Hi... http://www.ohmark.co.nz/news090120.html
etc... :-) Using libmodbus from launchpad (There's two libmodbus's around, one is crap, the other is the one I've contributed some bug fixes to. :-) ). If you're pic-aware You're welcome to have some of my test code, I've not done any work on this for a while, but I have a fully functional modbus RTU (rs485) setup, and sample code for GCC on linux, and VB/windows that has survived a fair bit of testing. Cheers, Me. On Fri, 2009-07-10 at 20:58 +1200, yuri wrote: > Does anyone on this list know anything about controlling ModBus relay > boards from a linux box? >
