[HECnet] native Dup sync line revisited --> preliminary tests reveals problems --> test setup?

Hi Paul, How was this tested: 11M+ to 11M+ or 11M+ to PyDecnet?

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. paul
