在vb2005环境下，简单的串口初始化和接收，问题：在初始化和接收到数据时，总是返回一些信息，怎样设置才能使板子不发送这些信息？

程序如下：
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
SerialPort1.PortName = "COM1"
SerialPort1.BaudRate = 19200
SerialPort1.DataBits = 8
SerialPort1.StopBits = IO.Ports.StopBits.One
SerialPort1.Parity = IO.Ports.Parity.None
SerialPort1.ReceivedBytesThreshold = 100
SerialPort1.Open()

End Sub
Private Sub SerialPort1_DataReceived(ByVal sender As System.Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles SerialPort1.DataReceived
Dim CS(1000) As Byte
Dim n As Int32
n = SerialPort1.BytesToRead
SerialPort1.Read(CS, 0, n)
End Sub
End Class

返回如下：
初始化后：
AKY=00001005 PC=02a32840(ser2440.dll+0x00002840) RA=02a3282c(ser2440.dll+0x00002
82c) BVA=06000000 FSR=00000007
Data Abort: Thread=8f810784 Proc=8e026160 'device.exe'
AKY=00001005 PC=02a32840(ser2440.dll+0x00002840) RA=02a3282c(ser2440.dll+0x00002
82c) BVA=06000000 FSR=00000007
Data Abort: Thread=8f810784 Proc=8e026160 'device.exe'
AKY=00001005 PC=02a32840(ser2440.dll+0x00002840) RA=02a3282c(ser2440.dll+0x00002
82c) BVA=06000000 FSR=00000007
接收到数据时返回：
+SL_GetStatus 0x38250
+SL_GetStatus 0x38250
+SL_GetStatus 0x38250
+SL_GetStatus 0x38250

可以试试新的wince5 bsp，对串口驱动有所改进。

我这板子是别人的，2年前的，系统也是。你要能帮我确定使者的问题，我就换个新的。
