[HECnet] DECnet-RT?

I THINK that DECnet RT had DMC-11 support in it. The Phase III support was going in after I left the RT group.? It was certainly the right time frame for it.

RSTS is different: it uses the standard device drivers, but with some additional I/O request function codes.? DMC use direct by applications was always supported.?
