3.2. AT Command Interface
In ATC mode, using the standard AT command and the ten
extended AT commands enables you to access the Internet. If the
connection is successful CONNECT message is displayed and if the
connection is failed or terminated NO CARRIER message is displayed,
which is similar to a standard modem. The modem commands
supported by ezTCP are listed below:

3.2.2. Extended AT Command
ezTCP provides the unique extended command for the control of the
Internet-related setup values, which are not supported by a standard
modem. The extended AT commands start with 'AT+P' and are
followed by the equal sign, '=', for setting up values. The question
mark, '?', should be added to the end of the command when
outputting the setup value. For example, enter the command when
changing or checking ezTCP's IP address as follows:
AT+PLIP=a.b.c.d
>>
<< OK
AT+PLIP?
>>
<< a.b.c.d
The extended commands available on ATC mode are listed below:
