To demonstrate the writing of a setting, we write 2150000000 to the setting Frequency (setting 3) of
category Tuner and demodulator settings (category 0x90). The command below assumes that
configuration settings are available in

DtmCmd –w 0x90 3 2150000000
The parameters used in this command have the following meaning:
-i 0
Set the index to 0.
