Chapter 8 – Communication
This command is used to specify the baud rate for the modem DATA port. The factory default
value is 115200.
Note:
At power-up, the interface rate is set to the value that was active when the last AT&W command
was used.
Note:
e.g., TCP App.
Command syntax: AT+IPR
This command is used to specify the UART flow control method. The factory default value is 2,2.
AT&F and AT&W are in effect. Software flow control is not supported.

Auto-baud (automatic detection of DTE rate) is not supported.
The use of baud rates below 9600 may affect the operability of some software features;
Commands
Transmit data flow control disabled.
Not Supported. Remove Xon (0x19) and Xoff (0x17) characters from data
stream.
