You have managed to get the LAT CommToolBox tool to work with MacX? I
am VERY SURPRISED, since they don't work together at ALL for the
purpose of X11 communications transport to the best of my knowledge
(and I had a LOT to do with the engineering of MacX).

However, to answer your question about LAT on A/UX, it's trying to do
things to the Ethernet driver directly and it CAN'T on A/UX.  Hence the
error.  I have no idea if there are plans to fix this (anyone else care
to comment?)...

Would you please email me details of WHAT you've got working on MacOS
with regard to MacX and the LAT tool?  Perhaps you've discovered
something I didn't know could work (I'm skeptical).

To explain:  DEC has used the LAT (LocalAreaTerminal) protocol, which
is a non-routed Ethernet direct protocol, as a communications transport
for their terminal servers (connection N serial terminals and other
devices to a box which then funnels them to various DEC hosts over
Ethernet).  They introduced LAT for X11 terminals about 18 months ago. 
BUT, the LAT they use for their X11 transport requires an extension to
the LAT protocol they use for their "dumb" terminal servers.  To the
best of my knowledge (and I DID ask -- several times) Apple does NOT
have the specifications for these extensions and our LAT tool does NOT
implement them.  Hence my skepticism.

I would LOVE to hear that I am wrong about this, though (pretty
please?).  --
