I also guess “*” means all responses and it should be documented. ADL is throwing many black and white boxes to OAT app developers. It would be nice adding a global event hook, similar to Window32 WinProc. OAT is not a embedded real time operating system. It is impossiable for OAT to catch all events/responses. For example, Q26xx/ex, OAT suppresses part of ARM946 power and is hardly to use in real-time system from my posonal point of view.
