Telnet X Display Location Option

Status of This Memo

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

the Internet that transmit the X display location within the Telnet

protocol are expected to adopt and implement this standard.

Distribution of this memo is unlimited.

This standard is modelled on RFC 1079 [1], the telnet terminal speed

option. Much of the text of this document is copied from that RFC.

Motivation

When a user is running the Telnet client under the X window system,

it is useful for the remote Telnet to know the X display location of

that client. For example, the user might wish to start other X

applications from the remote host using the same display location as

the Telnet client. The purpose of this option is to make this

information available through telnet connections.

1. Command Name and Code

X-DISPLAY-LOCATION (XDISPLOC)

Code = 35

2. Command Meanings

IAC WILL X-DISPLAY-LOCATION

Sender is willing to send the X display location in a

subsequent sub-negotiation.

IAC WON'T X-DISPLAY-LOCATION

Sender refuses to send the X display location.

IAC DO X-DISPLAY-LOCATION

Sender is willing to receive the X display location in a

subsequent sub-negotiation.

IAC DON'T X-DISPLAY-LOCATION

Sender refuses to accept the X display location.

IAC SB X-DISPLAY-LOCATION SEND IAC SE

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

display location. The code for SEND is 1. (See below.)

IAC SB X-DISPLAY-LOCATION IS ... IAC SE

Sender is stating his X display location. The code for IS is

0. (See below.)

3. Default

WON'T X-DISPLAY-LOCATION

The X display location will not be exchanged.

DON'T X-DISPLAY-LOCATION

The X display location will not be exchanged.

4. Description of the Option

WILL and DO are used only to obtain and grant permission for future

discussion. The actual exchange of status information occurs within

option subcommands (IAC SB X-DISPLAY-LOCATION...).

Once the two hosts have exchanged a WILL and a DO, the sender of the

DO X-DISPLAY-LOCATION is free to request the X display location.

Only the sender of the DO may send requests (IAC SB X-DISPLAY-

LOCATION SEND IAC SE) and only the sender of the WILL may transmit

actual X display location (within an IAC SB X-DISPLAY-LOCATION IS ...

IAC SE command). The X display location may not be sent

spontaneously, but only in response to a request.

The X display location is an NVT ASCII string. This string follows

the normal Unix convention used for the DISPLAY environment variable,

e.g.,

:[.]

No extraneous characters...
