Hi Is there any example of MODBUS implementation in pharo seaside ? Regards Marcos Hi Marcos, I don't know of any Modbus implementations. I proposed developing a native Smalltalk implementation for this year's GSoC [1] but it didn't get selected as a priority. I am still interested in developing one so I am curious as to your application. The other option would be interfacing to an existing C library using NativeBoost (but I haven't had any experience with that yet.) [1] http://gsoc2013.esug.org/projects/modbus regards -ben P.S.
