    Fedora Core 6, added a new serial card, now what?

    We have a Hylafax server going on a Fedora Core 6 installation. We had two modems running on the onboard serial ports just fine. We need to expand our fax lines, so we added a PCI serial port card.

    Now what? I expected to see new serial ports show up in /dev/ttyS*, but there are still the original four (0 and 1 are the current modems, 2 and 3 were there before and I assumed those were the USB ports?). Do I need to do something to "install" the new card in the software, or what? Any help would be greatly appreciated - thanks!!

    Chances are that you need to add the driver. Fedora Core 6 is pretty old, and won't have support for newer hardware.

    Either you find a way to add the drivers, or you update to a newer kernel or newer version of Fedora. I doubt that you want to screw around with a working server, so maybe you can add the drivers.

    To find out the chips that the card is using, use this command, and post the output here.
    You could also find a different card that is supported by your kernel.

    Hrmmm....thanks. I didn't realize FC6 was that old, although I guess the "server" was built about a year and half ago. Actually, it's the desktop version of it, too, on a woefully underpowered PC. I'd really like to redo it in Ubuntu Server since that's what I'm familiar with, but like you said, it's not fun to mess with a working server! I don't think they really put much thought into the card they ordered, as far as I know it's just a generic PCI serial port expansion card.

    Anyway, I'll run that command tomorrow when I get to work and see what it says. Maybe I'll go ahead and run any yum updates, too...I'm sure there's a ton.

    Thanks again!

    Be careful with updates, it can easily break a working system. Especially be careful with kernel updates. You may want to just leave it, and start working on the replacement. Maybe start with a new hard drive, you can install a newer version of Linux on it. This would leave the working version untouched.

    I'll talk things over with the team here and see what they think. So am I correct in thinking that if the new serial ports were detected I would see ttyS4 and S5?

    Hrmmmm....after searching some more on that specific card, it seems like it *may* already be working? I found some other posts that suggest that S2 and S3 are actually the new ports....I'll try hooking up another modem and see if it works!

    I'm not 100% certain, but I think that these are the modules for the card.


    You can check if they are loaded. You can also check the output of dmesg for messages concerning this card and the ports.

    Check out this link that I found
    NetMos 9845CV

    It isn't for your model of card. But it does give a lot of info on how to create the device ports using the setserial command, if they aren't created automatically.

    Thanks all! It turns out the FC6 kernel was 2.6, and apparently it was all working all along. I assumed the S2 and S3 were already there; those are actually the ports for the new card. I hooked up a modem to the card, configured ttyS2 in hylafax, and everything seems to be working great. Thanks for all the help, and I did learn some new things. I still want to rebuild the thing's really slow (prev admin put FC6 desktop version on a Pentium I-266Mhz with 256MB of RAM!)
