read data from serial port RRS feed

  • Question

  • hi

    how  to read contact names in phone and sms messages and view them in DataGridview via Serial Port?

    I deal with the Serialport and actually sent messages to the mobile phone, but I did not find information on how to withdraw the names and messages from the phone.

    Thank you for posting here.

    Generally, we can use the following code to read data from serial port.

        Private port As SerialPort = New SerialPort("COM1", 9600, Parity.None, 8, StopBits.One)
        Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
            AddHandler port.DataReceived, AddressOf post_DataReceived
        End Sub
        Private Sub post_DataReceived(ByVal sender As Object, ByVal e As SerialDataReceivedEventArgs)
            Dim str As String = port.ReadExisting()
        End Sub

    Besides, here's a reference you may need.
