Ok.... another question :) : "Who" decides which card will re-transmit its
data first? (I think it will be the card that was first using the line,
but....)
(I think that because if it were not like that, the card that was receiving
the data would have to "be informed" that now the card that is sending
information is not the same that the one that has been doing it...)

I really thank you for your exellent explanation...
And just to finish this message :) :
How does a card know where does the information come from (from which
card)?
And how can a card send information to one card and not to the others?
Thank you very much, and have Merry Christmas and a happy New Year!! :)
