Chat Script Overview
Chat scripts are strings of text used to send commands for modem dialing, logging in to remote systems,
and initializing asynchronous devices connected to an asynchronous line.
Note On a router, chat scripts can be configured only on the auxiliary port.
A chat script must be configured to dial out on asynchronous lines. You also can configure chat scripts
so that they can be executed automatically for other specific events on a line, or so that they are executed
manually.
Each chat script is defined for a different event. These events can include the following:
• Line activation
• Incoming connection initiation
• Asynchronous dial-on-demand routing (DDR)
• Line resets
• Startup
