I was thinking about converting some of my protocol implementations to
plc4x, but I have only worked in the serialport space, (e.g Modbus/RTU
rather than Modbus/TCP).
There is a ancient Java specification (Java Comms API), which is not only
literally from last millennium, but rather poor as well.
So, what choices do we have?
* GNU has an implementation, which is rather bad Java code and the C/native
side needed a bit tweaking last time I worked with it.
* The best implementation I know is commercial, but perhaps we can entice a
code donation and/or a Apache Licensed API. I'll investigate that one...
* Our own implementation from scratch, which kind of belongs in Apache APR,
at least the C/native part.
