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.

One "annoying" thing with DECnet under RSX is that this means you must
have a separate controller for serial ports if you want to talk DECnet
on any, and use others as normal terminal ports, since they cannot
co-exist on the same controller. Either the DECnet device driver
manages the controller, or the TTDRV device driver manages it. All
ports goes to one usecase or the other. Mixing is not possible...

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.? I'm not sure if application use
of Ethernet was supported, or whether it works (and if not, how hard
that would be to fix). > Paul Koning <paulkoning at comcast.net>

?? There are no device drivers included with RT11 for anything that I
recognize as a synchronous interface, so I would assume it only
supported a
standard asynchronous serial port.
That don't necessarily mean much. With RSX, DECnet has its own
device drivers.
