Chapter 10 – V.24-V.25
Refer to ITU-T Recommendation V.25 specifications if you desire more details about the following commands.

Fixed DTE Rate +IPR

This command is used to specify the baud rate for the module DATA port. The factory default value is
Description:
115200. When autobaud is specified (AT+IPR=0), the module sets the DATA port operating baud rate to the
detected DTE baud rate. The AT&F command restores the baud rate value that was active when the last
AT&W command was used.
The use of baud rates below 9600 may affect the operability of some module software features; e.g.,

Note: List of supported <rate> values,[(list of
fixed-only <rate> values)]
AT+IPR=38400
Note: Disable autobaud and set rate to 38400 bps
AT+IPR=0
(*) The first list of values are the baud rates that are detectable by the module autobaud feature. The second
list of values are the module DATA port supported baud rates

DTE-DCE Character Framing +ICF

This command is used to specify the UART start-stop (asynchronous) character framing for the module
Description:
DATA port. The factory default value is 3,3. The AT&F command restores the value that was active when
the last AT&W command was used.
