Unit returns the value of the measured frequency offset of the
carrier being demodulated, in the form sxxx.x, where:
xxx.x=value (range from 0 to 200 kHz, 100 Hz resolution)
Returns +999.9 if the demodulator is unlocked
Example: RFO=+002.3 (2.3 kHz)

Unit returns the value of the buffer fill state, between 1 to 99%
Returns 00 if demodulator is unlocked
Example: BFS=33 (33%)
