如何让我的应用程序监听传入的SMS消息？

Question

I have a windows form App which is written to send and recieve texts, this is implemented by sending a message via .NET Remoting to a Service installed on a server, which has a GSM modem (dongle) connected to it, the service then sends the message through the GSM modem once it has a message from the Client App.

Everything's going well so far with regards to sending a text, However we need functionality to enable the reading of incoming text messages; I'm unsure how to go about writing my code to listen out for incoming texts, and then send them over to my Client App.

Could anyone give me some pointers on where to start please? I've tried MSDN Documentation on the TcpClientChannel Classes, but this doesn't prove useful for listening to the COM port or anything like that.

If you are using the AT command set then I'm afraid your server will have to poll the dongle's SIM for messages at an interval (whatever makes sense).

In terms or notifying the client you can either:

• follow the same scheme as the server and poll regularly

-or-

• if the remoting connection is open continuously, have the server notify using an event on one of your remoting objects. The event args for this event can contain all of the new messages.
