Detect incoming call from a GSM modem in c#

I am developing a C# application to make and receive calls from a GSM modem. I am using a timer_tick event to regularly read the port using port.ReadExisting() and comparing it with RING. If there is a match, display in a label that there is an incoming call. However I couldn't get it to work. Looking for suggestions.

           string s = port.ReadExisting();

               if (s.Contains("\r\nRING\r\n"))
               {
                   incall_status.Text = "Incoming Call....";
                   incall_status.Visible = true;
               }
