It's a system that let's you chat over Internet and LAN. It's a Java platform software so you can use it also in Machintosh and Linux system with a java virtual machine installed. It uses two Jar files: TCPServer.jar and TCPClient.jar. The first one must be running and wait the connection from the second. After when you type IP number or host name in the connect dialog box you'll be prompted for the available connection. Now you can type any text message and send it with the button SEND. You can try it also in the same computer to test it's functionality.
