command and TCP settings by AT+IPTCP command
- ONLY GPRS PDP context # 1 will be used. So please setup +IPGPRS settings with
<cid>=1
- Once AutoTCP is enabled, it will start the TCP socket connection automatically after 20
seconds.
- Once the TCP connection is established successfully, the serial port will go to data mode,
all data entered to the serial port will be sent to remote TCP peer. No more AT commands
will be accepted then.
- In TCP connected data mode, the DSR and DCD signals of the serial port will go to high.
