    I have a Digi Acceleport 920 2r card. I got the latest drivers from digi,
    compiled everything, and all seems to compile and install correctly.

    I can bring up the digi monitoring utility, and see RTS/CTS/DSR/DCD/DTR
    turn on and off as connections are made.

    But absolutely no information flows. I've tried this with two different
    cables, with all sorts of baud rates, etc. and I get absolutely nothing.

    I even tried a loopback between the two ports on the card, using a
    null-modem cable, no dice.

    The card should be OK; it worked fine when it was pulled from the old
    machine, so I have no idea why it doesn't work. Unfortunately the old
    machine is gone, so I can't re-test the card.

    I remember on my last go around with digi drivers that they can be
    finicky, so I'm looking for advice or suggestions.

    Any settings I have to make with ditty? Any tests I can run to see if the
    card works?

    I'm running FC2 with a vanilla 2.6.10 driver. I even tried the kernel
    epca driver; it loads but I don't have any of the other utilities
    (digiDload, etc.) so I can't test any further.

    The only indication that something may be wrong is if I enable interrupts
    - I get this in my logs:
