Ok, on a CPE that fails, here is the request and response:

Hypertext Transfer Protocol
     GET / HTTP/1.1\r\n
         [Expert Info (Chat/Sequence): GET / HTTP/1.1\r\n]
         Request Method: GET
         Request URI: /
         Request Version: HTTP/1.1
     Host: 216.211.179.18:7547\r\n
     Connection: keep-alive\r\n

Hypertext Transfer Protocol
     HTTP/1.1 404 Not Found\r\n
         [Expert Info (Chat/Sequence): HTTP/1.1 404 Not Found\r\n]
         Request Version: HTTP/1.1
         Status Code: 404
         Response Phrase: Not Found
     Content-Type: text/html\r\n
     Transfer-Encoding: chunked\r\n
     Server: RomPager/4.07 UPnP/1.0\r\n
     EXT:\r\n

So on this particular CPE, the URL / cannot be found.  Any idea how I 
would know the correct URL?  And if I have that, how would I modify 
genieacs to use it?

And here is a request / response for a CPE that worked (different 
manufacturer):

Hypertext Transfer Protocol

     Connection: keep-alive\r\n

And it goes on to have a successful real-time GetParameterValues call.  
The URL for this one is also /, but it works on this device.

Any ideas?  And thanks again.
