There is no direct cgi code provided for making those changed individually on that page. However, if you are good in CGI coding, you can analyze how browser sending the information to the WC board, and do that in the same way. Basically, each page's data is encoded into hex ASCII code then send to the board. There is a URL in the web browser to let board know which page the data is from. User ID and password are base 64 encrypted, can be send in together to avoid asking login manually.
If you install a Wireshark software on PC and watch the IE browser communicate with WC, you can see everything being send back and forth.
By changing a field value, you can easily see what to send in will have what result.
