Making screen look for a pattern to detect "activity"

[Hari Bhaskaran]

Hi,

I want to make screen look for a certain configurable pattern in the 
output to detect "activity" (for the montoring feature
Cntrl-a M thingy). I am running a custom program which would print a 
certain pattern that I want to watch for, not
necessarily a strict "silence" or "activity"- which currently means any 
output.

Is there a way to achieve this in screen? Any help is appreciated
