Thoughts on my RS-232 question?
Are there 1-way only components? 2-way only components? Components that work with both?
I believe the answer to your question is Yes to everything, the most common is simply 2-way only components? however they all will receive one way commands, and even though they may not have anything to reply to, they still work fine.
