我如何将相同的串行端口用于另一种形式

Question

请问我怎样才能使用相同的端口到另一个我的程序form2。 我程序中的当前情况是我成功接收来自表格1的数据但我没有成功接收来自表格2的数据。下面是我的表格2数据接收代码

 Private Sub Scanner1_DataReceived(ByVal sender As System.Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles Scanner1.DataReceived
    dataIn = Scanner1.ReadExisting
    SetText(dataIn)
End Sub
Delegate Sub SetTextCallback(ByVal text As String)
Private Sub SetText(ByVal text As String)
    If Me.txtSearch.InvokeRequired Or Me.txtSearch1.InvokeRequired Then
        Dim d As SetTextCallback = New SetTextCallback(AddressOf SetText)
        Me.Invoke(d, New Object() {text})
    Else
        Me.txtSearch.Text = text.ToString
        Me.txtSearch1.Text = text.ToString
    End If
End Sub
