You can't mix fopen and write() calls. fopen belongs with fwrite, open belongs with write.

Your first code wasn't wrong, either. It looks like it should write one more byte onto the end of the file.

I think what's wrong is the fact that you're writing single bytes. Are you sure your packets are single bytes? That seems really odd! You might be throwing out 99% of the packet.
