[Hilo] difference between <AT+CFUN=1,1> and <AT+CPOF>

[Hilo] What’s difference of <AT+CFUN=1,1> and <AT+CPOF> in Hilo 3G?

Answer: <AT+CPOF> will switch off the whole module. But if PWON signal is grounded, module will be restarted again.
<AT+CFUN=1,1> will restart the module. When <AT+CFUN=1,1> is used, there will be a toggle on the external CTS and DSR pin in UART interface.
