The Macintosh included a standard set of two ports for connection to a printer and a modem, but some PowerBook laptops had only one combined port to save space.
When the receiver’s buffers approach capacity, the receiver sends the XOFF character to tell the sender to stop sending data.

The advantage of hardware handshaking is that it can be extremely fast; it doesn’t impose any particular meaning such as ASCII on the transferred data; and it is stateless.
Its disadvantage derial that it requires more hardware and cabling, and these must be compatible at both ends.
