c# print all received from serial code example

Example: c# serial port

//Serial Ports are used to communicate with other independant devices over 
//a serial COM. More at https://en.wikipedia.org/wiki/COM_(hardware_interface) and https://en.wikipedia.org/wiki/Serial_communication
//For windows .NET Framework (This will not work in .net core or on linux)
//You will be using IO.Ports
using System.IO.Ports;

//Only one source can use a serial port at a time so encaposlation is important
class MySerialPortClass : IDisposable
{
  	//This is the class that will do most of the heavy lifting
	public SerialPort SerialPort { get; private set; }

	//diffenent devices use diffent baud rates or rates of electrical symbol 
  	//change. This will cause diffent rates of communication, but both devices 
	//must agree on a rate to exchange at. The most common is 6800 bauds.
  	const int DefualtBaudRate = 6800;
  	//The above is also true of the amount of bits in a attomic ecnoding in a 
  	//message.The most common is 8 bits for a byte. Honesly this one rarely changes.
  	const int DefaultSize = 8;
  	//The same is true of the party bit. The party bit is to detect error.
	//Hardware is often good enough now that is is not used often, but it adds
	//a bit to the start and sets it to make sure the number of set bits is odd
	//or even. Or it can be used to just mark the start, but stop bits are 
  	//enough usally to mark at the end.
  	const Parity DefaultParityBit = Parity.None;
	//Stop bits or period is to mark the end of a message. Usally one bit is used.
	const StopBits DefaultStopBits= StopBits.One;
  
  	//since only one source can access a com at a time you may want to expose 
  	//if it is open. It will also be useful for resource freeing after.
  	public bool Open { get; private set; } = false;
  	//It will also be useful for resource freeing after.
	private bool Disposed { get; private set; } = false;
  	
  	//In Constructor we should set all the com vars. But the one we havent
    //defined a default yet is the com port name. This will change depeneding
   	//on the plug used or if a virual (USB) on is used. Check your 
  	//'Device Manager' for valid ports it could be.

	//after all the set up you must open the port. If the port is in use you

	void OpenPort()

    	Open = true;
      	SerialPort.Open();
    }

	//reading and writeing is simple after set up and opening, but for each 
	//device messages will have to be formated differntly. Check with your
	//devices manual or data sheets for more on formatting.
