  1. Select the Windows Start button, then the Settings menu, and then the Control Panel from the Settings menu.
  2. Double click on the Network icon.
  3. Click Add and then select the Protocol option from the browse box and click Add.

  9. In the IP Address field type in the IP Address ( e.g. "" - 192.168.2.* is a fixed local address in terms of IP addressing, so you can use the last digit to set the unique IP address of each local user), and in the Subnet Mask field enter the mask "". Note: Each user must have a unique IP Address.
  10. Click the OK button.

Important: You do not have to have a network card or be on a network to make CovertCall work, as long as at least one TCP/IP adapter is setup. An adapter is a physical device like a Network card or a Modem. If you don't have a modem or a Network Card in your computer. You can still add a Modem in your Network settings even though it's not present. (CovertCall works when a TCP/IP modem adapter is setup in the Network properties even if the Modem is not plugged into the machine or connected to the Internet.)

How to check if TCP/IP is installed on your computer

To check if your computer has TCP/IP installed you can do the following:
  1. Select the Windows Start button, then the Settings menu, and then the Control Panel from the Settings menu.
  2. Double click on the Network icon.
  3. Look in the top list box in the Configuration tab.
  4. If you do not see an entry that starts with TCP/IP then you have not installed TCP/IP. You can install it using the How to add TCP/IP instructions.
If TCP/IP is installed on your computer and you still cannot see anybody in your CovertCall  "Computers online" list, then it might be the case that you have a personal firewall installed on your computer. You need to make sure that the firewall has been configured so that the following ports are available for CovertCall to use:

UDP port number (streamed port):       2230

TCP/IP port number (datagram port):    2240
