Usage

Overview

alevtd is http daemon which serves videotext pages as HTML. Tune in some station with a utility like v4lctl or some TV application. Then start it and point your browser to http://localhost:5654/

Pages may be requested either in HTML format (http://localhost:5654/<page>/ or http://localhost:5654/<page>/<subpage>.html) or in ASCII text format (http://localhost:5654/<page>/<subpage>.txt). Subpage "00" can be used for pages without subpages.
