DECnet support for RT-11 is pretty bad (Phase III over
serial, IIRC),
I'm pretty sure it doesn't support LAT, but I could be wrong. I think
there might be a couple other DEC OS's that support it, but finding
anyone with a copy of them is nearly impossible.
LAT is not DECnet. You can have DECnet without LAT and LAT without
DECnet.
