Response:
<add/DF_nnn.nnnn'cr'
>add/DF_nnn.nnnn'cr''lf']
<add/DF_'cr'
>add/DF_nn.nnnn'cr''lf']
Where: nnn.nnnn = Frequency in MHz, 50.0000 to 180.0000,
in 2.5 kHz steps.

Response
Status:
Response:
<add/ADRx_nnnn_mmm.mmm'cr'
>add/ADRx_nnnn_mmm.mmm'cr''lf']
<add/ADRx_'cr'
>add/ADRx_nnnn_mmm.mmm'cr''lf']
Where:
x = A, B, C, D, or V (Preset designator).
nnnn = 1/2, 3/4, 7/8, or BP12 (Decoder rate).
mmm.mmm = Data rate in kHz.
Notes:
1. When ADPCM Interface is selected, only 32.000 and
64.000 are allowed.
2. When the Async Interface is used. If the ASYNC
baud rate is higher than allowable for the new data
rate, the maximum baud rate will be selected
automatically.
