Hello!

I have been playing successfully with sockets based in SocketServer ans SocketClient demos.

However I have had problems with a simple program that sends plain text messages ended with a '\n with:

char *buf = "Message\n";
send(socket, buf, strlen(buf), 0);

Looking to SocketServer demo, it seems that s.Accept(server) blocks the program the second time. I mean:
- 1st s.Accept(server) passes just when demo program begins to send messages
- s.GetLine() works properly
- 2st s.Accept(server) blocks the program

However, if s.GetLine() is called in a loop, it takes all the messages properly.

Is there any kind of protocol embedded in TcpSocket used the way is used in SocketServer/Client demos, that does not match with plain send() calls?

Just to be sure: Do you open a new connection to the server for second 'send'? (the whole testcase would be useful).
