Peace!

I have a motorola sm56 softmodem. I got their new driver for RH 9.0 from www.motorola.com/softmodem/ and I installed it correctly without any error messages. It even said it was a successful installation.
I can't make my modem work!
It keeps giving me modem is busy when I do a query modem from kppp (as root).
I have tried all ttySx and I keep getting this error. But for the other /dev/modem I get modem is not found.

How may I make it work? And could anyone here make it work for RH 9.0?
