SMS handlers and sources

SMS handler is a script called by Headwind GSM Modem Driver when a short message is received. Our company offers the development of such scripts using VBScript language. The SMS handlers may solve different problems, for instance:

• Run a command on PC according to the message content and sender number;
• Autoresponder (choose the reply according to the message content and sender number);
• Write incoming SMS in a database (for example, MySQL);
• Forward incoming SMS to e-mail;
• Post incoming SMS to web site.

SMS source is used by Headwind GSM Modem Driver to send short messages. Headwind GSM Modem Driver requests an SMS source for outgoing messages and sends them if necessary. There are multiple types of SMS sources:

• Command. Headwind GSM Modem Driver calls a command or a script returning outgoing SMS in a special (XML) form.
• File. A file is checked time-to-time. If the file is not empty, Headwind GSM Modem Driver retrieves SMS from it and sends them. This type is convenient for using with another applications.
• URL. Headwind GSM Modem Driver downloads a special web page.
