3.1. AT&C Set DCD Function Mode - page 31
The command controls the behavior of the UE‟s DCD (data carrier detection) line.
3.2. AT&D Set DTR Function Mode - page 31
The commanddetermines how the UE responds if DTR line is changed from lowto highlevelduring data mode.
3.3. AT+IFC Set TE-TA Local Data Flow Control - page 32
The command determines the flow control behavior of the serial port.
3.4. AT+IFC Set TE-TA Local Data Flow Control - page 33
The command determines the serial interface character framing format and parity received by TA from TE.
3.5.AT+IPR Set TE-TA Fixed Local Rate - page 34
The commandis used to query and set the baud rate of the UART. The default baud rate value (<rate>) is 115200bps. The setting of <rate>will not be restored with AT&F.
3.6.AT+QRIR Restore RI Behaviorto Inactive - page 35
If the RI (ring indicator) behavior is "always",it can be restored to inactive by the Execution Command. The RI behavior is controlled by AT+QCFG. Please refer to AT+QCFG="urc/ri/ring", AT+QCFG="urc/ri/sms incoming"and AT+QCFG="urc/ri/other"for more details.
