+MRR: m,n
Report Syntax
Response: +MRR: m,n
m Decimal transmit rate in bits/s.
n Decimal receive rate in bits/s.
Example: MRR: 28800, 48000
10.4.24 +MS - Select Modulation
This extended-format compound parameter controls the manner of operation of the modulation
capabilities in the modem. It accepts six subparameters:
Command
+MS=[<carrier>[,<automode>[,<min_tx_rate>[,<max_tx_rate>[,<min_rx_rate>[,<max_rx_rate>]]]]
]]
Where: Possible <carrier>, <min_tx_rate>, <max_tx_rate>, <min_rx_rate>, and <max_rx_rate
values are listed in the following table. (see definitions below).
