sample.dip

# This is a sample file for the program 'dip'.
# 'dip' can be used to dial to a Internet provider and establish a SLIP
# or CSLIP connection.
#
# sample.dip	Dialup IP connection support program.
#		This file (should show) shows how to use the DIP
#		scripting commands to establish a link to a host.
#		This host runs the 386bsd operating system, and
#		thus can only be used for the "static" addresses.
#
# NOTE:		We also need an examnple of a script used to connect
#		to a "dynamic" SLIP server, like an Annex terminal
#		server...
