Adjusts the reference oscillator tuning voltage by
sending a DAC value in the following format: REF=xxx,
where: xxx is a numeric value from 0 to 255, and the
default value is set to 87.
Example: <1/REF=087'cr'
>0001/REF='cr''lf'
Note: This command sets the DAC value, but the
actual Reference Oscillator tuning voltage can be
monitored using the RMS command.
Default Value: 087
