We have a 65 user license that we are bumping up against.
Obviously, we could buy more licen$e$. We would prefer
to more effectively use what we have. Recently, I set
the ctimeout value to 90 for the session parameter of the
miscellaneous configurator. This works for terminals setting
at a colon prompt and inactive for the 90 minutes but it
does not work for a terminal setting idle with a menu displayed.
The other disadvantage is that it keeps logging off the operator
console.

Are there alternatives?

BTW we have limit 5,60.
