Sets or returns the reference oscillator tuning voltage adjustment by sending a
DAC value in the form xxx, where:
xxx=is a numeric value from 0 to 255.
Default value: 087
NOTE: This command sets the DAC value, but the actual Reference Oscillator
tuning voltage can be monitored using the RMS command.
