To install PCI hardware modem
enter as a root
write # cat /proc/pci
you will find something like that
Bus 0, device 10, function 0: Communication controller: PCI device 151f:0000 (TOPIC SEMICONDUCTOR Corp) (rev 0).IRQ 12. I/O at 0xbc00 [0xbc07].
Now, you should have this command “setserial” if you don’t have it search the internet and download it
look carefully to the IRQ and I/O
Write :
setserial /dev/ttyS3 uart 16550A port 0xbc00 irq 12
You can use any other ttyS? device as well
then try to make connection using kppp for example if it is work then
Make sure that the setserial command is issued each time upon the boot-up, making a necessary addition somewhere in /etc/init.d/ or /etc/rc.d/, depending upon your distribution.
