COM Port Middleware

Need coder to write middleware driver for a PHP application to communicate with a simple data logging device over a USB cable (COM port).? An example application written is in Visual Basic using the .NET platform ??" that source code is available as reference.? The VB source is the best specification ??" timeout values, etc.

?

The PHP application calls the driver and passes it one of these communication requests: Download Data, Reset Unit, Return Current Seconds, Return Serial Number, Set Audio Interval, Return Version Number, Return COM port.? The middleware driver then passes the results either directly back to the PHP application or makes it available in a temporary file.? Speed is an issue ??" the faster the better.

?

The simple data logging device is a personal dispenser that keeps track of every time it is used.? The PC application checks each dispenser out ??" keeping track of who it is assigned to and the base time.? The simple data logging device keeps an offset time and stores sequential time stamp records that are really just the offset time.? The records are downloaded to the application program using the needed driver called from a PHP application.
