Installing a modem file

Hi all,

we have a self developed inf file with modem settings. this file works
properly when it is installed via "control panel -> Phone and modem options
-> add modem"

Now I'd like to install this inf file by using an installer, but I've no
idea how I should deal with the available inf file.

Is there any system command or API to add a modem file (inf) to the
registry?

How should I start with this challenge?

Thanks for any hint.

Alex
