Could you send me traces of the PyDECnet issues you're seeing? I have never seen a VMS DDCMP, but I've run the PyDECnet DDCMP against several others and it all works without the sort of troubles you mentioned. I'd like to understand what the problem is and if PyDECnet either needs a bugfix, or a workaround for a VMS bug.

Some day I may do at least partial Phase V in PyDECnet. Not soon, it's a big job.

Hi Paul,

Yes, I will let you know after I've looked into it further. My gut feel is it's something in the TCP session setup (maybe just a config issue) between simh and PyDecnet.
