掃描裝置上的GPS是哪一個COM
在" 在PDA上開發GPS的程式問題 這篇文章中,有提到要如何去看GPS是在哪一個COM Port上面;一般來說有兩個方式,一個是自己去掃描,另一種方式就是借助別人的軟體去看了;下面這邊我做了一個簡單的掃描程式,有興趣的朋友可以參考看看 Imports System.IO.Ports Imports System.Text Public Class Form1 Dim strPortName As String = "" Dim strTmp As String = "" Dim B(199) As Byte Dim intReturn As Integer = 0 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load SerialPort1.BaudRate = 4800 SerialPort1.DataBits = 8 SerialPort1.Handshake = Handshake.None SerialPort1.StopBits = StopBits.One SerialPort1.Parity = Parity.None SerialPort1.ReadTimeout = 2500 For Each s As String In SerialPort.GetPortNames SerialPort1.PortName = s Try SerialPort1.Open() Threading.Thread.Sleep(200) intReturn = SerialPort1.Read(B, 0, B.Length) If intReturn > 0 Then strTmp = Encodi...
