    Default Re: Java Serial Communication using Javax.comm and saving variables into an array

    Hi Everyone;

    Can somebody help how to get the output from the serial port to a variable that i can use in another class.

    I mean to say, in the below method, the code: System.out.print(new String(readBuffer)); gives the output to the output terminal but I want to store this output and use the output in another class.

    Please help.


    public void serialEvent(SerialPortEvent event) {

    // System.out.println("In Serial Event function().. " + event +
    // event.getEventType());
    switch (event.getEventType()) {
    /*
    * case SerialPortEvent.BI: case SerialPortEvent.OE: case
    * SerialPortEvent.FE: case SerialPortEvent.PE: case SerialPortEvent.CD:
    * case SerialPortEvent.CTS: case SerialPortEvent.DSR: case
    * SerialPortEvent.RI: case SerialPortEvent.OUTPUT_BUFFER_EMPTY: break;
    */
    case SerialPortEvent.DATA_AVAILABLE:
    readBuffer = new byte[8];

    try {

    while (inputStream.available()>0) {

    int numBytes = inputStream.read(readBuffer);
    // System.out.println("Number of bytes read " + numBytes);
    }



    System.out.print(new String(readBuffer));

    } catch (IOException e) {
    System.out.println("IO Exception in SerialEvent()");
    }
    break;
    }

    I want to store this output and use the output in another class.
    The byte array holds what was read.
    Provide access to that array to the other class.
    If you don't understand my answer, don't ignore it, ask a question.
