[Rxtx] Underlying input stream returned zero bytes

[TEIXOEIRA at terra.es]

Hi, there.
I'm having difficulties reading a serial line with RXTX 2.1-7 on Windows XP, I can communicate through this serial line using 
HiperTerminal though.
Also, I can't find any clues about this issue on the internet. Can anybody tell what might cause this exception while reading?

Kind regards.
