$MBn Modem Baud Rate
75, 300, 1200, 2400, 4800, 9600, 14400, 19200, 28800, 33600
33600
Presets the transmission baud rate for originate operations (i.e., the speed of the modem's
transmissions over the telephone lines when originating a call). With speed conversion,
transmission speed can be a different baud rate than the serial port speed.
When the modem receives a call from another modem, it automatically switches its phone
line transmission speed to match the calling mode. However, if the MultiModem originates a
call to another modem that is unable to connect at the MultiModem's baud rate, it
automatically drops to the lower baud rate in an attempt to match that modem's speed. For
example, if the MultiModem is set for 19200 baud and calls a modem with a top speed of
2400 baud, it drops to 2400 baud.
AT$MB75 = V.23

AT$MB33600 = 33600 bps
$RP Response Priority
n = 0, 1
1
Configures whether an incoming ring or an AT command will have priority.
$RP0 - AT command will have priority
$RP1 - Incoming call (ring) will have priority
