Hi,

I wrote a program in Java to read external device's data thought
serial port. If the external device turn on after the pc booted up,
the program can get data from the serial port. But If the device is
turned on with the pc together, then the program can't get data from
the device. This program and the device can run well at windows. I am
not sure if it is OS issue or program issue. This is over my limited
knowledge. Welcome to any idea. Thanks in advance.
