//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.PortsusingSystem.IO.Ports;//Only one source can use a serial port at a time so encaposlation is importantclassMySerialPortClass:IDisposable//This is the class that will do most of the heavy liftingpublicSerialPort SerialPort get;privateset;//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.constint 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.constint 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.constParity DefaultParityBit = Parity.None;//Stop bits or period is to mark the end of a message.
