推荐答案

你给出的例子不是串口 - 它是关于调制解调器的。

串口不够聪明，不知道连接到它们的是什么 - 调制解调器知道他们正在使用哪个串口。

您可以用这种方式枚举调制解调器（或其他设备）：



添加对system.management.dll到你的应用程序。

The example you give is not about serial ports - it is about modems.
Serial ports are not intelligent enough to know what is connected to them - modems know which serial port they are using.
You can enumerate modems (or other devices) in this way:

Add a reference to system.management.dll to your app.

 Imports System.Management
 Private Sub LoadModemList()
    Try
        Dim mngSearch As New ManagementObjectSearcher("Select * From Win32_POTSModem")
        Dim mngColl As ManagementObjectCollection = mngSearch.Get
        Dim mngObj As ManagementObject

        For Each mngObj In mngColl
            Debug.WriteLine(CType(mngObj.Item("AttachedTo"),
           String) & " - " & CType(mngObj.Item("Name"), String))
        Next

    Catch ex As Exception

    End Try

End Sub
