I made a short look at your VI. JB's answer is the one thing I also have seen.
Another thing is setting the parameters for the communication.
In hyperterminal are the flow control (SW/HW handshake) also disabled? You configured the baudrate and byte parameters but the flow control is set to default which means no handshake.
