Internet Check
by rbytes, November 2018
Uses PING to check internet status
refname$ should be a website that is always up, such as "www.apple.com"
-If chk is 2, internet is live and the website name$ is active
-If chk is 1, internet is live, as indicated by successful
PING of website refname$, but the website name$ is not active
-If chk is 0, the internet is disconnected
My tests indicate that pinging an active website with "[name].com" or "www.[name].com"
returns 1, but pinging it with "http://[name].com" or "https://[name].com" always returns 0
You must use the form PING([name],port), with port=80 to get a response of 1.
To test this program:
a. Run it with name$ and refname$ set to active websites. chk will = 2
b. Run it with name$ deliberately misspelled. chk will = 1
c. Run it with your device in Airplane mode. chk will = 0
