PPP Using a Credit Card

Note: Click on images for an enlarged view.

There are two options recommended when using a credit card in dial-up networking:
  1. Enter the entire dialing sequence including credit card number in the "Phone number" section as shown. In this case, the hotel dialing instructions to get to AT&T would be first, then the number you are calling, then 7-8 commas, and finally the credit card number. The commas are to make the modem pause for a period of time, usually 2 seconds per comma. This causes the modem to wait for the tone signaling you to enter your credit card number. The timing is critical using this method and sometimes you have to adjust the number of commas.
 
  1. Use manual dial. In this case, you actually dial the number on the phone set in the room, listen for the correct tones, enter your credit card number, then allow the computer to connect. This is a more reliable option in most cases. However, it requires that your modem allow a phone set to be connected to it. (The modem must have two ports.) These are the steps.
  1. Set up your dial-up networking icon to use manual dial -
  1. Right click on the icon. Choose "Properties".
 
  1. Click on the "Configure…" button.
 
  1. Choose the "Options" tab. Click on "Operator assisted or manual dial".
  2. Save options by clicking on "OK", then "OK" again.
  1. Connect the line from the wall to your modem, then a line out from your modem to the phone in the room.
  2. Double click on the ISU PPP icon, then click on the first "Connect" button. This is the next screen that you will see.
 
  1. There is a trick at this point in getting the systems to connect.
  1. Manually dial the numbers the hotel gives to get to AT&T.
  2. Dial the end user number.
  3. Wait for the calling card tone. Enter the calling card number except the last digit.
  4. Click the "Connect" box on your computer.
  5. Dial the last digit and hang up the phone.
