PPP connect
This command used to initiate a PPP connection with the active Remote Access configuration.
This same script using Network Setup Scripting would read:
tell application "Network Setup Scripting"
open database
tell Remote Access configuration x to connect
close database
end tell
"Remote Access configuration x" is an existing Remote Access configuration containing the values for user name, phone number, etc. for the connection you wish to make. This script will work for any Remote Access configuration regardless of protocol, so it can be used for either PPP or ARAP connections.
