Problem using serial port in vb2005

Hello,

I want to send some simple strings to com1 using vb2005. I want to read it
in Hyperterminal.
I succeeded to send some data en read it in Hyperterminal, only the data I
received is not the data I send.

This is the code i used:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
        SendSerialData()
End Sub

Sub SendSerialData()
        Dim data As String = "x"

        ' Send strings to a serial port.
        Using com1 As IO.Ports.SerialPort =
My.Computer.Ports.OpenSerialPort("COM1", 2400, IO.Ports.Parity.None, 8, 1)

       com1.WriteLine(data)
     End Using
End Sub

Is there something I forgot?
The settings of the serial port I also used for hyperterminal.

Thank you very much for even reading my question

You will have to be more specific about what went wrong. How is the
data you received different than what you sent? Is it *completely*
different? Or are you just missing some information?

You said the settings in Hyperterminal and the serial port were the
same. Are you using the same handshaking? Is it hardware handshaking
or are you using XOn/XOff? How much data are you sending?
