You can view the SCO online documentation with Netscape Communicator or another HTML browser by opening the following URL:


where document-server is either localhost (if the documentation is on the local system) or the fully qualified domain name of the document server.


Netscape Communicator is a comprehensive set of Internet and intranet components that integrates email, groupware, HTML editing, conferencing, and calendaring with the Netscape Navigator(TM) WWW browser. Netscape Communicator allows users to easily communicate, share, and access information using the latest Internet technologies.

The communicator command brings up the graphical Netscape Navigator(TM) browser. You can run it with or without options. If you include a URL or file location at the command line, the browser opens that location, rather than the default home page, at startup.

The communicator command is set up to start a child browser window automatically from an already-running browser if such exists. This can save system resources and improve performance for some systems. To disable this feature, set the NETSCAPE_NOAUTOREMOTE environment variable to ``true''.
