    SubjectRe: UART support 2.2 + PCMCIA.

    Ok, I've rxed the device and it looks like some driver debugging is
    in order. [This is the brainboxes card btw ,{www.brainboxes.com}]

    The 2.4 behaviour is that it is found by the pcmcia later on
    insertion and allocates/finds its irq + i/o. serail.c
    detects the uart + irq also.

    But in operation no irq's are received, data does come in
    an out the UART _slowly_ , as if serial.c as fallen-back to
    polled operation.
    {Interestingly enough 2.2 wouldn't allocate the irq at all,
    even though my modem works fine! }

    2.4 doesn't see the second port. {Neither does 2.2 but if
    i read the pcmcia code correctly setup is aborted after the
    RequestIRQ() fails}.

    I've got a contact name at the manufacturer I can talk to
    on Monday about getting this sorted, so I will work on the drivers
    then if I can. However in the meantime does anyone know any tricks
    I could play, if I could resurrect the card today I would be v.
    _grateful_.
    I willing to concentrate on 2.4 since I guess that will be the
    path of least resistance, what with correct uart support and
    intergated pcmcia stuff.

    More info, testing etc on request.

    TTFN
