I am Thai and i need to send and receive my language using OpenNETCF.IO.Serial  .

 my Application run at wince 4.2  so i don't want to use CF 2.0

Can someone help me plzzz 

 

Thank you 

 I don't understand what the problem would be.  Just send it as bytes, and it'll happily send them over the serial connection.  I regularly send raw binary data across the serial port and have no issues at all with any of the values.  The trick is to use bytes and not characters or strings.

 the problem is when i send Ascii code over 127  it always return to zero again

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim buffer(6) As Byte
        buffer(0) = 125
        buffer(1) = 126
        buffer(2) = 127
        buffer(3) = 128
        buffer(4) = 129
        buffer(5) = 130
        SerialPort1.Output() = buffer
    End Sub

Rx  125 126 127 000 001 002  << when Hyperterminal has received

 

 

It could be that Hyperterminal is doing something funky. Have you written an app to determine this?

Its looking like you might have your connection set up for 7 bit, instead of 8 bit.  Double check the connection settings between the two machines and double-check what hyperterminal is doing.  It could very well be that you're fighting a mis-configuration of hyperterminal.
