More on this...

I built an M+ system with DUP lines, and unlike what was reported in this thread, I did NOT see problems talking to other things (like PyDECnet or DMC emulation) that expect plain data without frame length fields.  I don't see frame lengths in the trace.  

I don't understand this because the code is clearly there in the emulator, so apparently it's not being hit.  Not by DECnet/RSX anyway.  More to be studied.
