Mostly right, thats during normal operations.  However, during
software downline loading from a VAX or PDP (or other?) host, and
during the infrequent software crash dump UPline load, they do speak
DECnet.  Also, they support remote console facility which I guess is
also DECnet...(thats NCP> CONNECT CONSOLE, check it out, nice for the
times when you have to forceably logout a locked-up port and the
terminal server in question is a long stroll away down the building!)
Point is, 'technically speaking' the beasties do speak both LAT and
DECnet, sometimes at the same time.
