4.6AT+ICF Serial Interface Character Framing

The command AT+ICF controls the serial interface character framing format and parity used for receiving and transmitting.

The following settings are supported:

•7 bits, even parity, 1 stop bit (AT+ICF=5,1)

•7 bits, odd parity, 1 stop bit (AT+ICF=5,0)

•8 bits, even parity, 1 stop bit (AT+ICF=2,1)

•8 bits, no parity, 1 stop bit (AT+ICF=3)

•8 bits, odd parity, 1 stop bit (AT+ICF=2,0)

•8 bits, no parity, 2 stop bits (AT+ICF=1)
