* 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.
