Ray, The header info I supplied and the info that I am getting back from the OS Controller with FW 2.2.0 does not really give me anything I can go off of. If there a log available on the controller itself I can get. I could supply you with my app. The msWinsock ocx is an activex control that comes with Visual Basic. I am simply setting the port to 80 and connecting to the open sprinkler IP and sending the Get command. I get the proper response back from OS FW2.19 and below. Just not the 2.2.
Let me know if want to try it or if their is a way to get the log from the OS controller.
