The Admin.html web page is the primary configuration user interface for managing host definitions, the web server and terminal emulation profiles.
Note that in mid-November of 2019 the location and name of the page was moved from macros/cfgadmin.htm to config/Admin.html.
If you have version prior to mid-November 2019, your page will still be Macros/CfgAdmin.htm to access this functionality.
Admin.html is found at the server with the url http://localhost/fvterm/config/Admin.html
