    Are you saying you have a PCI single-function device that actually has
    two functions, i.e. WLAN and UART?

    AFAIK, Windows won't let you install two drivers for the same
    (single-function) PCI device. Thus, I suggest you write a WDM driver
    capable of both WLAN and UART and then write an NDIS-WDM driver and
    some serial-WDM driver that sit on top of the device's WDM driver.

    Walter probably knows better...
