Jason's "patch" is actually playing ethernet for you. So, even without any separate machine with the bridge program on, or even without a real ethernet port on your machine, your simh can have a simulated ethernet, which hooks into my bridge program, making the simh machine appear to be on the virtual ethernet segment created by the bridge program.

I have two systems nominally connected to HECnet, both emulated. I have
the SIMH VAX emulator running VMS (DUSTY) and I have Mark Crispin's
Panda system running TOPS-20 (CALHAN). Both of these are running as part
of virtual Unix systems (one Linux, one Solaris) on a single ESXi box.
I've also played with a couple Alpha emulators from Stromasys
(CHARON-AXP on Windows and CHARON-AXP NCE on Linux), but I've not set up
a more permanent virtual Alpha system.
I'd set up a virtual PDP-11 to play with as well, perhaps running
RSTS/E, but it's been far too long since I've used a PDP-11 to remember
how to set it up and maintain it. Same thing with VM/370 or z/VM on
Hercules. It's sad how much I've forgotten over the years.

Unfortunately, given my preference to using RSTS/E v8, I must use
DECnet/E v2.0. Those DECnet drivers only support a DMC or DMR device
(seen as "XM" in RSTS), or a DMP or DMV device (seen as "XD" in RSTS).
Based on what you're saying, the patch would not solve this problem?

Yes.
Or rather, the terminal driver contains an implementation of the DDCMP
protocol. So it can talk to async DDCMP devices -- just as RSX did
for years. Until V10, DECnet/E only did DMC/DMR type DDCMP devices.
On a Pro, which has a USART (not UART) console port, it even speaks
sync DDCMP if you want so it can talk to a DMC or DMR (and that works,
I tested it). On other PDP-11s it will use any of the async lines and
speak async DDCMP.

Sorry to report, but DECnet/E on RSTS/E v8 has no support for networking
over such devices. Else I would've done this years ago. Remember *v8*.
Not 9, and not Mentec. :)

Huh? What do you mean simh don't support any DDCMP-aware devices. You do
know that DDCMP can be run over asyncronous serial lines do you?
This means as long as you can emulate something like a DL11, DZ11, DH11,
or any other stupid serial port, you'll be able to play DDCMP.
Atleast if you are running RSX. Because the next question is what your
OS on your simulated machine can talk DDCMP over, which is a relevant
question here. :-)

Yeah, if I didn't think that every version of RSTS after v8 is a total
abomination. :) I run v8 on purpose, because I actually used to use it
back in the 80's. It's the last "pure" version, before DEC turned it
into crap to make VMS people happy.

That should actually be pretty simple. Much more simple than any other kind of networking. Anyone should pretty much be able to hack that one together as long as they know just a little about programming for sockets, and have a basic understanding of ethernet.
No strange things needs to be done in relationship with any OS.
