS-to-nonNOS link problem John?

What software variety is "the local node", and is there any hope it will
soon support fragmentation?

As an aside - I have generously played with parms on my station plus my
two local JNOS neighbors by 2-meter radio & 1200B.  All three of us
support fragmentation and some thru-put gain is to be had by utilizing
fragmentation techniques over the small paclen size setting.  Our
experience is that timer settings got in the way of "joy"...  Again -
fragmented packets work fine here within the JNOS family / vc is no
issue.

I have had no reason to look, but there may be a switch to disable
fragmentation support so it is on a par with non-nos nodes.  Without
fragmenting, your only option is to shrink MTU, paclen, ..., to
compatible numbers with your neighbors.  (right?)  I don't believe
initial link negotiation can settle all variation...
