推荐答案

使用它在串行端口上进行写入

Use this, to write on serial port

Public Class Tester
    Public Shared Sub Main
    
        Dim com1Port As IO.Ports.SerialPort = Nothing
        Try
            com1Port = My.Computer.Ports.OpenSerialPort("COM1")
            com1Port.WriteLine("serialData")
            com1Port.Write("serialData")
            com1Port.Close()
        Catch ex As Exception
            Console.WriteLine(ex.Message)
        Finally
            If (com1Port IsNot Nothing) Then com1Port.Dispose()
            com1Port = Nothing
        End Try
    End Sub
End Class

获取所有端口的名称都使用此

Fot getting names of all port use this

Option Strict On
Imports System.Collections.ObjectModel
Public Module PortsTest
   Public Sub Main()
      Dim ports As ReadOnlyCollection(Of String) = _
      My.Computer.Ports.SerialPortNames
      For Each port As String In ports
         Console.WriteLine(port)
      Next
   End Sub
End Module
