Hardware Information
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 and is restored after power up. The
G24 supports up to 57600 auto baud.

+IPR is similar to +CBAUD, but with the ability to save.
ATZ command sets the G24 to default baud rate - Auto baud rate, and the saved baud rate
is restored only after power-up.
