faxcomexlib and multiple fax modem cards

[C# Programming]

I have in place an application that sends faxes using a single modem card loaded on a server. I am installing a second modem card on the server and I was wondering if anybody out there knows how it will effect my current coding. I am trying to allocate traffic to both cards, is that done automatically by windows? How will the statuses be reported?

Please help as I can't find any information or manual that explains this.

Thank you in advance
