Depending on the version of Mac OS you're running, you may see some additional fields on the upper-right side of the window as shown in the example above. No further entries are required. Close the dialog box by clicking in the upper-left corner or by choosing Quit in the File menu. When prompted whether to keep the changes, click on the Save button. Restart your computer; the new settings will not take effect until you do this.

Check your modem configuration:
To check values set for your modem connection, click on the Apple in the upper-left corner of your screen and select Control Panels and then Modem. A dialog box appears.

Indicate which port your modem is plugged into (the modem port or the printer port) or whether it is a built-in modem. Next select the type of modem you have from the Setup popup menu. It is very important that the system know what kind of modem it has. Finally, indicate whether you want sound on or off and also whether you're using tone or pulse dialing. Close the dialog box and then click on the Save button to keep any changes you've made.

Create a Remote Access or PPP profile:
If you're running Mac OS 8.5 or later, select Control Panels and then Remote Access (for versions of Mac OS lower than 8.5), choose PPP instead of Remote Access). A dialog box appears.

The dialog boxes for Remote Access and PPP are almost identical, so regardless which you're using, follow the instructions below. First click on the Options button to set the preferences you would like to use.
