Modem Sagem fast 800

Hello, pardon by my ingles, I am Spanish, and I do not develop very well with this language.

 

I have installed winXP professional x64, everything, fast works to me correctly and very stable.

 

Everything correctly with exception of modem ADSL has settled, one is a Sagem F@st 800, I have proven drivers for winXP, and I have even unloaded I complete them available in its Web. But all of them gives errors me, and I cannot form it, in winXP professional it works perfectly, now me I grasp them to connect to me to Internet, thanks to router that they have rendered to me.

There is some form to be able to make work it?,  with driver nonofficial, or modifying a file?

Thank you very much.

The only voice modem that works in Win XP64 is with the Intel chipset 536 or 537, my got 537EP, you can download the driver from Intel, but you may have software problem, the software faxtalk 4.5 does not work in win xp64.
