Pauly,
Ive just seen your other post on the same subject.

This could have clues to the problem.
Maybe Asynclabs can comment on the possible timing issues with the cli() command in wiring.c
While this may not be the solution it could provide some clues.
If I get some time later Ill have another play.
Id like to get this working as I want to use these together myself now.
