I don't see how what you are describing could possibly work.

The diagram functions Handle Poke and Handle Peek are used to store and
retrieve data in a "Handle",
which is a block allocated using Size Handle. They are not general "memory
write/read"
functions. You cannot wire up a numeric address to the Handle Poke or
Handle Peek function.
As such, I am not sure how you could have wired up an address of C000 and
had it work.
I would strongly suggest looking at your code, because I doubt that it
works correctly.

We frequently hear questions from customers mistakenly thinking of them as
"Memory Poke"
or "Memory Peek" functions. Because of the confusion they cause, and
because they don't
really add any significant functionality, we've decided to remove them from
LabVIEW in
the next release.

(CIN Users: note, we are not removing the CIN handle functions -- we are
removing the three
handle functions that are present in the MISC palette.)

Please contact me if you are currently using any of the handle functions.
