did you look in device manager to see what the conflict was?
IE do you have two com 1's ?  Or is the interupt shared?
are you useing fax software that is siezing the device?

You want help - then help yourself, by describing the problem --- in detail ---
you have posted three times and have yet to tell us what OS this is for
2k? XP? 2K3? Vista?
did you use DriverPacks?
If so waht packs and Base version
is this a clean load. did the device come with the machine
what type of machine. other software running.

We are not mind readers...

this is like a drunk calling for a cab and then hanging up before giving the cabbie the address.

we do not find drivers for people nor do we repair PC's on this forum.
we provide bulk drivers. if you find that a driver is not in the pack it is up to you to find and report that driver.
If a driver fails to install it is up to you to discover why.  (we don't have one of your modems to play with)
if you wish to share your fix please do.

if you just want free tech support (my guess at this point) at least provide a decent description of the problem.
and act like you know the divverence between a modem and your shoe.

You can get help here - we often do go beyond the scope of the forum
but you must at least give a good description.
had you not said please and thank you i would have deleted this topic already.

this is the log after installing that driver.

i found the driver in the folder "C\8" driver name is conexant D850 56K V.9x DFVc Modem. can any1 please tell me how to resolve this problem?

Was the machine installed with third party DriverPacks for modem slipstreamed into XP?
