I have written a program to read and send SMS using GSM modem. I have used a thread to collect unread SMS from GSM MODEM using AT command, which run in every 10 second. On the other side, I am using GSM COMM DLL to send the SMS by close the AT connection and connect the modem through GSMCOMM DLL.
Questions:
1. Is there any possibility to damage modem for more and more connecting and disconnecting the modem?
2. Is here any possibility to damage modem for collecting unread SMS in every 10 second.

I don't think so.
The only thing that gets affected is the performance.

Well, if you are so worried, why don't you use AT+CNMI command instead of polling the modem every few seconds. You said you are using GSM Comm Library. There must be some method to enable message auto receive alert. Check it out.

Hope this helps.:thumbsup:
