Hi All,
Is there a library out there that can be used for sending serial modbus communications that hooks to processing? I have a pump which uses Modbus RTU in order to control the pump, as well as receive information as to the status of the pump (pressure, flow rate, remaining volume, ect.). I haven’t been able to find any sort of library for this, and am starting to think I may need to swap to another language that contains a library (they make a bunch for C and python from what I’ve seen). Any help would be super appreciated! If you need any additional info please let me know, I’m new to modbus protocol, so I might have accidentally left out some piece of critical information.
Thanks!

[Here is a Processing library](https://code.google.com/archive/p/processing-modbus/), with a link still downloadable [here](https://drive.google.com/folderview?id=0B0B286tJkafVSENVcU1RQVBfSzg&usp=drive_web).
I’ve never worked with it though.

This looks perfect! Thank you so much!
