Wish I had heard that before we got rid of our RSX-11M-Plus system!

It's true our experience with DECnet/Linux is from VMS.  For the last decades we used the RSX system entirely from VMS using DECnet's Task-to-Task feature to access custom UNIBUS hardware on a PDP-11/73 with a QNIVERTER.

Do you know if a SIMH RSX system would be able duplicate the errors you are talking about?  Do you have any clue whether the problems are in the Linux device driver or the applications?  I know there are some configuration hoops one has to jump through that seem to change with every new Linux kernel.  I did some hacking there to get it working.  But, I never had to hack the applications.  That being said, the only one we care about is DAP.

Feel free to drop me a note off-list if you think it is worth pursuing.
