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.
