Yes and no. I implemented PRO support for RSTS in 9.6, and ported it to 10.1. The INIT
part of that was merged with the official sources and exists in V10.1 (I forgot if it is

I would like at some point to make that available. One possibility, which I packaged up
some years ago, is a set of 3 floppies which replace the first two of the 10-disk
MicroRSTS kit (called V1.0, which is a V9.6 repackaging). The DECnet part needs some more
cleanup, though. And I don't yet have CNA (PRO Ethernet) support).
I wrote NODVR, the software DDCMP driver, as part of that V9.6 effort. The RSTS team
decided to merge that as well, but they changed how it is controlled in V10 -- for the
better. And that is entirely independent of the PRO work, it operates with any serial
line. Well, on the PRO there is an additional item: it can run the comm port in
synchronous mode, which lets you talk to a DMC or the like if you have a synchronous modem
or sync modem eliminator.

I thought that I had sent a message to the list a few months ago showing the procedure to
use the software DDCMP driver in RSTS V10.1. That's a standard feature, but
undocumented and probably unsupported. It works well and interoperates with PyDECnet and
with the DDCMP implementation in SIMH. Presumably it will talk to the software DDCMP in
RSX, though I have not tried that.
Attached are the instructions and the program mentioned.
From the first line of async-rsts.txt:
=======
Software DDCMP in RSTS/E V10
NODVR, a software DDCMP driver was written for V9.6 as part of PRO
support (an unreleased and unsanctioned effort).

Does this mean that there is support for running RSTS on a PRO desktop? Time to rummage
through the source...
