how to set up a zoom usb modem

I don't have access to ANY high speed internet and am solely on dial-up. New computers do not have an internal modem and I had to purchase a Zoom Modem 56k v.92/v.90 for my 13" macbook pro. Can't get it to work.

I went to the Apple store and was informed that Apple does not make modems anymore since "everyone" has high speed internet now.---- well evidently everyone but me. Got a Zoom modem.

Now, how do I get it to work? The place where I purchased the computer does not have a dial-up area where they can help me get it working.

I plugged it in, filled out the information and it doesn't work. Cannot connect. I need step by step instructions for the techie impaired.

Just to register with Apple and write this I have to sit a Dennys' Restaurant where there's wifi.
