6.1 The isdnd.rc Configuration File Format

The isdnd.rc file is a normal ASCII file. A line starting with the character ``#'' starts a comment line. An empty line or a line starting with a blank is ignored. The general syntax for all configuration statements in this file is

keyword = value

where keyword starts in column 1 and may be followed by no, one or more spaces or tabs, followed by the equal sign ``='', which may be followed by no, one or more spaces or tabs and a valid value for this keyword.

The configuration file must have at least two sections, a system section started with the keyword system (without an equal sign and a value) followed by no, one or more system configuration statements. The sytem section may be followed by a controller section started with the keyword controller (without an equal sign and a value) followed by no, one or more controller configuration statements.The controller section (if present;otherwise the system section) must be followed by one or more entry sections started with the keyword entry (again without an equal sign and a value). Each entry section contains several entry section configuration statements.
