Can anybody tell me how to send sms through WAVECOM multiport usb moden using C# ? I installed the drivers and connect a sim card. but I have no idea how to send sms from it. an A-type USB cable is connected the PC and the other end is B-type usb connector. I am using TATA docomo sim card for connection

== A-type USB output          B-type USB input

  • I guess you need to send it AT commands over the rs232 port. For a starter: http://stackoverflow.com/questions/5101217/rs232-serial-port-communication-c-sharp-win7-net-framework-3-5-sp1 – rene Dec 29 '12 at 12:30
