[HECnet] Hecnet and DDCMP

[Kevin Reynolds]

Rob,

If it is passing all bits from the serial port over, it should work.   My understanding is that serial was solely DDCMP, at least during the VMS days.

Reviewing the simh archives from 2005 I noticed a reference to ipcom (windows package for connecting a physical rs232 port to a network port, allowing serial login from a remote machine), but this won't work for me, as I need DDCMP, not a console connection, not to mention I'm hoping to physically connect a VMS system in the big picture, not simulations.   Perhaps there is some configuration to make this happen, I may test the windows/simh setup just to see.

Mark, the toolset will probably work for your purposes.

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?
