Yes, both client and server are simulated on the same PC. I can Wireshark, but I don't want to spend the time to do that right now. Since I'm evaluating solutions for my application, I will try using Keba's K_Network library. It has tcp wrappers as well, but the data buffer handling must be coded, so it's a little more work. Since my last reply, I have a server up and running that I can telnet to and it seems robust, so for the moment I will continue in that direction.
