O.C. Radios: how to utilise F.O tuning radios ?

Does anyone know if it is possible to get Open Cockpit Radios to change frequency by using some of the 3rd party Air Traffic Control and or First Officer programs ?

I have tried and it will momentarily changes frequency but then changes back on the read-out, even though the voice comes through as it appears to stay on the correct frequency.

So not sure where to look for an answer, as O.C. never seems to reply.

OK...............Found the answer and it is in the programming of SIOC.
