The Java RCX API is used to communicate with the Lego Mindstorms RCX through the IR tower. This API was created to fill the void of a USB-based IR tower on the Win32 platform though the long term goal is not to be Win32 specific.
The USB connectivity is accomplished using native methods the the Win32 API. Specifically, the
CreateFile(), ReadFile(),
WriteFile(), and CloseHandle()
functions.
The architecture is designed such that adding other IR connectors is trivial.
