Barionet

The Barix Barionet is a range of network-enabled, programmable automation controllers for automation that connects to digital, analogue and serial (RS232 and RS485) connected sources. The main unit contains a complete IP stack including its own web server. It is also an application platform being programmable in Barix Control Language (BCL), a cut-down version of Basic.
Using BCL I have written a xAP BSC v1.3 framework that allows input and output control of all the Barionet's functions via xAP. Extending this would allow you to write a complete embedded xAP control system (e.g. for heating control) using the Barionet.
Send a post to the xAP Yahoo! group if you are interested in this code.
