Command Action
Notes:
1. When in autobaud mode, \B0, \B1, and \P1 will not be detected automatically. The combination of \B2 and \P3 will be
detected. This is compatible with seven data bits, no parity, two stop bits. Seven data bits, no parity, one stop bit may be
forced by sending AT\T17\B1.
2. The autobaud feature does not detect this rate.
3. Default is \T9 if a pulldown resistor is connected to the autobaud strap pin; otherwise, the default is \T16.
