Open Transport


If you have MacOS 8.0 or higher, Open Transport should be built into your operating system. (It is possible that MacOS 7.5 or 7.6 may have it installed, as well). Open Transport is Apple’s latest software and it supercedes MacTCP, and MacPPP. FreePPP will work with Open Transport, but it is unnecessary since OT includes a PPP Control Panel (renamed Remote Access since 8.5).

Configuring Open Transport

Configuring Open Transport is as simple as entering the proper information into each of 3 Control Panels: PPP, Modem, and TCP/IP. In all cases, "Save Changes" when prompted when closing the control panels. All control panels can be accessed via the Control Panels folder under the Apple Menu.

The OT Control Panels



Select Registered User.

Enter your username and password that you selected when you set up your account over the phone with the NetCarrier representative.

Note that usually, letters are in lower case and no spaces are present.

Enter the NetCarrier phone number that your computer will be dialing. This depends upon your location and account type, and will be provided by your NetCarrier rep.

Click "Options..."

2. Complete as shown.

3. Complete as shown.

4. Complete as shown.

If the modem gives us difficulty connecting, we may choose to disable the two check boxes and try again.


Complete as shown.

For Modem, you must choose an installed Modem Script that CORRESPONDS TO YOUR PARTICULAR MODEM. This is the area with greatest potential for difficulty.

a) You can usually tell the Manufacturer/Model of your modem either from how the modem is labeled, the packing list that came with your computer, or else the manual that accompanied the modem.

b) Based on this info, choose the Modem script from the pop-up menu that best matches your modem.

c) If there is none that matches, try one that exists that is "close", such as the same Manufacturer or modem speed, to see if it will work at all.

d) If nothing works, NetCarrier may be able to locate a suitable script for you on the internet. Or, you may have to phone the modem’s manufacturer for the appropriate script.

Finally, if the phone line from which your computer will be dialing has PULSE service (rather than Dial Tone), choose "Pulse" and check "Ignore Dial Tone".

Close the Modem control panel.


Complete as shown.

Close the TCP/IP control panel.

7. Return to the PPP Control Panel.

Click "Connect".

If all has been set up properly and your modem is properly connected, you will be able to watch the Status area and listen to the modem as it logs on and eventually displays as Status similar to that shown on the right.

Congratulations! You're on the Internet!

Of couse, to do anything, you now need to run an Internet application such as Email (Eudora) or Web Browsing (Internet Explorer), both described elsewhere in this manual.

Have fun!
