♦♦The 128-byte option lets remote users with slower modems keep data you’re sending from scrolling off their screens. When remote users send your computer an XOFF (Ctrl-S) and you stop transmitting, the data in transit from your modem’s buffer doesn’t exceed the size of their screen.

This is also very helpful in situations when a remote modem/ printer application is losing characters.
