TFTP Server not receiving from Client
===

I am developing a TFTP Server using C++. The problem is that I cannot receive or at least I do not see anything in the receiving buffer when I use a TFTP Client Demo (HS TFTP) which is available over the internet.

I can 'sense' that my app is receiving something, but I cannot see what was received when I use that demo for TFTP Client. 
So, what I did was to create a client myself and send a command like 'WRQ'. In this way I am able to receive the command which was sent. Thus I do not have an idea why I cannot see what is coming from a regular TFTP Client that can be found on the internet.
