I am trying to make a program in vb 2005 to real all the data from a device connected on Serial Port (Com 1).
i did this:
Imports System Imports System.IO.Ports Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load SerialPort1.Open() End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click If SerialPort1.IsOpen Then With RichTextBox1 .AppendText(SerialPort1.ReadLine & vbCrLf) .ScrollToCaret() End With End If SerialPort1.Close() End Sub
this code only give me the first line of the data that i will receive. If i try read existing nothing hapens. please help me:
the data storage on serial port device is like this:
110002+00000010 21.102+25166290 22.102+32314650 31..10+00000000
