portlist = commportidentifier.getportidentifiers();      while (portlist.hasmoreelements()) {         portid = (commportidentifier) portlist.nextelement();         if (portid.getporttype() == commportidentifier.port_serial) {             if (portid.getname().equals("com9")) {                 try {                     serialport = (serialport)                     portid.open("simplewriteapp", 2000);                 } catch (portinuseexception e) {                     system.out.println("error1 "+ e);                 }                 try {                     outputstream = serialport.getoutputstream();                 } catch (ioexception e) {                     system.out.println("error2 "+ e);                 }                 try {                     serialport.setserialportparams(9600,                         serialport.databits_8,                         serialport.stopbits_1,                         serialport.parity_none);                 } catch (unsupportedcommoperationexception e) {                     system.out.println("error3 "+ e);                 }                 try {                     string number = "1";                     byte arduino[] = number.getbytes();                     for(int i=0; i<arduino.length; i++){                         outputstream.write(arduino[i]);                     }                     outputstream.flush();                 } catch (ioexception e) {                     system.out.println("error is4 "+ e);                 }              }         }     }
