Apr 06, 2012 Serial port data can be read in many ways and many devices communicate via the serial port. In my project I had the need to implement serial port communication for a RFID reader. This is a sample example to read data from the serial port and display. Use this class to control a serial port file resource. This class provides synchronous and event-driven I/O, access to pin and break states, and access to serial driver properties. Additionally, the functionality of this class can be wrapped in an internal Stream object, accessible through the BaseStream property, and passed to classes that. Mar 25, 2016 Hello folks, Visual Basic.net is an easy to learn language from Microsoft for the windows platform.One of the cool features of Visual Basic.net is the ability to whip up good looking gui components with a few lines of code. In this tutorial we are going to use Visual Basic.net to program your PC's Serial Port and communicate with an embedded microcontroller like MSP430 or 8051. Arduino & Visual Studio - Serial Communication: The reason for this project is to show you, how to manage Serial connections in Visual Studio 2015 with VisualBasic as the main programming language.A few days ago, I copyed a project from VisualBasic 2010 to Visual Studio inside a VisualBasic pro. This topic describes how to use My.Computer.Ports to receive strings from the computer's serial ports in Visual Basic. To receive strings from the serial port. Initialize the return string. Dim returnStr As String = ' Determine which serial port should provide the strings. This example assumes it is COM1.

You must set all the properties of your serialPort1.
Also, you should try to debug at multiple place to help us where it's going wrong : Does IsOpen return true? if no, this explain why you receive nothing.
See MSDN example if you want to try something is supposed to work : http://msdn.microsoft.com/en-us/library/system.io.ports.serialport.aspx
Be sure that the serial port is not alerady open by another program and you have selected the good COM PORT. Otherwise the code looks good. (You could also looks in the RxString value each time you are passing by. (maybe many empty space or '/r'))
