HOW to read from serial port in visual basic

[Deexith Hasan]

Dim a As String = SerialPort1.ReadByte
        If a Is Nothing Then
            Exit Sub
        Else
            RichTextBox2.Text = a

        End If

i used the above code to read from serial port but my application hangs here..... whats the mistake?
