Note that if you apply this to your local clone, you will have to delete any file that is updated by Oscar/Angelo later. I believe they are going to eventually integrate these changes.

Updated with the latest, custom IOTs can now signal a break to the sequence break system, see the example in the IOTs directory.

A note, the 16 channel break system is not enabled in the emulator, nor is there any way to do so. Not sure why. I tried it, didn't seem to work properly but I haven't really looked into it.

The dynamic IOT add-in will support it.
