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.
