Before the dial-out machine can initiate a PPP link, you must collect information about the dial-in server that is to become the peer. Then, you use this information to create the chat script, which describes the actual conversation between the dial-out machine and the peer.
Determine the speed at which the dial-out machine's modem needs to run.
For more information, see Configuring Modem Speed for a Dial-up Link.
Obtain the following information from the dial-in server's site.
Server's telephone number
Authentication protocol that is used, if appropriate
Login sequence that is required by the peer for the chat script
Obtain the names and IP addresses of name servers at the dial-in server's site.
In a chat script, provide instructions for initiating calls to the particular peer.

The script contains instructions for calling a Solaris dial-in server that requires a login sequence. For a description of each instruction, refer to Basic Chat Script Enhanced for a UNIX-Style Login. For complete details about creating a chat script, read the section Defining the Conversation on the Dial-up Link.
You do not invoke the chat script directly. Rather, you use the file name of the chat script as an argument to the chat command, which invokes the script.
If a peer runs Solaris or a similar operating system, consider using the previous chat script as a template for your dial-out machines.
