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.</div><div><br></div><div>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.</div><div><br></div><div>Feel free to drop me a note off-list if you think it is worth pursuing.</div><div><br><div><div><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: 'Lucida Grande'; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div style="font-size: 12px; ">Larry Baker</div><div style="font-size: 12px; ">US Geological Survey</div><div style="font-size: 12px; ">650-329-5608</div><div style="font-size: 12px; "><a href="mailto:baker@usgs.gov">baker@usgs.gov</a></div><div style="font-size: 12px; "><br></div></span></div><div></div></div></div></body></html>
