InterPPP uses connection documents to record the information it needs to connect to a remote network. Once a connection document is configured and saved, you can double-click the connection document icon and it automatically launches InterPPP. InterPPP is now ready to connect using its preset parameters. See Chapters 3, 4, and 5 for more information on configuration.
InterPPP uses the Connection Control Language, or CCL , to write modem scripts. Each different type of modem requires a modem script to send commands from your Macintosh to the modem. The commands sent to the modem are used to configure and connect the modems.
Most modem manufacturers provide scripts on the installation disks included with their modem. The CCL scripts in InterPPP are simple text files designed to dial and answer a particular modem. The documents can be copied from machine to machine and can be printed. For more information on CCL scripts, see Appendix B, CCL Scripts.
6.1 Using Connection Documents
to Connect to Remote Networks
InterPPP uses the configuration information in connection documents to connect to specified remote networks. Once a connection document is configured and saved (see Chapter 4, Configuring a Connection
Document ) , you can double-click the connection document icon. This automatically launches InterPPP, which is then ready to connect using its previously configured parameters.
  If you implemented the Dial on Demand feature of InterPPP, your
connection document is located in your Startup Items folder.
 You can only make successful connections if all appropriate
connections are already configured for this document. See Chapters
3, 4, and 5 for information on configuring a connection document
for successful connections.
To open an existing connection document and connect to a remote network:
1. Select Open Connection… from the File menu and choose the
previously configured connection document you want to open from
Apple’s standard Open File dialog.
OR
Double-click the icon of a previously configured InterPPP Connection
Document.
‚àö The selected document opens (Figure 6.1).
 
Figure 6.1 A Configured Connection Document
2. Click Connect to establish a connection to the remote network.
‚àö Status messages are displayed during a connection in the right side of
the Connection Document window (Figure 6.2).
 
Figure 6.2 The Status Displayed in the Connection Document Window
3. If it is necessary to drop your modem’s connection at this point, click
Disconnect.
  InterPPP uses the preferences you configured in the Modem
Configuration dialog to determine what action is taken after your
modem connects to the remote network. See Section 5.1, Modem
Configuration , for more information on available preferences.
6.2 The Status Window
To display more detailed status information during a connection:
1. Select Open Connection… from the File menu and choose the
previously configured connection document you want to open from
Apple’s standard Open File dialog.
OR
Double-click the icon of a previously configured InterPPP connection
document.
‚àö The selected document opens.
2. Click Connect to establish a connection to the remote network.
3. Select Status… from the Status menu.
‚àö The Status window opens (Figure 6.3) and displays the status and
progress of your connection.
 
Figure 6.3 The Status Window
  If the percentage of bad frames in or bad frames out in the Status
window is more than 10% of your frames in or frames out, have
your System Administrator check your modem for problems.
4. If it is necessary to drop your modem’s connection at this point, click
Disconnect in the Status window.
5. Click the close box to close the Status window.
6.3 Your Activity Log
Your Activity Log is a file that InterPPP generates to record the history of each connection InterPPP makes until the next time your Macintosh is restarted. The information in the log is useful, for example, to determine where a connection failed or how certain configuration parameters, such as timeouts, affect your connection.
To view the contents of the Activity Log:
1. Select Activity Log… from the Status menu to view the Activity Log
window anytime your connection document is open.
‚àö The Activity Log window opens (Figure 6.4) and displays information
on the connections you have made with InterPPP.
 
Figure 6.4 The Activity Log Window
2. Use the size box to adjust the window’s size and the scroll bars to view
text that does not fit in the window.
3. Select Print… from the File menu if you want to print the contents of
this Activity Log.
4. Select Save from the File menu if you want to save the contents of this
Activity Log.
  If you do not save your Activity Log, the information in the log is
erased the next time your Macintosh is restarted.
5. Click the close box to close the Activity Log window.
6.4 AppleTalk Status
To monitor the AppleTalk status of an active InterPPP connection:
  AppleTalk routing must be available for your AppleTalk PPP
connection to work. Contact your System Administrator to
determine if your server routes AppleTalk.
1. Open a previously configured connection document and click Connect
in the Connection Document window to connect to the remote
network.
2. Select AppleTalk… from the Configure menu.
‚àö The AppleTalk Status window appears (Figure 6.5) and displays
information about your address, zone, and server.
 
Figure 6.5 The AppleTalk Status Window
3. Click the close box to close the dialog.
‚àö The Connection Document window is displayed.
6.5 Using CCL Scripts
The Connection Control Language, or CCL , is the language used to write modem scripts. Each different type of modem requires a modem script to send commands from the Macintosh to the modem.
CCL scripts are usually provided by your modem vendor. Check your modem installation disks for the CCL script that you need. InterPPP provides default scripts, stored in the Extensions folder, for generic modem types. If, for some reason, you need to create or modify a CCL script, see Appendix B, CCL Scripts, for more information.
The CCL scripts in InterPPP are text files designed to dial and answer particular modems. The scripts can be exchanged between machines, as well as printed.
  Most InterPPP users never have a need to open, print, modify, or
create CCL scripts since modems usually provide their own default
scripts. Information in this manual regarding CCL scripts is
provided for users who are interested in working with scripts.
6.6 Opening CCL Scripts
To open an existing CCL script:
1. Select Open CCL Script… from the File menu.
√ Apple’s standard Open File dialog (Figure 6.6) is displayed, allowing
you to select a CCL script to open.
 
Figure 6.6 Apple’s Standard Open File Dialog
2. Select a CCL script and click Open. (Or click Cancel to close the dialog
without opening a CCL script.)
‚àö The CCL script opens (Figure 6.7).
 
Figure 6.7 An Example of an Open CCL Script
6.7 Creating and Modifying CCL Scripts
InterPPP provides default scripts for generic modems. There usually should be no need to edit these scripts. However, if it is necessary to create or edit a script, follow the procedures in Appendix B, CCL Scripts, as well as the information in the AppleTalk Remote Access Modem Developer’s Guide. This is only suggested for users who are familiar with working with CCL scripts and the particular modem they are using.
