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

[R. Voorhorst]

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.
