RTS/CTS handshaking and waveforms

Rts+Cts+Working

Matt writes in about RTS/CTS handshaking and waveforms

I recently had the need to add RTS/CTS handshaking to the serial connection between my PC and my ATMega.  I struggled with it for a time due to some misunderstandings on my part, and because I couldn’t find a writeup which described how the handshaking is supposed to work, and (more importantly for me) how it’s supposed to look.  I eventually got it to work, and wrote it up in a way that would’ve been useful for me when I was trying to figure out how to make it work.
