*The 1.5K-byte non-ARQ buffer allows data transfer with Xmodem- and Ymodem- type file

transfer protocols without using flow control

The 128-byte option lets remote users with slower modems keep data you are 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 does not exceed the size of their screen

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

characters
