Answering Incoming Calls
In addition to polling, capability to answer incoming calls is needed for
allowing remote service connection through the modem connection.
To enable the QML logger to answer incoming calls or to process
inbound SMS messages, select the Answer incoming calls option.
SMS Polling
Although the QML logger can be configured to reply to incoming SMS
messages, a weather station with one GSM modem is not suitable for
applications where heavy inbound traffic is to be expected.
The SMS polling is meant to be used either for retrieving the data
periodically or to serve as a backup for automatic SMS transmissions.
Service Operation
The service connection can be opened through the modem if the Service
connection enabled option in the Configure frame of the Optional
hardware view is checked for the port to which the modem is
connected. In addition, select the Answer incoming calls option.
