Serial Port strange data display and crash - vb.net

Question

I am trying to create vb.net program to get data from scales using serial port.
I don't know scales model, just Display model: IND231.
Problem is i get stupid data:
but if turn on Putty i get this:
As you see in putty there is only one line which refresh every sec, true weight is first two 00 (in middle), in my situation this line is not refreshing, but make a huge line and after 5-10 s, my program just crash.
My program code is:
Imports AxSerial
Public Class Form1
Dim Q As Queue(Of String) = New Queue(Of String)
Private Sub Form1_Load(ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles MyBase.Load
For Each s In System.IO.Ports.SerialPort.GetPortNames()
lstPorts.Items.Add(s)
Next s
End Sub
Private Sub btnStart_Click(ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles btnStart.Click
Try
If lstPorts.SelectedIndex = -1 Then
MsgBox("Please select a port")
Exit Sub
Else
SerialPort1.BaudRate = 9600
SerialPort1.DataBits = 8
SerialPort1.Parity = IO.Ports.Parity.None
SerialPort1.StopBits = 1
SerialPort1.RtsEnable = False
SerialPort1.PortName = lstPorts.SelectedItem.ToString
SerialPort1.Open()
Timer1.Start()
End If
Catch ex As Exception
MsgBox(ex.Message)
End Try
End Sub
Private Sub SerialPort1_DataReceived(ByVal sender As System.Object,
ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) _
Handles SerialPort1.DataReceived
Q.Enqueue(SerialPort1.ReadExisting())
End Sub
Private Sub Timer1_Tick(ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles Timer1.Tick
SyncLock Q
While Q.Count > 0
txtReceived.Text &= Q.Dequeue
End While
End SyncLock
End Sub
Private Sub btnStop_Click(ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles btnStop.Click
SerialPort1.Close()
Timer1.Stop()
End Sub
End Class
This is IND321 Serial Port Parameters
SerialPort1.BaudRate = 9600
SerialPort1.DataBits = 8
SerialPort1.Parity = IO.Ports.Parity.None
SerialPort1.StopBits = 1
SerialPort1.RtsEnable = False
Im not sure with RtsEnable, i think this is FlowControl.
What i need to correct to get data like putty?

Answer 1

It looks like your scale/serial port is returning data in another format.
Check your scale specs. It might be e72 or some other even/odd/bits/parity combination.
