Rudy: Not sure what your code does, but I'll see if I can figure it out. I hope someone has something more direct. Close() End Try End Sub End Class This is a kludgy solution. FormClosed Try SP.Dispose() Catch ex As Exception Me. Close() Exit Sub End Try End Select Tmr.Start() End Sub Private Sub Form1_FormClosed( ByVal sender As Object, ByVal e As FormClosedEventArgs) Handles Me. Load TB.Multiline = True TB.ScrollBars = ScrollBars.Both TB.Dock = DockStyle.Fill TB.Parent = Me Tmr.Tag = "NewPort" Tmr.Start() End Sub Sub Tmr_Tick( ByVal sender As Object, ByVal e As EventArgs) Handles Tmr.Tick Tmr.Stop() Select Case CType (Tmr.Tag, String ) Case "NewPort" Dim Ports() As String = SerialPort.GetPortNames Dim I As Integer For I = 0 To Ports.Length - 1 If Ports(I) = "COM3" Then Exit For Next If I < Ports.Length Then SP = New SerialPort( "COM3" , 4800) Tmr.Tag = "OpenPort" End If Case "OpenPort" Try SP.Open() Tmr.Tag = "PortOpen" Catch ex As Exception 'retry End Try Case "PortOpen" Try TB.AppendText(SP.ReadLine + Environment.NewLine) Catch ex As Exception Me. Module Module1 Sub main() Do Dim GPSFrm As New Form1 If Not GPSFrm.ShowDialog() = Then Exit Do Loop End Sub End Module Imports System.IO.Ports Imports Public Class Form1 Dim SP As SerialPort Dim WithEvents Tmr As New Timer Dim TB As New TextBox Private Sub Form1_Load( ByVal sender As Object, ByVal e As System.EventArgs) Handles Me. Here's code that lets the USB be unplugged and replugged with the only visible indication the data stops scrolling. Good programmers write code that humans understand.
Any fool can write code that a computer can understand. The result is that the synchronization is lost and cannot be regained so you cannot use any of the modern communication methods like 9th bit communication or telegram separation by means of Break :-(Įverything should be made as simple as possible, but not simpler. I have my own problems with that implementation because Microsoft is so "clever" as to take 11 bits from the Receiver FIFO in the UART, throw the 3 vital status bits away (after firing events) and then stores the result in a 16-bit stream. Long time ago, Justin Van Pattern, who is - or at least were - in charge of this, promised me a collaboration about a modern SerialPort implementation, but nothing happens. Net 3.5 SP1, SerialPort seems to work again by some miracle, but the bug is still not fixed and it is obviously a wasp's nest, which nobody dare to touch. Net 3.5 RTM became completely useless for all serialPort applications and nobody knew why or ever found out! In.
I don't know if it was this attempt that coursed it, but. First they told me that they didn't dare to try to fix the bug because they would not risk the system to become unstable !!! In. It seems that Microsoft has given up on this. The damage has been done and the port cannot close. It is too late to try to dispose SerialPort when the departure message gets processed by WndProc. The moment you pull the plug, it is "good buy" and you can do nothing about it. I don't think that the message will help you.
