I add some detail to my question. I receive on my Xbee device a flow of GPS coordinates but I'm unable to read and stock these data on a buffer.
My Xbee device is connected to my laptop on a usb serial port, that's why I want to create a program java to read and use my data flow sending by the serial port.
I'm searching on internet some code example or tutorials , without enought advices for my understanding, or I just find some dead projects.
I found that it's possible to use jssc library or javax.comm (but I can't download the javax.zip on sun). Do you know an other better USB API ? Could you help me to understand how I can manage to read and stock my Flow of GPS cordinate ?
