FreePPP is a freeware utility that allows you to dial into the Internet, typically known as a "Dialer". Once FreePPP is installed you will have a telephone icon next to the clock in the top right hand corner of your screen.
Click and hold this icon with your mouse and choose "FreePPP Setup"
When you open the FreePPP setup you will be presented with a screen like the one shown below. Click the blue triangle below the FreePPP icon, next to to "Using Generic Modem" you will then be presented with a window that is like that below.
Click the blue arrow shown in the the above diagram to make the window larger and so you can see all the options available. After clicking the triangle your FreePPP window should look like the one below.
When presented with the window above click on the "Accounts" tab. Select the "Untitled" accounts and click "Edit" (Note: That in our window the name is already Saferinternet, not Untitled).
Once you have clicked "Edit" you will be presented with the window below. Fill in the boxes to match those you can see below, replacing with your own Saferinternet username.
After filling in all the boxes under the "Accounts" tab you will then need to click on the "Dialup" tab and fill in the dialup number for your account type. Then click on the "Options" tab and fill it out as indicated below.
This completes the dialup settings. Simply click "Ok" and then click the "Connect" button.
