the part that bothers me (and i dont have the programmer's guide for
the solos hardware) is that you are watching for the PKT_PCLOSE to be
sent to the card. shouldnt you be watching for the PKT_PCLOSE to be
returned from the card (assuming it does such a thing) so that you can
be assured that the tx/rx for this vpi/vci pair has been "stopped"?
