Whoa!  Does this mean that source for A/UX is available?  Where did you
get the tc driver source?  Is this available, and if so, how much does it
cost?

A related question.  I would like to replace the SLIP driver in the A/UX
kernel by the new beta test version from Van Jacobson which does header
compression and priority queueing of interactive packets.  Has anyone done
this yet?  Any chance that Apple plans to do this, e.g., for A/UX 2.0?
If I have no other options I may attempt it, but it could be difficult
without kernel source, particularly source for the current SLIP driver
in A/UX.
