I have read posts and checked websites for a while now, and have gotten no where really. i have an intel 5346ep modem, i went to Intel's site downlaoded the Fedora Core 1 file intel536-4.68-fc1-up.tgz. i rebooted into linux, decompressed the file, ran the commands, make clean, make 536, make install like the readme said, all worked with no errors. now i tried to use the network connection wizard, it probes for modems but finds none. so i check to see if my 536ep modules are loaded, they are, i check /etc/sysconfig/hwconf, it shows this:

class: MODEM
bus: PCI
detached: 0
driver: unknown
desc: "Intel Corp.|536EP Data Fax Modem"
vendorId: 8086
deviceId: 1040
subVendorId: 8086
subDeviceId: 1000
pciType: 1
pcibus: 2
pcidev: a
pcifn: 0
-
class: MODEM
bus: PCI
detached: 0
driver: unknown
desc: "U.S. Robotics|unknown device 16ec:2f00"
vendorId: 16ec
deviceId: 2f00
subVendorId: 16ec
subDeviceId: 010a
pciType: 1
pcibus: 2
pcidev: b
pcifn: 0

Now I'm not even trying to work with the U.S.R, modem thats just useless and i have tried removing the U.S.R. modem to see if linux was just "confused" by it, but no. The only idea i have at the moment is to change the hwconf file to list the driver for the Intel Corp.|536EP Data Fax Modem. Problem is i don't know the file name or default location for sure. I was hoping someone here might no where it is located or could steer my in the direction of another solution. thanks guys.

i think first, you could remove the robotics modem. then reboot.
then rerun the configuration utility for your intel modem. not sure which command to use.
then it will tell you which device is it at , which will be something looks like /dev/tty8.

also, could you post the output of "/etc/modules.conf", it will be helpful to tell you what to do

ok i removed the U.S.R. modem and reran the configuration utility and still nothing, you wanted my modules.conf so here it is:

alias eth0 via-rhine
alias scsi_hostadapter ata_piix
alias usb-controller usb-uhci
alias usb-controller1 ehci-hcd
alias ieee1394-controller ohci1394
alias sound-slot-0 i810_audio
alias sound-slot-1 audigy
post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1 || :
pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 || :
post-install sound-slot-1 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1 || :
pre-remove sound-slot-1 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 || :

then the only thing i would do would be reinstall the driver and see what happens.
just making sure, it's there any error in "dmesg"?
