2.3. Description of URCs

The URC of TCP/IP AT commands will be reported to the host in the format of beginning with +QIURC:. It
contains the reports about incoming data, connection closed and incoming connection and so on. Actually,
there is <CR><LF> both before and after the URC, but <CR><LF> is not presented intentionally.

2.3.1. +QIURC: "closed" Indicate Connection Closed

When TCP socket service is closed by a remote peer or due to network error, the URC will be outputted,
and the status of socket service will be "Closing" (<socket_state>=4). AT+QICLOSE=<connectID> can
be used to change <socket_state> to "Initial".
+QIURC: "closed" Indicate Connection Closed
+QIURC: "closed",<connectID>
Parameter
<connectID>

2.3.2. +QIURC: "recv" Indicate Incoming Data

In buffer access mode or direct push mode, after receiving data, the module will report URC to the host.
In buffer access mode, after receiving data, the module will report URC +QIURC: "recv",<connectID> to
notify the host. Then the host can retrieve data via AT+QIRD. Please note that if the buffer is not empty,
and the module receives data again, it will not report a new URC until all the received data has been
retrieved via AT+QIRD from buffer.
