Serial com problem (Java)

[dianacgil]

I'm trying to communicate a pc with a Nios development board. From the pc, I'm working with Java, but I have a problem: I don't know how many bytes the information I want to receive from board has... Do I have to use event listeners? How to do it? :roll:
Thanks in advance.
