Hi Miklos,
Sorry for my late reply.
i had a chance to try your test code several times, but the leds never
toggled,  which means
ArbiterInfo.inUse() == true, it never turns out to be false!
Then the overall code is the same as in rev1.10. But my network works quite
well !  I did not come accross with any sudden disconnection problem that i
mentioned in my first e-mail. That's so weird, isn't it?
When I use rev.1.9,  the problem occurs again.
Anyhow, i noticed that the new rev.1.11 on the CVS, it seems to work for
now,
Thanks you very much Miklos,
Regards,
