I am trying to set up my internet connection. I got this message when I set up kppp dilaler: Sorry the modem is busy. Actually my modem was not in use then. I am using Zoom PCI faxmodem, and my linux system is redhat7.2. I heard Redhat7.2 could
set up modem automatically. I used "cat /proc/pci" command to find starting I/O range and IRQ # for the modem, and used "setserial" command to
set staring address and irq for it. But I got the following error msg: cannot set serial info: Address already in use. I found USB controller and PCI bus were using the same irp # as modem, so I disabled USB controller and PCI IDE master in BIOS, but that did not work either. I am wondering what the main reason is. Thanks.

Do a search here for zoom and see if you can spot the one you have.

The company, that makes this modem, provides reference book to set it up on linux systems. It claims its not a winmodem. I am wondering if any guru here can help me out.

It seems like nobody can figure out these things. No wonder Linux cannot surpass Windows cuz it is not user-friendly, it takes forever to fix these darn things! I guess I have to dump linux part since it cannot get me online.

Nobody can help you unless you post the required info, just telling up what the vendor calls it and that they claim it will work is not enough. We need to know what chip this modem uses in order to help and you need to provide us with that info. If you'd answered my previous post with the details from the link then you might be getting somewhere now instead of throwing a tantrum.
