Hi Everyone,
When this command (at+cfun=1,1) is executed on phone, it does a reboot. I want to know which and how this command calls the kernel level functions. I googled this, but seems like all the data explains only about AT command and not as to how this reboot process is done.
The kernel alone is not responsible of interpreting Hayes commands (AT). According to ETSI TS 100 916 V7.4.0 (1999-11) Technical Specification Digital cellular telecommunications system (Phase 2+); AT command set for GSM Mobile Equipment (ME) (GSM 07.07 version 7.4.0 Release 1998), Section 8.2 Set phone functionality +CFUN (found through by http://wiki.openmoko.org/wiki/Hardware:AT_Commands ), this command (AT+CFUN=1,1) is one of the command a "baseband" must implement. And this command is asking for a reboot. So what you describe seems more likely to be a hardware problem. Regards. -- Yann Droneaud OPTEYA
