I would think that the simulators have very little to do here, at least on the PDP11 end.
If a sync serial device is emulated as a stream of bytes, the rest is up to the software.
At least in the 2780 emulation case, where BISYNC protocol handling is in software and the
serial ports just are raw byte pipes.
Then it's a matter of finding RJ2780 software. I know it exists for RSTS, though
I've never used it. (It uses the KG11 to accelerate CRC processing, I'm not sure
if that's optional or required.) RJ2780 was a product family available with a number
of operating systems so I'd assume RSTS isn't the only OS that had it. Finding a
copy might be an interesting exercise -- that appears to be the road block Peter is
talking about.

Hercules does have 2703 emulation, and bisync emulation does seem to be
present in SimH. I think both support some level of TCP, so you might
be able to lash them up that way - but I would expect some hiccups along
the way. But that would indeed still leave the software question from
the original post. I am looking for the following software products
for a PDP-11, ideally to
be run on RSX-11M.
