What does telnet look like "on the wire"?

Pretty close to raw characters in IP packets. There's a little more to it, described in RFC's 854 and 855.

There's also RFC 2217, which describes how to use the telnet protocol itself to do things like line rate and hardware setup for just this application. And finally, I found this post to the TINI mailing list with just the code I'm looking for. Though ultimately I'd like to extend it to both ports and the 1-wire interfaces, it's a good starting point.

So now I need to get the hardware and start hacking.

Nice to know there's someone with some TINI experience out there, though.
