Hi all,
Quick question: is there currently a way to see how many slot are
used in the FSM (i.e. how many free pages are stored there), or how
many are free? If not, wouldn't it be a good idea to add this
somewhere? (Don't quite know where... is it possible to have very
dynamic values in show xxx?) This would help a lot finding out
whether the current fsm settings are fine or not...
Thanks,
Jacques.
