We regularly call a UV subroutine "ASKOK" which returns 'OK'. If it
doesn't, it is assumed the connection has broken.

From my tests, you are right about IsActive - it is the results of the
last connection (I think) and has nothing to do with the current state.
I added a timer function to our VB front end that runs every 60 seconds
and just opens a file. If the connection has been lost, the open is
unsuccessful. We display a message informing the user that the
connection is broken and they need to log on again.
This function has almost no overhead and keeps users from spending
several minutes or more on a form, then discovering that nothing was
saved. It also solved the timeout issue where people would go into a
meeting or out to lunch and their connection would be timed out for
inactivity. The function runs from only from 6am to 8pm, their local
time. If users go home at night without logging out, their connection
is still logged out for inactivity instead of being connected all night.
