John. I think you are confused. We are using dotsToChar so the input is a byte
containing a dot pattern and the output should be a char. So, unless I'm
mistaken, an input of 0X20 should return an ASCII comma ','.

Is that dot 6? I am passing the hex value 0x20, which the decimal value is 32.

If you are passing 32, which is a blank, in inbuf the outbuf should
contain 0. I'm not sure what is going on. The Java binding mey need
revision.
