title: How to send one byte symbol to server socket with netcat?
body: <p>There's already a working server service via socket, and I would like to test it via netcat. I'm using Mac OS X Lion. Currently, I'm able to connect to server via port, to send packet, but the packet contains wrong value. Here are the details:</p>
  
  <p>I need to send 'm' symbol to the server and the server will return 00000000, a zero byte as a response. Server guy told me, server receives 'A0' when I'm sending 'm', and server receives '313039A' when I'm sending '109'. How to define sending format or something, I just need to send 'm' (01101101)? </p>
