•
Upon receipt of an SMS message and based on the configuration, the MultiModem iSMS sends the
SMS to the HTTP or TCP server.
If the post interval is zero seconds, the MultiModem iSMS uploads the message immediately upon
receipt of it. If the post interval is non-zero, it waits for the configured post interval, queues up the
messages, and then uploads the messages accumulated for the configured post interval.
The MultiModem iSMS will wait for an OK response from the server after sending the SMS to the
application via HTTP or TCP. The response timeout at the MultiModem iSMS is 30 seconds.
