INTERNET_CONNECTION_MODEM EQU 1
INTERNET_CONNECTION_LAN EQU 2
INTERNET_CONNECTION_PROXY EQU 4
INTERNET_CONNECTION_MODEM_BUSY EQU 8
INTERNET_RAS_INSTALLED EQU 10h
INTERNET_CONNECTION_OFFLINE EQU 20h
INTERNET_CONNECTION_CONFIGURED EQU 40h
INTERNET_CONNECTION_MODEM_BUSY is documented as "no longer used"
but that does not tell you if any previous OS's still use it

If the "local system's modem is busy with a non-Internet connection" interpretation is correct, then whether or not a previous version uses it is probably irrelevant.

so, the point was - let's keep it, even if the docs say "no longer used"
if they said "no longer used, at all", i might have gone a different way :lol
this one is for InternetCheckConnection
FLAG_ICC_FORCE_CONNECTION EQU 1
