Poz,

Ubacio sam referncu i sve normalno radi samo sad ne znam postaviti parametre u aplikaciji Pariti, Stopbits...... I napraviti READ sa tog porta ? Jeli ima netko nekakvog koda (example) da mi pomogne?? Help
evo mog koda

Imports System.IO.Ports
Public ReadOnly Property SerialPortNames As System.Collections.Generic.ReadOnlyCollection`1(Of String)

Public Class Form1
Function ReceiveSerialData() As String
' Receive strings from a serial port.
Dim returnStr As String = ""

Using com4 As IO.Ports.SerialPort = _
My.Computer.Ports.OpenSerialPort("COM4")
Do
Dim Incoming As String = com4.ReadLine()
If Incoming Is Nothing Then
Exit Do
Else
returnStr &= Incoming & vbCrLf
End If
Loop
End Using

Return returnStr
End Function



Private Sub GetSerialPortNames_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
' Show all available COM ports.
For Each sp As String In My.Computer.Ports.SerialPortNames
ListBox1.Items.Add(sp)
Next
End Sub
Dim returnStr As String
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
