The problem is that it doesn t seem like there are many PDP-11 or VAX
communications interfaces that actually implement this. The DMR and DMC
appear to, but as far as I can find those are the only ones. In
particular there don t appear to be any QBUS interfaces that can do
it. Have I missed any? Has anybody ever done this? What interface
did you use?
I thought the DELQA did? I don't think the DEQNA did, however.
Also, the DEUNA and DELUA handles it, as far as I know.
