TCP Overview:

Links on this page:  Open TCP | Manage Configurations | Check TCP settings |

TCP is used by any program that does anything on the internet.  TCP lets your computer programs communicate through your modem.  It is used by Internet Explorer to access websites.  It is used by Outlook Express to send and receive e-mail.  It is used by Fetch to transfer files quickly over the Internet.


Opening TCP:

There are two common ways to open TCP.  The easier way is shown first.

Open TCP while in PPP (or RemoteAccess, Free PPP, etc.):

If you're already configuring PPP, you can open TCP easily.

With PPP open, click PPP on the toolbar, then TCP/IP, as shown below.

                (For PPP, it would be the PPP menu rather than the PPP menu.)

Or, open TCP through the Control Panel:

To open TCP, click the Apple, then Control Panels, and finally TCP, as shown below.

Note:  If TCP isn't listed, it's probably not enabled in the Extensions Manager
          Click here for help.

The TCP configuration dialogue opens, as shown below.


Remove old/outdated configurations & Make yours Active:

Before taking time to check your settings, make sure you are looking at the settings for the right ISP.

With TCP open, click on File, then Configurations, as shown below.


The Configurations dialogue box opens, as shown below.

First, delete any TCP configurations not in use.  You wouldn't want to inadvertently your old ISP's settings.

You can have more than one TCP "Configuration" for PPP.  There are several reasons you may want to do this:

  1. Different members of the same household my be using different ISP's to connect to the Internet.

  2. You use your laptop at work on an Ethernet LAN and at home on a Modem PPP Dialup.

In both cases, you would need to come to this screen to Make Active whichever TCP Configuration you require at the moment.

If you use your computer strictly for modem dial-up access, delete all the other configurations, leaving only one.

When you've finished, click the Done button to return to the main TCP screen, shown below.


Configure TCP for dial-up:

Here is the main screen of TCP.

Notice across the top that the name of your Active Configuration is shown in parentheses.  If you had made "OtherCity" the Active Configuration, then (OtherCity) would be listed in place of (ISPName).

Tip: Can't make changes? Fields grayed out?  You may need to be in Administrator mode. 
      Click Edit, then User Mode, then select Administrator.  Click here for screenshots.


The two fields at the top determine how TCP acts on your computer.

Connect via = Choose PPP for a dial-up modem connection.  This makes TCP work with PPP.
                     = Choose Ethernet if you are connecting to a LAN at work or to DSL/Cable at home.

Configure = Choose Using PPP Server for a dial-up modem connection.  This makes TCP work with PPP.
                  = Choose DHCP Server for typical LAN or DSL/Cable setups.

Name server addr = and


Click the Options button for some extra settings.

There should be a dot in front of Active, and a checkmark for Load only when needed.

Click OK when you've finished.

Then close TCP to complete the configuration.
