I can't understand why people won't consider that TMCC is different than DCC and requires a different configuration.
We understand that TMCC is different to DCC. What you don't understand is that the differences between the various hardware systems is dealt with in the underlying abstraction layer of JMRI.
I don't need to try anything. You have the necessary information to change the abstraction layer to handle TMCC-2. I have no interest in doing anything about TMCC-2 as I am unlikely to ever have such a system in my sights let alone use it.
