I am creating simple java application using java RXTX library. Application will send data(from windows xp) to arduino(open source micro controller) which will display the received data on LCD display. When i send the data to arduino, arduino will reset itself. So it do not display the data. I can prevent arduino reset by connecting RST pin to 5v pin.(Hardware solution). Is their any software way to make windows DTR off in java code or java rxtx.
