Hi,
  Thank you for the message David . It is exactly what
I was asking for, too bad you can't share the
application. 
  One question though:  The Java API for the USB
connections is not outstanding, I use win2000 + cygwin
as OS. I tried the jsr-80 API and I get a lot of
erros. What API did you use, and what was the OS ?

Thanks,
Gelu
