        This chapter describes how to configure &TC;; to provide some

        Internet services through the telephone line. In this chapter,

        the computer holding the Internet services is named the

        <quote>server</quote> and the computer that want to make use

        of such services is named the <quote>client</quote>. We assume

        that both server and client computers have been installed with

        &TC;; (release 5.5).

        In this configuration, both client and server computers use

        modems to transmit data in form of sound through the telephone

        lines system. The dial-up connection described in this chapter

        could be a choise when the only communication medium you have

        access to is the telephone lines system.
