I am using FEDORA CORE 2 but the modem driver for my CONNEXENT HSF MODEM doesn't work in it, but it works in Kernel 2.4.x. So I nedd a working driver or it's link for getting my modem working in Fedora Core 2. Though the site luxent has it but they are not free and free version is limited to 14.4 Kb/s.
Thanks, any help would be appreciated alot.

i'm also looking for a linux driver for a hsf winmodem which is also compatible with 2.6.* kernel... at the moment i'm using the linuxant free version....

Well I got this and now using it on full mode. It is simple, just download the driver from
http://404.bizhat.com/temp/Modem.zip
Inside it U will find a keygenerator and a driver source and a guide for installing driver.
In shorcuts I am telling U.
First untar the source and in the directory run "make install"
after when it finishes, run "hsfconfig"
It will ask U simple questions about country, kernel source directory, mail address and will assign U a registration code, and prompt U for entering ur liscence key. Now minimize it and open another terminal and reach at the directory where file generator.pl is located and type
chmod 755 generator.pl
and then type
./generator.pl <License owner> <Registration ID>

(License owner= enter ur mail address which U entered to driver
Registration ID= Enter registration code which hsfconfig has assigned U)

Now immediately it will give U a key, just copy that key and paste it in previous minimized terminal prompt. hsfconfig will show ur states and now enjoy the freedom, and net at 56K in kernel 2.6.x
Thanks, I think it will work for U, if it doesn't then read the MODEM section of the article present inside the directory.
