That would be nice for talking to real DECnet nodes. paul On Jun 22, 2012, at 2:31 PM, Rob Jarratt wrote: I am making a little progress on a user mode DECnet router that will run on Raspberry Pi and on Windows. There is still a long way to go, but I want to get the basic design right in terms on the network interfacing. Can someone tell me how Cisco and Multinet encapsulate DECnet packets sent over the internet? Thanks Rob Yes, that should be the simplest one. For that I am assuming that the router would be connected directly to the Ethernet segment, not missing anything am I? Regards Rob Right, that's what I had in mind. An Ethernet segment with a PDP11 on it along with your creation. Extra credit would be support of point to point links... which I could actually use, since my current PDP11 speaks DDCMP but not yet Ethernet (no driver for its NIC yet). That's off the wall enough that I wouldn't expect you to do it, but I would probably take it on as an additional feature. paul DDCMP over some kind of serial line? Would need appropriate hardware and driver code to work against that. Regards Rob
