Hi Ralph, times ago, you have added the function to power off the NXT by pressing the orange button... But: what about implementing a function to break every running code and return back to interpreter ? It is very useful for debugging and (...) (17 years ago, 19-May-07, to lugnet.robotics.nxt)

(...) Hi there, Thanks for venturing those reasons. I had been thinking that with the release of the NXT firmware that there may be options to compile code that worked directly with the firmware. Cheers (17 years ago, 19-May-07, to lugnet.robotics.nxt.nxthacking)
