You've probably noticed that I'm not very familiar with RT-11; my operating
system "home" is VMS.
I've got three more questions, two for SIMH (but related to DECnet-RT) and
one for RT-11 / DECnet-RT.
- I am familiar with connecting two SIMH VAX instances for asynchronous
serial DDCMP, which looks like:
VAX A:
SET DZ ENABLE
SET DZ LINES=4
ATT DZ LINE=0,44012,CONNECT=127.0.0.1:44021
VAX B:
SET DZ ENABLE
SET DZ LINES=4
ATT DZ LINE=0,44021,CONNECT=127.0.0.1:44012
The first question is how to configure a SIMH PDP-11 running DECnet-RT and
a SIMH VAX running DECnet-VAX over asynchronous serial DDCMP.
The second question is how to configure two SIMH PDP-11s running DECnet-RT
over asynchronous serial DDCMP.
The third question is can I start e.g. FAL and continue interactive work,
e.g. using RVT?
I hope I'm not being too pushy - Thanks a lot for your valuable continuous
help!

RSTS, I assume. And PyDECnet has a LSN also.

The following servers are available:
NML - Network Management Listener (use with NCP)
FAL - File Access Listener (use with NFT)
LOOPER - Loop testing (use with NCP LOOP NODE name)
So there is TLK but not the matching server (LSN)? It should talk to
paul
According to the object definitions, it looks like TLK is both client and
server.
