The TCP/IP stack ++parses the headers in the packet, and calls upon the application. If ++the remote host has sent data to the application, this data is present ++in the uip_buf and the application read the data from there. It is up ++to the application to put this data into a byte stream if needed. The ++application will not be fed with data that is out of sequence. ++ ++If the application whishes to send data to the peer, it should put its ++data into the uip_buf, 40 bytes from the start of the buffer.
