I am trying to write some bits to the parallel port using the java communications port and all is okay except that i need some clarification on something.
The parallel port is connected to circuit board that needs nine inputs(or better known as nine bits) Now this is what i am doing to write the values to the parallel port
Now here is my problem, the output stream only seems to output to the first eights bits but does not output the last bit which is a zero. Now i know that a byte is eight bits but if i use a byte array it still does not work.
Basically my question is that i need to output nine bits but i seem to be able to only output eight bits and would really appreciate some guidance from anyone on this topic.
