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

I think he did both M= to M+ as to PyDecnet, but the sentence " I don't understand this because the code is clearly there in the emulator, so apparently it's not being hit."is intriguing ... :)

Certainly sounds like Paul was doing M+ to PyDECnet. Not sure what more combinations he might have been playing with.
