	ReadByte	Synchronously reads one byte from the SerialPort input buffer.
	ReadChar	Synchronously reads one character from the SerialPort input buffer.
	ReadExisting	Reads all immediately available bytes, based on the encoding, in both the stream and the input buffer of the SerialPort object.
	ReadLine	Reads up to the NewLine value in the input buffer.
	ReadTo	Reads a string up to the specified value in the input buffer.
	ToString	Overloaded.
	Write	Overloaded. Writes data to the serial port output buffer.
	WriteLine	Writes the specified string and the NewLine value to the output buffer.

	Name	Description

	DataBits	Gets or sets the standard length of data bits per byte.
	DesignMode	Gets a value that indicates whether the Component is currently in design mode. (Inherited from Component.)
	DiscardNull	Gets or sets a value indicating whether null bytes are ignored when transmitted between the port and the receive buffer.
	DsrHolding	Gets the state of the Data Set Ready (DSR) signal.
	DtrEnable	Gets or sets a value that enables the Data Terminal Ready (DTR) signal during serial communication.
	Encoding	Gets or sets the byte encoding for pre- and post-transmission conversion of text.
	Events	Gets the list of event handlers that are attached to this Component. (Inherited from Component.)
	Handshake	Gets or sets the handshaking protocol for serial port transmission of data.
	IsOpen	Gets a value indicating the open or closed status of the SerialPort object.
	NewLine	Gets or sets the value used to interpret the end of a call to the ReadLine and WriteLine methods.
	Parity	Gets or sets the parity-checking protocol.
	ParityReplace	Gets or sets the byte that replaces invalid bytes in a data stream when a parity error occurs.
	PortName	Gets or sets the port for communications, including but not limited to all available COM ports.
	ReadBufferSize	Gets or sets the size of the SerialPort input buffer.
	ReadTimeout	Gets or sets the number of milliseconds before a time-out occurs when a read operation does not finish.
	ReceivedBytesThreshold	Gets or sets the number of bytes in the internal input buffer before a DataReceived event occurs.
	RtsEnable	Gets or sets a value indicating whether the Request to Send (RTS) signal is enabled during serial communication.
