    I had been looking for a higher-functionality replacement to jamod, which seems to have been completely abandoned, despite claims by the administrator that it has been. I had been hopeful that modbus4j would have more of the Modbus messages covered, but it seems that it is another far-less-than-complete implementation of the Modbus protocol. That it is GPL'd, instead of LGPL'd is the nail in the coffin -- libraries really need to be under the LGPL so developers don't have to worry about the viral nature of the GPL in their applications. I'd give two thumbs down if I could, but one will have to do.
