Configuration File Overview
===========================

   UUCP uses several different types of configuration files, each
describing a different kind of information.  The commands permitted in
each file are described in detail below.  This section is a brief
description of some of the different types of files.

   The `config' file is the main configuration file.  It describes
general information not associated with a particular remote system, such
as the location of various log files.  There are reasonable defaults for
everything that may be specified in the `config' file, so you may not
actually need one on your system.

   There may be only one `config' file, but there may be one or more of
each other type of file.  The default is one file for each type, but
more may be listed in the `config' file.

   The `sys' files are used to describe remote systems.  Each remote
system to which you connect must be listed in a `sys' file.  A `sys'
file will include information for a system, such as the speed (baud
rate) to use, or when to place calls.

   For each system you wish to call, you must describe one or more
ports; these ports may be defined directly in the `sys' file, or they
may be defined in a `port' file.

   The `port' files are used to describe ports.  A port is a particular
hardware connection on your computer.  You would normally define as
many ports as there are modems attached to your computer.  A TCP
connection is also described using a port.

   The `dial' files are used to describe dialers.  Dialer is
essentially another word for modem.  The `dial' file describes the
commands UUCP should use to dial out on a particular type of modem.  You
would normally define as many dialers as there are types of modems
attached to your computer.  For example, if you have three Telebit
modems used for UUCP, you would probably define three ports and one
dialer.

   There are other types of configuration files, but these are the
important ones.  The other types are described below.
