Hello again :)
I have another problem : Iīd like to access serial interface on my ARM box with RXTX.
I use this code :
public class SimpleWrite {
static Enumeration portList;
static CommPortIdentifier portId;
static String messageString = "Hello, world!\n";
static SerialPort serialPort;
static OutputStream outputStream; public static void main(String[] args) {
portList = CommPortIdentifier.getPortIdentifiers();while (portList.hasMoreElements()) {
portId = (CommPortIdentifier) portList.nextElement();
if (portId.getPortType() == CommPortIdentifier.PORT_SERIAL) {
// if (portId.getName().equals("COM1")) {
if (portId.getName().equals("/dev/ttyS3")) {
System.out.println("test");
try {
serialPort = (SerialPort) portId.open("SimpleWriteApp");
System.out.println("ok");
} catch (PortInUseException e) {
System.out.println("not ok");
}
and I have only the output ītestī .
When I run gdb I have this :
Starting program: /home/java/kaffe/jre/bin/kaffe-bin SimpleWrite [New Thread 16384 (LWP 1198)] Devel Library ========================================= Native lib Version = RXTX-2.1-7pre16 Java lib Version = RXTX-2.1-7pre16 test 1
