0 - off

1 - standby, basically the same as off for the C++ code (3D instrument would power up the display, presumably)

2 - test, again the C++ largely ignores this since the test configuration of real-world instruments varies. In particular the unit does *not* for altitude or transmitted-id to any test values, you should do that in your own logic. (Maybe we should allow the test values to be defined int he config section?)

3 - Ground mode, responds to altitude interrogation but does not broadcast an ID. This would typically be used while taxiing prior to takeoff.

4 - On, normal operation but altitude transmission is inhibited

5 - Alt, same as on but altitude is broadcast if transponder was configured in Mode-S or Mode-C
