Using C# to send fax from real fax machine, connected to the computer

I would like to send fax message from my C# application. But I don't want to send "internet fax". I want to send fax from real fax machine.

Currently I don't have fax machine, but I will have a moment for test on my friend's machine. So I'm looking for an example (with C#, .NET4) or some clues. I've got Windows 7. But it will be good if it works also on Vista and XP.

Thanks in advance,

UPDATE: I want to write a C#-开发者_StackOverflowapp, which will be sending faxes from that real fax machine. (Like sms from mobile phone connected to the computer).

I'm not sure if you are using XP, but take a look at Faxing with XP and C#.

Try out GFI Faxmaker. You will be able to to XML API to create fax commands
