Solution 1

You have to write code from scratch, following the same logic. The class you need is System.IO.Ports.SerialPort:
SerialPort Class (System.IO.Ports)[^].

Dear All,

Thanks for your help.

Imports System.IO.Ports
Imports System.Net.Sockets
Imports System.Text

Now in button event
I write this code:

m_arTxBfx(0) = &H7E
m_arTxBfx(1) = m_InputLength + 2
m_XOR = 255
m_SUM = 0
For i = 2 To m_InputLength + 1
m_XOR = m_XOR Xor m_arTxBfx(i)
m_SUM = m_SUM + m_arTxBfx(i)
Next
m_arTxBfx(m_InputLength + 2) = m_XOR
m_SUM = m_SUM + m_XOR
m_SUM = m_SUM And 255
m_arTxBfx(m_InputLength + 3) = m_SUM

temp = "Send: "
For i = 0 To m_InputLength + 3
'temp =Temp+Conversion .Hex (m_arTxBfx(i),2)+' '
Next
txtSend.Multiline = True

myres = 1
Dim inputlength As Integer = m_InputLength + 4

If mySerialPort.IsOpen = True Then
mySerialPort.DiscardInBuffer()
mySerialPort.Write(m_arTxBfx(0), inputlength)
End If

But Its showing error over the line (mySerialPort.Write(m_arTxBfx(0), inputlength)) Please help...
