串口（com端口）读取数据

Question

我有一个情人1雷达以及V1Connect（蓝牙适配器），它通过虚拟串行端口（COM 16）连接到我的PC。

我正在尝试阅读来自它的数据，但我得到的只是胡言乱语。

我的VB.net代码是这样的：

Private pendingMsg As New stringbuilder

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 SerialPort1_DataReceived(ByVal sender As System.Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles SerialPort1.DataReceived
    Dim b As Integer

    SerialPort1.ReadTimeout = 50

    Try
        Do While SerialPort1.BytesToRead > 0
            b = SerialPort1.ReadByte
            Me.BeginInvoke(New mydel(AddressOf txt_out), b)
        Loop
    Catch ex As Exception

    End Try
End Sub

Private Sub txt_out(ByVal i As Integer)
    txtReceived.AppendText("&H" & i.ToString("X2") & " ")
End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    SerialPort1.BaudRate = 57600
    SerialPort1.DataBits = 8
    SerialPort1.Parity = IO.Ports.Parity.None
    SerialPort1.StopBits = IO.Ports.StopBits.One
    SerialPort1.PortName = "COM16" 'lstPorts.SelectedItem.ToString
    SerialPort1.Open()
End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
    SerialPort1.Close()
    txtReceived.Text = ""
End Sub

输出是这样的：

我看到＆amp; HAA（开始）和＆amp; HD8（结束），但我如何分开这些开始和结束而不继续添加？
