[comp.unix.ultrix] Are host-to-host LAT connections via /dev/ possible?

D. Allen [CGL]" <idallen@watcgl.waterloo.edu> (07/13/90)

Is there some way I can use "lcp -h" to point a LAT terminal in /dev/
at another LAT terminal in /dev/ on another machine, instead of pointing
it at a LAT terminal server port?  I'm not sure why I'd want to do this,
but I can't think why it shouldn't work.

I can.  ULTRIX is only a slave implementation of LAT.  A LAT system that
responds to host initiated connections is a master implementation.

In summary, you can't do it.

Well, it wasn't this sort of application that I was thinking of when I
designed this mechanism, but generality has its bonuses... For the
next release of cisco Protocol Translators (V8.2), if you have LAT
support, you could create LAT services which automatically issued a
LAT command to connect you to another host. You would set up the
LAT terminal in lcp just as if it was a printer service, and set up
the cisco to speak the master side of the connection to both Ultrix
systems.

This feature was designed to allow one to set up LAT services which will
connect to other systems via TELNET or X.25, but you could do LAT to LAT
as well.
