    Is it possible to setup programmatically Fifo buffers ( ForceFifoEnable/
    TxFIFO/RxFIFO) without reboot ?
    I wrote to registry what I need and tried devcon to do the job but result
    below :
    C:\>DEVCON RESTART @AcPI\pnp0501\1
    ACPI\PNP0501\1 : Requires
    reboot
    Not all of 1 device(s) restarted, at least one requires reboot to complete
    the o
    peration.
    TIA

  2. does some app have the com port open? if so, that app needs to register for
    file handle notifications and close its handle while the stack is being
    restarted.
