This article will explain:
http://www.56k.com/reports/winmodem.shtml
Also this site:
http://linmodems.org/
Has a tool for detecting the chipset.
I'm working on the assumption that it's a MDV92XP but would like confirmation.

Sorry for the delay, here's what I found:

Your modem apparently uses a smartlimk chipset. However, the smartlink drivers won't work out of the box:

http://www.modemsite.com/56k/smartlink.asp

Has a modified driver that supposedly works (the one with debug.tar.gz extension)

http://www.smlink.com/main/down/linux_instructions.txt

Has the instruction installation sheet.

Finally, this thread:

http://www.linuxforum.com/forums/ind...showtopic=6054

Is a walkthrough of a successful installation (please read entire thread)
Some of it is in Spanish, but none of the critical elements are.

Can't determine wether any of this will work for you, but it might be worth a try.
Please post results (I would suggest doing a backup and creating a rescue or boot disk just in case)

Good luck

u'll be sorry to here this but i found modem setup to be too complicated in linux so i uninstalled it and continued working in my Windows XP SP1

i did stop by to hit u'r afero button and gave you a (very valuable) grade

so mutch from me, bye all
