C Source Code Serial Port Communication Visual Basic

UNIX systems provide two basic modes of input, canonical and non-canonical mode. In canonical mode, input is processed when a new line character is received. The receiving application receives that data line-by-line. This is usually undesirable when dealing with a serial port, and so we normally want to disable canonical mode.
Serial ports provide an easy way to communicate between many types of hardware and your computer. They are relatively simple to use and are very common among peripherals and especially DIY projects. Many platforms such as Arduino have built in serial communication so they are really easy to set up and use. Many times you may want your project to communicate with your computer in order to have a cool interactive output, a neat sensor that passes data to your computer, or anything else you could possibly dream up. In this tutorial, I will walk you through how to interface to a serial port on the computer side of things, using Microsoft's . net framework. The code examples in this tutorial are in C#, but can be easily transferred to Visual Basic, or Visual C++. This tutorial assumes that you have a very basic understanding of object oriented programing, and whatever language you choose to program in. Since we are mainly going to be using the System.IO.Ports.SerialPort class, HERE is a link to the full documentation by MSDN if you want to check out the rest of the class. I also found a great article explaining how to fix several common bugs relating to serial ports. Check it out if you get stuck with any odd errors. Feel free to post questions or feedback! I am always happy to hear constructive comments so I can make improvements.
could you please share your code on how we can send data from NODMCU to serial port and get data from serial port using C# MVC Web Application. I want to make the project. It will a great favor if you pay heed to my request.Thanks in Advance.Email: miansaqlain237@gmail.com
Well, I need to \"identify\" the string that is coming in and then compare to a pattern so that then I can split it and remove parts that are not needed. Although, sometimes it seems like the UART communication fails and one message scrambles up with another line, I dont know if it has to do with the hardware or with the program... The thing is, when I go to CCS, the terminal in there sometimes show the same error, wich I think it means that it has nothing to do with my code on Visual Studio...I would like to know if there is a way that I could remove that RM (I dont think \\r\\n interferes on the comparation with the pattern set) or any other strange thing that comes in through the serial that is not comparable to the pattern...Thanks!
Over time, I added features that were needed for specific communication requirementsthat we stumbled upon, such as non-standard Baud rates, port forwarding, time-stampingreceived data and sending/receiving hexadecimal values. The last two items werelater removed from the utility itself, for the sake of keeping the basic utilitysimple, and added back as plug-in filters.
In case Termite is not what you are looking for, some alternatives are:The Serial Port Monitorby Eltima Software has the ability to sniff communication from another program(without requiring a special cable) and the ability to monitor multiple serialports at the same time. Serial Port Monitor handles RS485/422 as well as RS232,and supports Modbus RTU and Modbus ASCII protocols.The HyperTerminal applet that comes with Microsoft Windows, or the third-partyHyperTerminal Private Edition.MCS Electronics providesthe free \"simpleterm\" utility amongst its downloads.
