Have you got another serial card with two serial ports? If not, i think you should have only S0 and S1: /dev/ttyS0 uart 16550A port 0x03f8 irq4 baud_base 115200 spd_normal skip_test /dev/ttyS1 uart 16550A port 0x02f8 irq4 baud_base 115200 spd_normal skip_test You'll probably need an external modem to work instead of a pci winmodem. > f) lspci -v shows the modem there with the right IRQ > g) still can't talk to the serial port > > So, my question is: what am I missing?
