[HECnet] Hecnet and DDCMP

[Rob Jarratt]

Sorry for the delay in replying, I have been away. My friend was going to
announce it, but I can't remember if he did so. I will check with him. Note
that I have only tested it with versions 4 and 5 of VMS, so I cannot say if
it will work with RSTS/E.

Regards

Rob

Jarratt, did you make this publicly available on the SIMH list?   It would
be great
to have a DMC11 device emulated, since I insist on running RSTS/E v8 (for
historical reasons... it was the last real RSTS before "the pollution").
RSTS/E v8
doesn't have ethernet support, so the only way I could have DECnet is via
a
(previously unemulated)
DMC11 interface.   Does yours work well?

Working with a friend, I  have written a SIMH emulation of the DMC11
device, so you can do this with SIMH. It tunnels the bytes sent
to/from the device over a socket. We have used the SIMH emulation to
connect my friend to HECnet over a (simulated) DMC11.

The bit I am not entirely sure about is to what extent this is using
DDCMP as I don't have a full understanding of DDCMP.

Hey guys,

Has anyone worked out a mechanism to connect a node to hecnet using
DDCMP?
  Perhaps some tunneling technology over IP, or virtualized serial?
