--- Code: ---==>defaultconnect();
Sending connect request to 98.227.200.17 for /shares/USB_Storage/testdoc.txt
Connected
GET /shares/USB_Storage/testdoc.txt HTTP/1.0

Disconnected
--- End code ---
I just copied and pasted the onbinchuck function out of some other coding help topic somewhere, I'm thinking it was the one ipq linked.
I also verified to make sure it was working by sending a request to forum.blockland.us and it downloaded some broken html something that ends like halfway through a line of code, but it still was called. I'll attach it in case someone cares.

There is about a five second delay between when the GET request is sent and Disconnected appears

Also I have tried like a million variations on the GET request, but this is the one that I am pretty sure Ephialtes indicates is best.

Why are you using binary content retrieval for a plain text file?

No idea, what would you suggest?

If you need to save the file, create a file object and open a file for writing upon connecting, write lines when recieved (make sure you don't write the header to the file) and close/delete the file object when disconnected or done receiving data. You may want to add a line "timeout" to automatically close/delete the file object in case the web server doesn't send Content-Length and doesn't disconnect you either (most web servers respect the Connection: close header though).

Sounds good, but how do I detect when lines are recieved?
