3.4.2 UART Serial Communication
SIM8200G provides a full-featured serial port. By default, when used as an ordinary serial port, we can set the data frame format of the serial port and set the baud rate and other operations.
1) Set the serial data frame format
SIM8200G supports multiple serial data frame formats. The default data frame format is 8 data bits, 1 stop bit, and no parity bit.

If you need to modify the data frame format, please refer to the instruction AT + ICF. Common data frame format settings are as follows ：
Table 9: UART common data frame format settings

AT+ICF=1,0
AT+ICF=1,1
AT+ICF=4 、 AT+ICF=4,2
AT+ICF=3,0
AT+ICF=3,1
2) Set the serial port baud rate
SIM8200G supports a variety of common baud rates. The standard factory default baud rate is 115200, and it supports automatic baud rate adaptation. There are two methods to modify the baud rate. For temporary modification and long-term modification, please refer to the instruction AT + IPR for temporary modification. Please refer to AT + IPREX for long-term modification of the baud rate. The serial port baud rate is modified for a long time, and the baud rate will be saved locally, so it will continue to take effect after the next boot. The temporary modification of the serial port baud rate will be invalidated after restart. The baud rate will be restored to the locally saved baud rate.
Table 10: UART baud rate support
UART baud rate support Supported rate
Serial communication baud rate 300,600,1200,2400,4800,9600,19200,38400,57600,115200,
230400,460800,921600
Serial port adaptive baud rate 9600,19200,38400,57600,115200
2) Common baud rate instructions for serial ports ：

3) Set serial data flow control The serial port of SIM8200G adopts RTS / CTS flow control mode, but the www.simcom.com
24 / 26
SIM8200G-EVB_User Guidelines_V1.01
full-featured serial port of SIM8200G works by common serial mode by default. If we need to set the working mode of serial flow control, please refer to AT + IFC.
Serial flow control configuration instruction setting method ：

Setting instructions
AT+IFC 、 AT+IFC=0,0
AT+IFC=2,2
AT+IFC=2,0
AT+IFC=0,2
The method of using serial port RTS flow control can be verified by using the serial port tool. When RTS flow control is set, if RTS is not checked, it means that RTS does not take effect. At this time, two consecutive ATs are sent. It is found that the window of the serial port tool does not show AT and return value.
Figure 22 serial port tool without AT and return value
Then check RTS to make RTS take effect, and then the window of serial tool will display AT and return value.
