- server.exe and client.exe do a simple exchange of messages (each sends one message to the other) and then terminate. - server_multi.exe and client_multi.exe exchange 3 message with one another before termination. - client_delayed.exe waits one second before sending any message to the server after a connection ahs been made (otherwise identical to client.exe) svn path=/branches/GSoC_2011/TcpIpDriver/; revision=52082
