Network Programming

Hmm, if you use TCP port 7 (Echo protocol) you will only receive what you transmit and is usually used for round trip time testing.  Is that what you want?  If you want to actually communicate with another computer, you will want to use a port greater than 8000 and actually greater than 10000 is even better, in order to avoid TCP/UDP standard ports and to a lesser extent port scanning attacks.
