Yes. When I do auto IRQ with setserial, it returns something like: IRQ -1023128419585
Since I only have 15 IRQ's on my machine, and since some of them are taken, and none negative - I'd say that setserial autodetection doesn't work right. My modem is on IRQ, which nothing else is conflicting with. Windows 95 gets the IRQ right without asking, it is not a winmodem.
I haven't tried the kernel level autoirq yet... I will though soon...
Take care, TTYL
