Hello, please help me, I can't install my modem in my OS ,fedoracore 6.
my modem is Intel V92. I have driver cd, when i read the readme file for
installing modem it tell me copy files in directory but i don't know where i
copy these files :

pctel.tar.gz
ptserial.tar.gz
I created folder in dev , it's name modem , then i copy these files in it,
when i type
ln -s /dev/ttyS15/dev/modem in bash, it tell me ln: accessing '-s':no such
file or directory.
