Note: it is not possible to use TCP if you have Matlab at both ends, but you can use tcp to a non-Matlab server, or you can use UDP to connect to Matlab systems, provided that you bind the local port.

Your help is doing great for me. thanks in advance hope to see your reply soon.

I don't know about the echo server. You may wish to use the Matlab File Exchange IP toolbox, http://www.mathworks.com/matlabcentral/fileexchange/345-tcpudpip-toolbox-2-0-6 |
