Problems With Serial Ports in Windows Server 2003

[Daniel]

Ive used the New Serial Port Namespace in Net Framework 2 to write a Serial
Port Monitoring Application. Basically the program opens the serial port and
listens for any data that is received. It then added it to a Rich Text Box
showing the data in either Hex or Text as well as any control characters.

The program works perfectly on Windows XP but when I transfer it to a
machine running Windows Server 2003, nothing happens. By that I mean that no
data shown in the Text Box. I added some logging to the prorgam which just
writes data to a text file. The Serial Port is being opened successfully,
but the method which is called when data is waiting in the buffer never seems
to be called even though the serial device is definitely sending data.

For testing Im using the following Code :-
port.DataReceived += new SerialDataReceivedEventHandle (port_DataReceived);
private void port_DataReceived(object sender,
SerialDataReceivedEventArgs e)
{
// Show all the incoming data in the port's buffer
Console.WriteLine(port.ReadExisting());
}

On the Server I have installed the Net Framework 2.

Can anyone provide any assistance?

Thanks,
Daniel.
