Hi,
Thanks for responding.
Have you heard of jamod? Its another modbus library for Java. I posted a question in Processing asking if I can use it in Processing API. Two users came back saying that they have successfully implemented the TCP option in jamod library. There is example code in Sourceforge that they directly just cut an pasted in the Processing API. I'm still waiting for an answer concerning the use of the modbus RTU option in Processing. The jamod requires the RXTX library also and since this is already included in Processing I dont know if it will work.
Do you know of more information on how to use the serotin modbus library?
So I can start testing. The jamod lib seems a bit more complicated then M4J lib.
