[newbie] Serial IRQ problem

[Caglar ERGUN]

Hi,   I installed Mandrake 8.0 but I have a problem with the serial port (modem).   It is a isa NON-PNP modem. I set it com3 Irq5 but Linux sees it as Irq 4.   when I enter : setserial /dev/ttyS2 Irg 5 autoconfig ^auto_irq   everything is okay. But when I reboot I loose the setting.   I tried to write a script in a text editor, (assuming as a batch file) containing the above line and made it eXecutable but nothing changed. I both named setserial.conf and lc.d and some other names.   What should I do ?   Another thing is I can't connect to my ISP kind of protocol problem but it is an other issu and I haven't RTFM enough yet :)   Thanks in advance.
