SARA-R4/N4 series - AT Commands ManualUBX-17003787 - R09 B Appendix: AT Commands ListPage 292 of 307B.1 Parameters stored in profilesThe parameter settings of some commands can be stored in the profiles available in the memory module.SARA-R4 / SARA-N4To partially display these profiles, see the AT&V command description. Not all the parameter setting aredisplayed through AT&V command.Some AT commands have a unique configuration for all the AT interfaces while for other AT commands itis possible to set a different configuration for each AT interface: the "AT interface configuration sharing"column in the next table provides this information.Some AT command interfaces have a dynamic activation, which means they are not statically activatedat boot time (MUX AT channel is activated when the MUX protocol is established, USB AT channel isactivated if/when the USB cable is plugged-in, deactivated when it is removed). Since the activationreloads the AT command profile from NVM for the activated interface, the shared "AT interfaceconfigurations" could be overwritten. It is suggested to reconfigure them at the requested value if an ATcommand interface is dynamically activated.The following table lists the AT commands which setting can be stored in the profiles with their parametersas well as the factory-programmed values.AT command Description AT interfaceconfigurationsharingFactory-programmed value / Remarks&C DCD status No 1 (DCD enabled)&D DTR status No 1 (DTR enabled)&K Flow control status No 3 (RTS/CTS DTE flow control enabled)&S DSR override No 1 (DSR line set to ON in data mode and to OFF in commandmode)+CMGF Preferred messageformatYes 0 (format of messages in PDU mode)+CNMI New messageindicationYes • 1 (discard indication and reject new received message URCswhen MT-DTE link is reserved)• 0 (no SMS-DELIVER indications are routed to the TE)• 0 (no CBM indications to the DTE)• 0 (no SMS-STATUS-REPORTs are routed to the DTE)• 0 (MT buffer of URCs defined within this command isflushed to the DTE when >mode< 1...3 is entered)+COPS Operator selection Yes • 0 (autoregistration enabled)• 0 (operator expressed in long alphanumeric format)• FFFF (undefined PLMN to register when COPS=1)+ICF DTE-DCE characterframingNo • SARA-R4 / SARA-N4 - 3, 1 (framing format: 8 data 1 stop, noparity)+IFC DTE-DCE local flowcontrolNo 2 ( on circuit 106 (CTS)), 2 ( oncircuit 105 (RTS))+IPR Baud rate No • SARA-R4 / SARA-N4 - 115200 (115200 b/s)+UPSV Power Saving (mode,timeout)Yes 0 (power saving disabled)E Echo status No 1 (echo enabled)Q Result codesuppressionNo 0 (DCE transmits result codes)S0 Automatic answer No 0 (automatic answering disabled)S2 Escape characterselectionNo 43 (043 corresponds the '+' character)S3 Command lineterminationcharacterNo 13 (0x0d corresponds to the carriage return character)S4 Responseformatting characterNo 10 (0x0a corresponds to the line feed character)S5 Command lineediting characterNo 8 (008 corresponds to the backspace character)S7 Connectioncompletion timeoutNo 60
