Select menu option 1, Configure Dialout PPP, and press Enter to configure the router's Dialout PPP settings. This will open the default Dialout PPP configuration file in your default text editor (your file may look slightly different):
Once you have entered all of the Dialout PPP rules in this file, save the file by pressing Control-X. If you have made changes to the file, the router will prompt you to save the file at the bottom of the screen:
     Save modified buffer (ANSWERING "No" WILL DESTROY CHANGES) ? Y Yes N No	^C Cancel
Press Y to confirm your changes. The router will prompt you for a file name:
     File Name to write: /etc/ppp/dialer_setup ^C Cancel 
You should accept the default filename. If you choose to save the file in a different location, the router will not automatically locate the file and instate any changes. Press Enter on the keyboard to accept the default. The ^C notation indicates the key combination Control-C. You may press Control-C at any time during the save process to return to the file.
Note: You must save the settings to the router's non-volatile flash memory! If the router is rebooted before saving, your changes will be lost! See Chapter 26, "Backup/Restore Menu: Managing Configurations" for more information.
Once you have saved the file by pressing Enter, the router will return you to the Dialout PPP menu:
     Dialout PPP, (stopped)

Enabling Dialout PPP at Boot-time

2. Enable Dialout PPP on boot
Selecting this menu option enables the Dialout PPP configuration when the router is booted. This does not start Dialout PPP on the router if it is not running, unless the router is rebooted first. By default, the Dialout PPP configuration is disabled on boot. To enable Dialout PPP on boot, select this menu option by pressing 2 and Enter. The router will display the following message:
     dialout-ppp enabled on boot. 
If the Dialout PPP configuration has already been enabled on boot, the router will display the message:
     dialout-ppp already enabled on boot. 
The resulting message will only be displayed for a few seconds, and then you will be returned to the Dialout PPP menu.

Disabling Dialout PPP at Boot-time

3. Disable Dialout PPP on boot
Selecting this menu option disables the Dialout PPP rules when the router is booted. This does not stop Dialout PPP on the router if it is running, unless the router is rebooted first. To disable Dialout PPP on boot, select this menu option by pressing 3 and Enter. The router will display the following message:
     Dialout PPP disabled on boot. 
If the dialout PPP configuration has already been disabled on boot, the router will display the message:
     Dialout PPP already disabled on boot. 
The resulting message will only be displayed for a few seconds, and then you will be returned to the Dialout PPP menu

Start Dialout PPP

4. Start Dialout PPP
Selecting this menu option starts the Dialout PPP service on the router. Starting the Dialout PPP configuration does not automatically enable Dialout PPP when the router is booted. To start the Dialout PPP service, select this menu option by pressing 4 and Enter. The router will display the following message:
      Starting Dialout PPP...done. 
The message will only be displayed for a few seconds, and then you will be returned to the Dialout PPP menu.

Stop Dialout PPP

5. Stop Dialout PPP
Selecting this menu option stop the Dialout PPP service on the router. Stopping the Dialout PPP configuration does not automatically disable Dialout PPP when the router is booted. To stop the Dialout PPP service, select this menu option by pressing 4 and Enter. The router will display the following message:
     Stopping Dialout PPP...done. 
The message will only be displayed for a few seconds, and then you will be returned to the Dialout PPP menu.

Viewing Dialer Messages

6. View dialer messages
Selecting this menu option will display any PPP dialer messages stored in the dialer log. If there are no messages in the log, the screen will display:
     No messages. 
Otherwise, the contents of the dialer log will be display using the less program. less allows you to scroll through the contents of the file using the arrow keys. At the bottom of the output, you will see the following message:
     Hit Q to exit. 
Press 'Q' or 'q' on the keyboard to exit the log output and return to the Dialout PPP menu
