Hi Jon,
Finally I had the time to test your development. It is excellent! A friend of mine told me he had a problem when using IP comm in a sub activity .. I have to test this myself. It makes debugging finally possible for IP. This is great as I just found out that any comm with an extender must be with a real extender (even if I am not interested in the actual data from the extender). The simulator creates an error (when making a call to an extender) and ignores any additional code...
But you made it possible to check IP communication which makes this an EXCELLENT addition to PEP! Hopefully the guys at Philips get this info to and will improve debugging for the Pronto (which is very very basic..).. and maybe even development on a Apple ;-) (as I still have to use MS ... in an emulator ...:-)))).

Best regards
