TELNET TERMINAL TYPE OPTION

Status of This Memo

This RFC specifies a standard for the ARPA Internet community. Hosts

on the ARPA Internet that exchange terminal type information within

the Telnet protocol are expected to adopt and implement this

standard. Distribution of this memo is unlimited.

This standard supersedes RFC 884. The only change is to specify that

the TERMINAL-TYPE IS sub-negotiation should be sent only in response

to the TERMINAL-TYPE SEND sub-negotiation. See below for further

explanation.

1. Command Name and Code

TERMINAL-TYPE 24

2. Command Meanings

IAC WILL TERMINAL-TYPE

Sender is willing to send terminal type information in a

subsequent sub-negotiation

IAC WON'T TERMINAL-TYPE

Sender refuses to send terminal type information

IAC DO TERMINAL-TYPE

Sender is willing to receive terminal type information in a

subsequent sub-negotiation

IAC DON'T TERMINAL-TYPE

Sender refuses to accept terminal type information

IAC SB TERMINAL-TYPE SEND IAC SE

Sender requests receiver to transmit his (the receiver's) terminal

type. The code for SEND is 1. (See below.)

RFC 930 January 1985

Telnet Terminal Type Option

IAC SB TERMINAL-TYPE IS ... IAC SE

Sender is stating the name of his terminal type. The code for IS

is 0. (See below.)

3. Default

WON'T TERMINAL-TYPE

Terminal type information will not be exchanged.

DON'T TERMINAL-TYPE

Terminal type information will not be exchanged.

4. Motivation for the Option

This option allows a telnet server to determine the type of terminal

connected to a user telnet program. The transmission of such

information does not immediately imply any change of processing.

However, the information may be passed to a process, which may alter

the data it sends to suit the particular characteristics of the

terminal. For example, some operating systems have a terminal driver

that accepts a code indicating the type of terminal being driven.

Using the TERMINAL TYPE and BINARY options, a telnet server program

on such a system could arrange to have terminals driven as if they

were directly connected, including such special functions as cursor

addressing, multiple colors, etc...
