Q7521050: When I send a test SMS message using my GSM modem, I get the following error: 30203. What does it mean?

This error only occurs when using Windows Telephony devices (like 'Standard 9600 bps Modem'). The Windows Telephony device name is valid,. There can be two reasons for this error:

  1. The Windows Telephony device is already in use by another application;
  2. The port speed is wrong; Windows is able to open the port, but is not able to initialize the device properly because of the wrong speed. Make sure that the port speed of the device and the port settings of the Telephony device in the Control Panel both match.
