SMS sources

Headwind GSM Modem Driver can be used to send messages prepared by external applications or even remote URLs. The following types of SMS sources are supported:

File source: retrieve the SMS from a file;
Command-line source: use the output of a DOS command to send SMS;
URL source: retrieve the SMS from a remote URL.

After the SMS source is setup, Headwind GSM Modem Driver periodically asks the source for the SMS to send. The polling time is setup for each SMS source.

Generally, the SMS source must return an XML file of the following format:

<messages> <message msisdn="..." [flash="true"] [url="..."] [report="true"]>Message text</message> <message msisdn="..." [flash="true"] [url="..."] [report="true"]>Message text</message> ... </messages>

The "flash" attribute means that the SMS must be shown on the recipient screen. The "url" attribute contains the URL for WAP Push SMS. The message with the "report" attribute requires delivery report. Starting and ending tag <messages> may be omitted.

To manage SMS sources, click the "Sources" tab in the control panel of Headwind GSM Modem Driver. The tab contains a list of installed SMS sources. Click "Add" to add a new source, "Edit" to edit an existing source and "Delete" to remove a source.

If a source raises an error, it can be seen in a log file.
