    I need to develop a driver for a multifunction PCMCIA card with a standard
    serial interface (16550) and a proprietary FIFO interface. I can access the
    serial port now, but the FIFO is the problem.

    Since I have so far no experience with Kernel driver development, and since
    the application is not very demanding and all this happens in a controlled
    embedded environment (x86 based), I'm tempted to do this in user land if
    possible...

    Any help now at the design stage would be much appreciated, so that I don't
    run into the wrong direction!

    - First of all: is this possible? I need to access a few registers on the
    PCMCIA card and that should be it. No IRQs, I think I can get away with
    polling.

    - Any hints for documentation on how to do it? Does anybody know of any
    similar drivers that already exist?

    Thanks a lot already...

    Wolfgang
