boot messages: ttyS00 at 0x03f8 (irq = 4) is a 16550A ttyS01 at 0x02f8 (irq = 3) is a 16550A ttyS02 at 0x03e8 (irq = 4) is a 16550A so it's completely useless, it just sets it to 'standard' values, I have to manually set it to proper IRQ (I put a line into /etc/serial.conf) /proc/interrupts: the same, it just shows whatever I set. AFAIK it only shows actually received interrupts, so unless I really use the modem it wouldn't show anything, and to use modem I need to know interrupts. isn't there a way to find that out? I don't know how windows do it but they are able to figure it out somehow. erik
