It seems I have run into a bit of a roadblock. It appears that the C-201 will only speak, through it's 16550 UART, at a speed of 230400. As such it need to have fast interrupt support, which only seems possible with a dedicated interrupt. ACPI and NEWCARD assigns the same interrupt to both of the Cardbus bridges and to other PCI devices. Any suggestions how I might accomplish the assignment of a dedicated interrupt? BTW, this device does work under Linux, Windows 2000, and Windows 98SE.
