On Guard™: Faxback Server

Designed and developed software for an automated FaxBack Server for a unique, reusable radon testing device. The Faxback server hosts a bank of 16 modems and the custom application written to answer incoming calls. Communication with the remote device prompts the collection of radon readings, which the server stores in a database. Upon completion of the database entries, the server creates a unique Microsoft Word document with specific information required by various state agencies. At that point the server calculates readings and creates a Microsoft Excel spreadsheet which is inserted in the document, creating a chart of readings. Finally, an automated fax of the complete document is sent to the appropriate state agency.

This application also involved the development of a PDA and a laptop application for use by the radon tester. This user is able to connect the laptop or PDA to the radon detection device via RS232. The user may then use the device to phone the faxback server. The server process is started by the calling application.

The Faxback server project was written in Visual C++, Visual Basic, and VBA for Office, utilizing Office Automation of Word, Access and Excel.
