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’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.
