I don't remember who to thank for this one, which I modified only

on testForConnection
put "255.255.255.255:43222" into testSocket
open datagram socket to testSocket
put hostAddress(testSocket) into theIPAddress
close socket testSocket
if theIPAddress is "127.0.0.1" then
--it's the local machine address, so not connected
--may insert connection routine here
end testForConnection
That tests for having a *network* connection, but not for having an
*Internet* connection.
e.g. on my laptop, connected to my home network, this yields a value
(today it's 192.168.1.67) regardless of whether the DSL line is
connected and working or not.
I'm not even sure it adequately tests for a network connection - on a
machine with a single network port and a static IP address, I think it
might return that IP address even if the network was disconnected. I
don't have a suitable machine to test that out on, and anyway the test
would be incomplete because it could vary between OSes.
