Troubleshooting SMS Modems

If an SMS modem is not working as expected, verify that the communications port (COM port) to which the modem is attached is configured to use settings supported by the modem.

  1. In the Windows Control Panel, double-click Device Manager. The Device Manager appears.
  2. Expand Ports.
  3. Double-click the communications port used by the SMS modem. The Communications Port Properties dialog appears.
  4. Select the Port Settings tab.
  5. Using the documentation provided by the modem manufacturer, verify that the port settings listed are supported by the modem. If the listed settings are not supported, make any necessary changes.

    Note: If you are using the MultiModem® GPRS external wireless modem, model MTCBA-G-F2, set Flow Control to Hardware.

  6. Click OK to save changes.
