How do i convert a string to bytes?
I want to send raw bytes out the serial control.

Private Sub Rs232SendData(B yVal cmd As String)

Try

cmd=cmd & vbCrLf

'Convert it to byte data here

??????????????? ??????????

SerialPort1.Wri te(byteData)

txtData.AppendT ext(Now.ToShort TimeString & "->Sent: " & cmd)

Catch ex As System.Exceptio n

MessageBox.Show (ex.Message)

Depending on what encoding you're using (ASCII in this case):

System.Text.ASC IIEncoding.ASCI I.GetBytes(MySt ringHere)

If it's another encoding type, swap ASCIIEncoding with the other classes.

Lou,

Maybe this page gives an explanation

Use only ASCII if you are sure that you are only the 7 less significant
bites from a byte (127bits) as ASCII is only for that. It is using in a lot
of countries different code pages and gives therefore different results as
it is used in that if it is about the full byte.
