There are many public properties, but except these three, all properties will have default values. ReadTimeout: Gets or sets the number of milliseconds before a timeout occurs when a read operation does not finish.StopBits: Gets or sets the standard number of stopbits per byte.BaudRate: Gets or sets the serial baud rate.The public properties of SerialPort class that we will use are: The default communication port will be COM1. For example, the value of DataBits defaults to 8, and StopBits defaults to 1. But I am using the parameter less constructor, the constructor uses default property values. In all, there are seven public constructors for creating SerialPort. To create a SerialPort object, all we need to do is: Open(): Opens a new serial port connection.The written output includes the New Line string. WriteLine(string): Writes the specified string and the New Line value to the output buffer.If a New Line is not found before timeout, this method returns a null value. ReadLine(): Reads up to the NewLine value in the input buffer.The methods of SerialPort class that we will use are: Creating SerialPort Objectīy creating an object of this type, we will be able to programmatically control all aspects of serial communication. That is, SerialPort class represents a serial port resource. It can be used to wrap Stream objects, allowing the serial port to be accessed by classes that use streams. SerialPort class provides a framework for synchronous and event-driven I/O, access to pin and break states, and access to serial driver properties. The most important class is the SerialPort class. The System.IO.Ports namespace contains classes for controlling serial ports. In full duplex mode, here I am not going to use any handshaking or flow control, I will use null modem connection for communication. We will be using RS 232 C standard for communication between PCs. The new framework provides classes with the ability to access the serial ports on a computer, and to communicate with serial I/O devices. The framework provides System.IO.Ports namespace. NET framework version 2.0 (beta) provides features for serial communication. In this article, I will give you an introduction on how to do serial port communication on.
