Required unsolicited responses for the IP stack versions 2.00 and 2.10:

- The IP stack requires certain responses for it to initialize correctly. If these respones are turned off during boot, it can cause the stack to not function properly.
- +CREG, +CGREG, and +WIND respones are required. The stack automatically enables these responeses during boot-up.
- The IP stack version 2.10 will not allow you to change the +CREG and +CGREG unsolicited response settings with‘AT+CREG=0’ and ‘AT+CGREG=0’. You will receive an "ERROR" response. An ‘AT&F’ will set the +CREG and +CGREG settings to default, causing the unsolicited responses to not show, which can cause the stack to not function properly.
