Response:
>add/DR_nnnnn_mmm.mmmmmm'cr''lf']
Where
nnnnn = 1/2 (QPSK 1/2) [Decoder rate], 3/4
(QPSK 3/4), 7/8 (QPSK 7/8) , 5/6 (QPSK
5/6), 2/3 (QPSK 2/3), 8P23 (8PSK 2/3),
8P56 (8PSK 5/6), 8P89 (8PSK 8/9),
16QAM34 (16QAM3/4), 16QAM78
(16QAM7/8).
mmm.mmmmmm = Data rate in MHz.
Note: When using a SMPTE 310M interface,
the data rate is fixed at 19.392658 MHz. While
the code rate can be changed as applicable, an
invalid parameter message will be generated if
any other data rate is input for change.

The demodulator configuration status command
causes a block of data to be returned by the
addressed demodulator. This block of data
reflects the current configuration status of the
demodulator module. Additional configuration
status of new options and features will always
be appended to the end.
