You say that the server doesn't normally send anything back to the client - do you mean it connects and then waits for the client to send something, and only then returns data ? If so, then you could use a telnet monitor to send a particular string and look for a particular reply.
If you only want to check whether the TCP three-way-handshake was successful, you can use a TCP monitor with no send or receive string specified. This will only test the 3WHS and nothing more.
You could also potentially use a TCP half-open monitor, which sends a SYN, and marks up if it gets a SYN+ACK in reply (if the port is closed, it gets a RST).
