stage for input channel 1.
S01MIC1x , where x is 0 or 1 depending
on the current enabled state of the
microphone gain stage on input channel

8.103. MINI -- Enable Modem Initialization String
This command controls whether or not the modem initialization string is sent at power-up. If MINI is
0, then the modem initialization string is not sent. If MINI is 1, then the modem initialization string is
sent. The text of the modem initialization string is set via the
MINISTR command.
This command is a boolean command. See
Section 6.1 for more information on this type of command.
This command is saved to global non-volatile memory and is not part of a preset. Its value is saved
each time it is changed. It will retain its value after power-down. Since this command writes to non-
volatile memory, there will be a delay before an acknowledgment is returned.
