We don't need any complex negotiation at the link setup.
We can even do it dynamically depending on the memory available
in the stack for example. The only drawback of our scheme
is that it can't transmit a "list" of outstanding frames,
only one at a time. But TAPR's scheme can't do that either.

It's much more complex than our scheme and has as far as
I understood no benefit.

I agree that the Flexnet _internode_protocol_ is a lot less well
documented than it could be (however there's a relatively old
interradio proceeding which documents the protocol elements,
and there are alternative implementations as well).

So do it, if you think it's worth doing, then we can
judge the real world behaviour...

No why? Most compression specs just define the _decoder_. So why
shouldn't
we just specify what is to be seen on the air and leave the "how" to
achieve this to the implementors? (you could add an appendix with
suggestions
though.)

Yes it is. The majority of TNC's sold by all the commercial companies
and TAPR has still in the range of 32k

Not everyone uses Linux. Another thing is installed base. You just won't
manage to obsolete all the installed base at one day just for
the sake of a new protocol.

That's fine if you are happy with 1200 bauds. I'm not. And no, telecomm
protocols aren't moving towards unnecessary complexity, on the contrary.

The experience I had in the latest project was a bit different.

But that is complete nonsense! If you want to establish a new protocol,
you can't just live in an ivory tower and ignore all installed
equipment!

Ok, fine, I won't follow it :-)
