The following subsections describe how to install the DUAL Link Interface
in FreeBSD 1.1. The sample code and a complete Berkeley Unix implementation
is available in machine readable form via anonymous ftp from Internet
host minnie.cs.adfa.edu.au (131.236.23.152), file pub/Dual/dual.tar.gz.
This is a gzip Unix tar file. It must be ftped in binary mode. Good luck!
