* 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.
