Hi!
I am new to serial port connections. And the first thing that I want to do is to see all available com ports in a combo box but for some reason the code that I got would not work.

Currently I have a serial device connected with my computer. Also, when I used hyperterminal the serial device is working fine and I could see the com ports.

So where did I go wrong?
Below is the code I used to display the port names and it comes from MSDN help.
    Sub GetSerialPortNames()
        ' Show all available COM ports.
        For Each sp As String In My.Computer.Ports.SerialPortNames
            cmbPortName.Items.Add(sp)
        Next
    End Sub 'Supposed to get available com ports
