Mondor Nokia DLL Description:

This is an ActiveX DLL that allows you to control SMS messaging through your compatible Nokia mobile phone. You can send, receive and manipulate your SMS messages, logos and melodies from any ActiveX enabled environment - ASP script, windows application, windows scripting host script, Microsoft Office document and other.

Not only that. Also, full version allows you to send/receive logos and work in multithreading tweaked environment, with no latency in sending SMS.

This control is event-driven, but ASP does not support events, so there is a possibility to save all incoming messages to the folder of your choice. So when you can use events - use them, when you cant - there is no problem.
