![]() SerialPort = (SerialPort) portId.open(this.getClass(). Private static final int DATA_RATE = 9600 Įnumeration portEnum = CommPortIdentifier.getPortIdentifiers() ĬommPortIdentifier currPortId = (CommPortIdentifier) portEnum.nextElement() Private static final int TIME_OUT = 2000 The PC program should keep the serial port open until it is completely finished with the Arduino. That does not work with an Arduino as it resets when the PC opens the serial port. Private static final String PORT = "COM32" A common problem is for a PC program to open the serial port, send a message and then close it. You can access the available ports using array index notation. This is the method which'll initialize the serial port.

How can I make my program to read serial port values when it is started without doing anything to external devices. I need to know whether there's a way to fix this.
