The z21 has distinct Main and Programming (service mode) outputs, which for the most part work as expected.
However, using DecoderPro's throttle, I can operate lights and even get the loco to move while on the programming track. Is this expected service mode behaviour, or does it indicate that the Programming track is a hybrid service mode / main track capable of sending both service mode and run commands?
