Following SocketServer / SocketClient example :

Server :

#include <Core/Core.h>

using namespace Upp;

CONSOLE_APP_MAIN
{
	TcpSocket server;
	if(!server.Listen(3214, 5)) {
		Cout() << "Unable to initialize server socket!\n";
		SetExitCode(1);
		return;
	}
	Cout() << "Waiting for requests..\n";
	TcpSocket s;
	if(s.Accept(server)) {
		while(!s.IsError()){
			String w = s.GetLine();
			Cout() << "Request: " << w << " from: " << s.GetPeerAddr() << '\n';
			if(w == "time")
				s.Put(AsString(GetSysTime()));
			else
				s.Put(AsString(3 * atoi(~w)));
			s.Put("\n");
		}
	}
	Cout() << "Stopping server..\n";
}

Client :

#include <Core/Core.h>

using namespace Upp;

CONSOLE_APP_MAIN
{
	TcpSocket s;
	if(!s.Connect(CommandLine().GetCount() ? CommandLine()[0] : "127.0.0.1", 3214)) {
		Cout() << "Unable to connect to server!\n";
		SetExitCode(1);
	}
	s.GlobalTimeout(1000);
	s.Put("time" + '\n');
	Cout() << s.GetLine() <<EOL;
	s.Put("hello" + '\n');
	Cout() << s.GetLine() <<EOL;
}

Here is what I get in my console :

What I'm doing wrong ? the SocketServer / SocketClient work fine but it only use the socket once to send and receive data once before closing it
