小弟初學VB編程，現在想實作串口通信，知道是用MSComm控制元件，但是程式不會，求大神們解答，點燃我編程的激情，謝謝！
我找到一個范例，程式除錯成功，但是結果不正確。程式如下：
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.AxMSComm1.CommPort = ComboBox1.Text
AxMSComm1.DTREnable = True “打開串口”
Button1.Enabled = False
End Sub
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
AxMSComm1.Output = TextBox1.Text “發送資料”
MsgBox("資料發送成功")
End Sub
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
TextBox2.Text = AxMSComm1.Input “接收資料”
MsgBox("資料接收成功")
End Sub
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ComboBox1.Text = 1 “默認串口號為1”
End Sub
End Class
現在運行程式后，點擊打開串口，然后游標在“發送資料框”內，輸入資料，比如：abcd，點擊發送資料按鈕，彈出如圖所示情況：
怎么辦，求大神們解答，急！
