Hi
i have M1306B wireless modem. It works fine but some times modem stops working(does not responds to my AT Commands). I tried to find the problem and seems to be it happens when a ring comes on the modem. At the point its CTS (Clear To Send) and CD(Carrier Detect) pin changes.
Here is my log entries
COM 11 Pin Status Changed : Ring
COM 11 Pin Status Changed : CDChanged
COM 11 Pin Status Changed : Ring
COM 11 Pin Status Changed : CtsChanged
