Does anyone know how to detect if the user has a modem in their system using C++? GetIfTable does a good job detecting network connections, but I need to know if they have a good o''l dialup modem.

I should think it''s different for each version of Windows but on XP you can look under:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Ras\Tapi Devices

to see a list of Telephony devices.

Like I say it''ll probably be different for NT, 98 etc.
