This sounds like a problem I have with the AST-FourPort/XN card;
in particular, I have a device hooked up to one port which uses
XON/XOFF protocol.  Sometimes, however, I don't get complete reads
from the port -- just as though it had XOFF'ed, but I didn't see it.
I've also had problems with enabling ports and then watching ALL
i/o on ALL of the card's ports hang permanently until I reboot.

Does this sound familiar to anyone else?
