[screen-devel] Re: Making screen look for a pattern to detect "activity"

[Hari Bhaskaran]

Thanks for the suggestion. However it would have been nice if screen 
could do this.
I would then be able to monitor commands I hadn't anticipated the need for
monitoring when I started the command.

If I were to try to patch such a thing on to screen, where should I 
start? I can see
screen.c 's  serv_select_fn() to be one place where I would probably 
look for the pattern
and then set from p->w_monitor ?

Any pointers/helpful hints are much appreciated.
