2.2.8. AT+QIRD Retrieve the Received TCP/IP Data

In buffer access mode, after receiving data, the module will buffer it and report +QIURC:
"recv",<connectID>, then the data can be retrieved by 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 are retrieved via AT+QIRD from buffer.
