Any way to tell if read screen content timed out?

[Ouitoo]

The entire question is really contained in the subject line. Is there any good way to tell if a read screen content action times out? The actions that I perform on the screen content depend on having the current screen content.

Thank you in advance.

There is a system log trigger but I think you have to make a separate macro as macros can't trigger on their own log.
