Exactly! thats what I meant with my response.. there seems to be a 'complete' misunderstanding!! the fact that SB4 uses SimConnect doesn't have ANYTHING to do with the fact that FSUIPC can still be used to trigger transponder modes the same way PTT works today...
My concern is that the guy who replied in that thread is Norman!! Well Known SB tester, VATSIM VP, Close to the SB developers!!! it would be fantastic if you jump in that thread and 'clarify' this for him.. I'm PRETTY sure he will raise this issue with Joel ASAP.
No misunderstanding at all. I personally use both Simconnect and FSUIPC for what I need. On an aside, whilst I dont expect a prompt answer, I'll nudge Joel once again.
