IP over HF packet, was Re: [HECnet] Area 19

We'd probably use DDCMP to get it to the async level, right? Maybe. I know that AX.25 has a protocol ID byte that specifies the packet type being piggybacked - I'm pretty sure IP is 0xCC. It might be that someone has already implemented a DECnet payload, but it's a long shot. We could build our own TNCs that spoke 1200/9600 baud AX.25 on one side and DDCMP on the other. All it really takes is some firmware... That'd be a really cool gizmo, and completely useless to anyone except for a couple of people to boot :-) Realistically, a smarter thing might be to try WiFi. I think the current distance record for WiFi is something like 250 miles; how far is between you and Steve?? Of course, you'll need some pretty tall towers... Bob
