Telnet Linemode Option

Status of this Memo

This RFC describes a proposed elective standard for the Internet

community. Hosts on the Internet that support Linemode within the

Telnet protocol are expected to adopt and implement this standard.

Distribution of this memo is unlimited.

Overview

Linemode Telnet is a way of doing terminal character processing on

the client side of a Telnet connection. While in Linemode with

editing enabled for the local side, network traffic is reduced to a

couple of packets per command line, rather than a couple of packets

per character typed. This is very useful for long delay networks,

because the user has local response time while typing the command

line, and only incurs the network delays after the command is typed.

It is also useful to reduce costs on networks that charge on a per

packet basis.
