System.IO.Ports Namespace

The System.IO.Ports namespace contains classes for controlling serial ports. The most important class, SerialPort, provides a framework for synchronous and event-driven I/O, access to pin and break states, and access to serial driver properties. It can be used to wrap Stream objects, allowing the serial port to be accessed by classes that use streams.

Classes

SerialDataReceivedEventArgs

Provides data for the DataReceived event.

SerialErrorReceivedEventArgs

Prepares data for the ErrorReceived event.

SerialPinChangedEventArgs

Provides data for the PinChanged event.

SerialPort

Represents a serial port resource.

Enums

Handshake

Specifies the control protocol used in establishing a serial port communication for a SerialPort object.

Parity

Specifies the parity bit for a SerialPort object.

SerialData

Specifies the type of character that was received on the serial port of the SerialPort object.

SerialError

Specifies errors that occur on the SerialPort object.

SerialPinChange

Specifies the type of change that occurred on the SerialPort object.

StopBits

Specifies the number of stop bits used on the SerialPort object.

Delegates

SerialDataReceivedEventHandler

Represents the method that will handle the DataReceived event of a SerialPort object.

SerialErrorReceivedEventHandler

Represents the method that will handle the ErrorReceived event of a SerialPort object.

SerialPinChangedEventHandler

Represents the method that will handle the PinChanged event of a SerialPort object.

Remarks

The namespace includes enumerations that simplify the control of serial ports, such as Handshake, Parity, SerialPinChange, and StopBits.
