This could possibly be because something else is already running on port 1234, so try changing the port to something else, like 2012. For example:

Server code change:

ss = new ServerSocket(2012, 512, 3);

Client code change:

cs = new ClientSocket("127.0.0.1", 2012, 512);

Then, when you run the client (which you’ll need to do “standalone” if you’ve just run the server through Visual Studio [i.e. you'll need to launch the client exe from windows explorer or the command line]) make sure you have the SDL.dll and SDL_net.dll files copied into the same location as the client executable, as it says in the Notes on building for WIndows section.

Also, it just occurs to me that your firewall could, potentially, be blocking applications from opening ports, so you might want to try temporarily disabling it and trying again if the above doesn’t solve your problem.

Hope this helps.

I was wondering if SDL can be used to create a socket to a client passing through a proxy. I did not find any documentation about it yet.

There’s also the issue of moving the text carat back one character, which you could get around by re-displaying the prompt each time, but that’s not very elegant. It’s all do-able, it just might be a little fiddly to nail it with a nice cross-platform solution.

I have some problems when using BACKSPACE. Any idea for solving it?
