Hello, I'm bidding just to send along information as there exists already an open-source project : libmodbus, that should serve your needs and can be easily cross-compiled for your architecture. I can certainly assist if you need something more comprehensive which wraps the libmodbus library, as I worked extensively with various protocol implementations and embedded Linux development in general. Please feel free to contact me for more information or to discuss your project in more detail. Thanks, Mitch

We have already implemented Modbus RTU Master in embedded Linux on Rasberry, ICOP, Winsystem boards with serial RS232 and RS485 interfaces. Configuration are stored in XML for Master and its slaves. So I think we are having enough experience and most of the work already done as per your requirement, which makes us right candidate to get this project.
