AT+CBAUD?
+CBAUD: 57600
OK
AT+CBAUD=?
+CBAUD: (0-13,300,600,1200,2400,4800,9600,19200,38400,57600,115200,230400,460800)

+IPR, Local Terminal/G24-L Serial Port Rate
This command is responsible for setting and saving the request baud rate. This numeric
extended-format parameter specifies the data rate at which the G24-L accepts commands.
Specifying a value of 9 disables the function and allows operation only at rates automatically
detectable by the G24-L. The specified rate takes effect following the issuing of any result
code(s) associated with the current command line.
The <rate> value specified is the rate in bits per second at which the terminal-G24-L interface
operates, for example, 19200 or 115200. The rates supported by the G24-L are
manufacturer-specific. However, the +IPR parameter permits setting any rate supported by the
G24-L during online operation.
The UART is configured to rates of 300, 600, 1200, 4800, 9600, 19200, 38400, 57600, 115200,
230400, 460800 bits per second according to the parameters of the +IPR command.
Using AT+IPR=<rate> with a <rate> value other than 9 and 0 disables the auto baud rate
detection feature. The entered baud rate is stored in the G24-L and is restored after power up.
Notes:+IPR is similar to +CBAUD, but with the ability to save.
