Noticed something odd: the source address was broadcast. That's not valid, of course. The question is why that happened. The answer is that the emulation uses the address in slot 0 of the address filter as the source address. The hardware doesn't care what order the addresses go in as far as filtering is concerned; DECnet/E puts broadcast in slot 0 and the physical address in slot 1, followed by any multicast addresses. Is the SIMH behavior also what a real LQA does? That would be an interesting DECnet/E bug if so... Or does a real LQA just use the physical address, as a UNA would? Hi, Paul. Sorry for not responding sooner. Busy, as usual. However, I did mark this for some later investigation. However, I now realize that it's not trivial for me to test, as it would appear a RSTS/E system would help. :-) I honestly don't know how a real LQA do. Maybe John Wilson knows more, since he have been digging into these kind of questions way more than most people I know... Or else if you have some realistic suggestion on how I would test this on my machine, as I do have a 11/93 with a real LQA here (although an LQA plus). I can provide access to my RSTS/E machine with a DELQA if that would be helpful. Hello! Only if the occupants next to the machine who happened to be needing it to keep warm mean. Just six cats of both sizes. They do. But what's that big hairy something else doing outside your place? Gyrating suggestively. -Dave -- Dave McGuire, AK4HZ New Kensington, PA That word there should be "mind". (Fast keyboard and slow mind.) And the big hairy thing is trying to get someone out to play with. Supposedly there's enough stuff on the ground to drive everyone to distraction. Did anyone see the news concerning last week's asteroid strike in Russia? It's being blamed on someone who happens to be on our list.
