Keywords: handshake shake hand flow control

My impression is that handshaking is a way of doing flow control
thru hardware using some pins on the rs-232 (forgot the 3-letters
abbreviations) and xon/xoff is flow control thru software.
Is this correct? If so, what is the advantage/disadvantage of
handshaking compared to xon/xoff?

Also, can someone remind me what those pin names are and how the
protocol works? Thanks.
