I Haven't used this board but it might be important that you use the same compiler that was used to make the original code. Perhaps you need XC16 instead. I have done something similar and if you are using the Microchip TCPIP stac= k you can do like this for your button in the HTML code: The img thing is just to get the browser to load the file rfc.cgi from the webserver. Then you can capture the rfc argument (2020002 in this case) in HTTPExecuteGet() and do what you want with it with the PIC. /Ruben > Hello Group, >=20 > ebay #: 250960691555 PIC24 Web Server Demo Board > http://www.ebay.com/itm/Advancer-Ethernet-Development-Board-ENC28J60-Net-= Webpa > ges-Control-applications-/250960691555 >=20 > I have a need for a web based page that can send a text string to a=20 > serial port when a button on the web page is pressed.
