G.6.4.5.1.3 Demodulator/Decoder Configuration Status
The Demodulator/Decoder configuration status command causes a block of data to be
returned by the addressed modem. The block of data reflects the current configuration of the
demod.
Command: <add/DCS_”cr”
Response: >add/DCS_”cr”
DF_nnn.nnnn”cr” Demodulator frequency
