The device interrupted (although device interrupts are supposed to be disabled) before any of the ports were opened. Probably after they were configured. The message should go away after the ports have been opened at least ones. The driver won't know what to do with the interrupts, but it will know they aren't for it, and it will quietly ignore them. Try dummy opens (stty -f /dev/ttyd[0-9]). >After having removed the reference to IRQ 7 on the lpt line I am >getting lots of stray IRQ7 messages. Does this mean that the card is >generatingIRQ's even with nothing connected to it and the OS does not >know what to do with them? This can be caused by garbage signals on any IRQ line. Perhaps it is caused by the same things as the extra serial interrupts. Using IRQ7 for the lpt hides the problem. Bruce
