Temporarily Store SMS Messages
If short messages are stored to non-volatile memory on the module, the +CMTI unsolicited response reports the
receipt and storage of the message. The +CMGL, +CMGR and +CMGD commands can be used to list, read and
delete the stored messages. For example:

The modem provides a comprehensive set of AT commands that allow the application to use TCP/IP for
data communications with a remote application. UART1 is time-multiplexed between on-line command
mode and on-line data mode, allowing the single serial channel to carry both AT commands and
application data. When using the CMUX interface, a dedicated virtual channel is used for data. The
device allows both TCP and UDP connections.
In this example, a TCP connection is established with a remote echo server application.
