You should start another thread, it's a different problem.

What protocol are you using? If you are using UDP, then it isn't guaranteed that the packet will be delivered. To control and configure it is better to use TCP, so that you are sure the data is sent and received. You may have to use an additional function call on the sending side to force the 4 bytes to be sent immediately and not kept in a buffer though.
