This example sends a string to the COM1 serial port. You may need to use a different serial port on your computer.Use the My.Computer.Ports.OpenSerialPort method to obtain a reference to the port. For more information, see OpenSerialPort.The Using block allows the application to close the serial port even if it generates an exception. All code that manipulates the serial port should appear within this block or within a TryCatchFinally block.The WriteLine method sends the data to the serial port. VB
