Need help installing and connecting wvdial

Hello. I am new to linux. I cannot seem to connect to the internet. I have mandriva le 2005. I have a winmodem. Smartlink SmartPCI562 56k modem (revlo)

I tried to connect using kppp but screen would freeze on 'initialising modem'.

I then got wvdial-1.54.0-3mdk.i586.rpm Tried to install it using command line after reading instructions but with no success. Keep getting 'error no such command' or something like that.

Then I read that I needed a driver for my modem. I downloaded one form here smlinkdotcom
Got it on my linux box but after reading the 'readme' I still am clueless on how to install the driver.

Anyway after failing to get the command line to work, (my fault I don't have any exp with cli) I clicked on the wvdial-1.54.0-3mdk.i586.rpm icon. It was in a folder I named 'cdstuff' After clicking install i got an error message.
It read 'some package requested can not be installed wvdial-1.54.0-3mdk.i586 (due to unsatisfied libwvstreams.so.3.74 continue?)

I clicked continue and it said package installed. However I do not know whever it is installed or not and if it is how to run it. Again no luck with command lines I got off google.

Now I go to google and download wvstreams-3.74-61.i586.rpm
I have it on a cd and am going to put it on my linux box. However regarding previous problems I've had I am thinking I will have problem with this as well so is their any trick to installing it?

Would anyone out there be able to help me with this?
Thanks for your time

I have got wvdial installed. Did a google for wvstreams-3.74-61.i586.rpm and tranferred it to my linux box with a cd-rw. Clicked on the icon and it installed. Then clicked on the wvdial icon and this time it installed properly. Then went to konsole/command line. Typed 'wvdial' and pressed enter. Loads up but won't detect my linmodem/winmodem.
Thanks for your time and help.
