Trouble getting reader to return text using readByte() #83

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
very new to serial programming and to Java so please excuse me if the question 
is simple.

What steps will reproduce the problem?
1. the serial port code:

public void serialEvent(SerialPortEvent event) {
            System.out.println(event.getEventValue());
            if(event.isRXCHAR()){//If data is available
                if(event.getEventValue() == 5){//Check bytes count in the input buffer
                    //Read data, if 10 bytes available
                    try {
                        byte[] buffer = serialPort.readBytes(10);
                        System.out.println(buffer);
                        cps.write(buffer);
                    }
                    catch (SerialPortException ex) {
                        System.out.println(ex + "what happened here?");
                    } catch (IOException ex) {
                        Logger.getLogger(Simple.class.getName()).log(Level.SEVERE, null, ex);
                    }
                }
            }
           else if(event.isCTS()){//If CTS line has changed state
                if(event.getEventValue() == 1){//If line is ON
                    System.out.println("CTS - ON");
                }
                else {
                    System.out.println("CTS - OFF");
                }
            }
            else if(event.isDSR()){///If DSR line has changed state
                if(event.getEventValue() == 1){//If line is ON
                    System.out.println("DSR - ON");
                }
                else {
                    System.out.println("DSR - OFF");
                }
            }

        } 
    }

2.  I the Output of this code only appears to be the index of the items.  If I 
send characters through 232 port regardless of what I send the out put is '1' 
then '2' then '3' etc.  when it gets to '5' (10 bytes?) it seems to shutdown.  
the IDM directs me to the line with the readBytes(10).

3. I am hoping to take text input from this 232 connection and display it, so 
for only index numbers an only 5 of those.

What version of the product are you using? On what operating system?
Jssc 2.6
Product Version: NetBeans IDE 8.0 (Build 201403101706)

Thanks in advance!

IDE not IDM, sorry for the type-o
