Invoking the Chat Script

You call chat scripts by using the connect option. You can use connect "chat ..." in any PPP configuration file or on the command line.

Chat scripts are not executable, but the program that is invoked by connect must be executable. If you use the chat utility as that program and store your chat script in an external file by using the -f option, then your chat script file is not executable.

The chat program that is described in chat(1m) executes the actual chat script. The pppd daemon invokes the chat program whenever pppd encounters the connect "chat ..." option.

You can use any external program, such as Perl or Tcl, to create advanced chat scripts. Solaris PPP 4.0 provides the chat utility as a convenience.
