The serial autobauding feature is supported for the following serial speeds only:
1200, 2400, 4800, 9600, 19200, 38400, 57600 115200, 230400, 460800, 921600 bps.
Beyond those serial speeds, proper operation of the modem is not guaranteed.
Any AT command issued by the DTE must start with both capital ‘A’ and ‘T’ (or ‘/’) or
The DTE waits for 1ms after receiving the last character of the AT response (which is
both lower case ‘a’ and ‘t’ (or ‘/’); otherwise, the DCE may return some garbage
characters and become desynchronized. Should this happen, the DTE simply issues
‘AT\r’ (at 2400 or 4800 bauds) once or twice or just ‘AT’ (at 9600 bauds) to
resynchronize the modem.
always ‘\n’ or 0x0A) to send a new AT command at either the same rate or a new rate.
Should this delay be ignored, the DCE can become desynchronized. Once again,
sending ’AT\r’ once or twice or just ‘AT’ causes the DCE to recover.
When starting up, if autobauding is enabled and no AT command has yet been
