How does RS-422 work?
Posted on 2006-07-18
Suppose I have two computers connected using an RS-422 line.
Computer #1 sends three separate messages before Computer #2 reads any message.
Can Computer #2 still read all three messages or are some of them lost?
In other words, does RS-422 use buffering?
If messages are lost, how can I avoid this? Using "Ready to Send" and "Clear to Send" lines?
