Indeed we seem to have a communication problem. From what you have written in 
your last mail, my proposal is different than what you're doing:

- You are always calling tcp_recved() when copying data to the buffer
- I propose to only call tcp_recved() for the amount of data that your buffer 
can hold.

Calling tcp_recved() gives the server permission to send more data, so you can 
use this to throttle the server. The server will never send more data than fits 
into the TCP window, so if you implement this correctly, you will *never* get 
more data than you can buffer. The only requirement here is that 
sizeof(your_buffer) >= TCP_WND.
