network programming - Reading data from serial port in java -

i want read data (which weight ) weigh bridge connected computer com1 port. search web , able connect port , read data problem data not meaning full.

i getting below

there weight of 145 on weigh bridge getting these symbols. here code reading data.

hyper terminal reads correct data.

after understand code, maybe can modify code this:

case serialportevent.data_available:             try {                  string inputline=br.readline();                  system.out.println(inputline);             } catch (exception ex) {                 system.err.println(e.tostring());             }              break; 

and move 2 line below port.setserialportparams:

        inputstream = port.getinputstream();         br = new bufferedreader(new inputstreamreader(inputstream));
