Serial Interface Control Commands

AT&C Set DCD Function Mode


The command controls the behavior of the UE‟s DCD (data carrier detection) line.

AT&D Set DTR Function Mode


The commanddetermines how the UE responds if DTR line is changed from lowto highlevelduring data mode.

AT+IFC Set TE-TA Local Data Flow Control


The command determines the flow control behavior of the serial port.

AT+IFC Set TE-TA Local Data Flow Control


The command determines the serial interface character framing format and parity received by TA from TE.

AT+IPR Set TE-TA Fixed Local Rate


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.

AT+QRIR Restore RI Behaviorto Inactive


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.
