I have uploaded a very simple quick and dirty cgi script which can be used to control the si570 on the AMD5120 based Linux controller from a web page. Assuming that you installed apache on the router, you need to install the compiled si570.c and si570.cgi in: /var/www/cgi-bin/si570. Now point your browser to http://your_router_name_or_ip/cgi-bin/si570/si570.cgi. You will get a field to enter the frequency and some check boxes with some options.
si570.c and si570.cgi are here: http://groups.yahoo.com/group/softrock40/files/PA3BYA/ 73, Gerrit.
