Experience of sending and receiving SMS from a custom C# app

---

We have an application that was written for the ipaq 3970 with a PCMCIA jacket and a GSM card,(normally nokia cardphone). We sent and received SMS messages via standard AT commands. Our code was initially VB but we had to rewrite it using c# for performance reasons.
Has anybody managed to write an app for the XDA ii to send and receive SMS messages? If so how did you manage it, ie via AT commands or some other integrated API that is available on the XDA.
Does any of the XDA embedded software interfere or prevent a custom written app from intercepting SMS messages?

Any tips or pointers would be very much appreciated before we commit to buying a XDA only to find that it will not work as we intend.

Did you look at OpenNetCF? They have some .NET classes for sending/receiving SMS messages and interacting with the SIM.

Let me know if that does it for you.

thanks, at first glance it looks to be a top link for exactly what we want to do. I'll let you know how we get on,
Have you used theses classes yourself for sending/receiving SMSs?
cheers,

Thanks for the gnokki link although I think porting it to CE would be a headache and it doesnt seem to support the XDA.
It might come in usefull elsewhere though.

Has anyone used software from a company called Derdack to manage the sending and receiving of SMS messages on windows platform?
