MC75i AT Command Set2.8 ATZ2.8 ATZ Set all current parameters to user defined profileATZ sets all current parameters to the user profile stored with AT&W. If a connection is in progress, it will be terminated.All defined GPRS contexts which are not activated or not online will be undefined if the non volatile storage ofCGDCONT settings is not activated by the AT^SCFG parameter "GPRS/PersistentContexts" (see AT+CGDCONT).The user defined profile is stored to the non-volatile memory.SyntaxExec CommandATZ[]Response(s)OKPIN ASC0 ASC1 USB MUX1 MUX2 MUX3 Charge Last Reference(s)- + + + + + + - + - V.250Parameter Description (num)[0] Reset to user profileNotes• First the profile will be set to factory default (see AT&F). If there is a valid user profile (stored with AT&W), thisprofile will be loaded afterwards.• Any additional commands on the same command line may be ignored. A delay of 300 ms is required beforenext command is sent, otherwise "OK" response may be corrupted.MC75i_ATC_V01.100 Page 40 of 548 11/10/08Confidential / Released

MC75i AT Command Set2.9 AT+CFUN2.9 AT+CFUN Set phone functionalityThe AT+CFUN command serves to control the functionality level of the ME. It can be used to reset the ME, tochoose one of the SLEEP modes or to return to full functionality.Intended for power saving, SLEEP mode reduces the functionality of the ME to a minimum and thus minimizesthe current consumption. Further information, particularly power supply ratings during the various operatingmodes and the timing of hardware signals in SLEEP mode can be found in the "MC75i Hardware InterfaceDescription, Version 01.100".SLEEP mode falls in two categories:• NON-CYCLIC SLEEP mode =0• and CYCLIC SLEEP modes, selectable as = 7 or 9.NON-CYCLIC SLEEP mode permanently blocks the serial interface. The benefit of the CYCLIC SLEEP mode isthat the serial interface remains accessible and that, in intermittent wake-up periods, characters can be sent orreceived without terminating the selected mode. This allows the ME to wake up for the duration of an event and,afterwards, to resume power saving. Please refer to Section 2.9.1, Wake up the ME from SLEEP mode for asummary of all SLEEP modes and the different ways of waking up the module.For CYCLIC SLEEP mode both the ME and the application must be configured to use hardware flow control.This is necessary since the CTS signal is set/reset every 0.9-2.7 seconds in order to indicate to the applicationwhen the UART is active. The default setting of hardware flow control is AT\Q0 which must be altered to AT\Q3.For use after restart you are advised to add it to the user profile saved with AT&W.If both interfaces ASC0 and ASC1 are connected, hardware flow control must be set in either application. Seenotes below for further detail.The AT+CFUN test command returns the values of the supported parameters.The AT+CFUN read command returns the current functionality value.The AT+CFUN write command can be used to reset the ME, to choose one of the SLEEP modes or to return tofull functionality.SyntaxTest CommandAT+CFUN=?Response(s)+CFUN: (list of supported s) , (list of supported s)OKRead CommandAT+CFUN?Response(s)+CFUN: OKWrite CommandAT+CFUN=[[, ]]Response(s)OKERROR+CME ERROR: PIN ASC0 ASC1 USB MUX1 MUX2 MUX3 Charge Last Reference(s)- + + + ± ± ± - + - GSM 07.07MC75i_ATC_V01.100 Page 41 of 548 11/10/08Confidential / Released
