Comment on Tutorial : Read from a COM port using Java program By Steven Lim
Hi Johnny,

did you check whether the settings for the COM port are correct? i.e. if

serialPort.setSerialPortParams(9600,
SerialPort.DATABITS_8,
SerialPort.STOPBITS_1,
SerialPort.PARITY_NONE);

matches the settings of your barcode scanner / modem / <insert arbitrary device here> ?

Kind regards
Frank
