[fpc-pascal] Ethernet Relays

[James Richters]

Yes 10 was too short,  I made it larger and larger until it worked.  1000 was the lowest value that worked so I set it to 2000, that's still quite a bit faster than the default.

If I make a mistake in the link but the server IP address is correct, I get a valid connection but then it fails and terminates with:
An unhandled exception occurred at $0000000100017675:
EHTTPClient: Unexpected response status code: 401

If I use the wrong IP address, but that IP address has a different server running on it, but that page is not available, I get:
An unhandled exception occurred at $0000000100017675:
EHTTPClient: Unexpected response status code: 401

Is there a way to obtain these errors as well so it doesn't terminate my program?

James

What timeout did you use ? 10 ms is probably too short.
