rxtx

I want to detect the device through serial port using RxTx in java and device is programmed that if it recieves a specific word from computer it will reply "ok" and if the computer receives ok.. it will stop sending the word and highlight that the device is attached. PLEASE HELP ME. and one more thing.. i have to check for every port.. please will you code a method that auto-cycle through the ports till the device is detected. My code sends the word only one time even being in a infinite loop. code: private void cb1KeyPressed(java.awt.event.KeyEvent evt) { // TODO add your handling code here:

Finally managed to read from rxtx in windows but now I just cannot make it work in Ubuntu.I get the rxtx libs using apt-get ,but when i run the application,i can not see anything,tried a couple of try-catch blocks and i don't even get the exceptions,and since Ubuntu based debugging is not possible for now, i can not pinpoint the problem. (Ubuntu is 12.04 64 bit). import gnu.io.*; import java.io.*; import javax.swing.JOptionPane; public class ReadComPort { public static void main(String[] s) { readcomport(); } public static String readcomport() { String value = null; try { // CommPortIdentifier

UPDATE: I have found a solution by using the jSerialComm library. (see code at the bottom) I have a program that we have been running for quite a while on windows 7 machines, but now are starting to introduce machines with Windows 10, and the program crashes. So i need to find a solution. The error is an EXCEPTION_ACCESS_VIOLATION error. (See below) The first block of code below is my own code which uses the rxtxSerial.dll library. It will open and set the port parameters, but crashes as soon as data is received from the port. I have also tried the jssc.jar library with the same EXCEPTION

I have RXTX installed on a Mac. Both a Java JAR program and the Arduino software see the Arduino as a USB modem if it is Both claim the port is "already in use" if we try to open the serial port. Both claim "Unknown User". I have the rxtxcomm.jar in the Java Extensions. How do I get either of these to work? mkstlwtz The OS X has some kind of exclusion mechanism on the serials ports. The MacBook does not have any serial ports, but the USB ports emulate them. When the Arduino is hooked up, it appears in the port list as "/dev/tty.usbmodem..." where ... are some trailing digits. When is said the
