DualModeController now distinguishes between
- supported commands: commands enabled in the supported commands mask
- implemented commands: commands for which an implementation is provided

- supported but not implemented command: raise an assert
- unsupported commands: send command complete which ERR_UNKNOWN_COMMAND
