RFC 779 April 1981

TELNET SEND-LOCATION Option

4. Motivation for the option.

Many network sites now provide a listing of the users currently

logged in giving their names and locations (see the NAME/FINGER

protocol, RFC 742). The location is useful for physically locating

the user if he or she is nearby, or for calling them (a nearby phone

number is often included). However, for users logged in via the

network, the location printed is often no more than the originating

site name. This TELNET option allows the user's TELNET program to

send the user's location to the server TELNET so that it can be

displayed in addition to the site name. This functionality is

already present in the SUPDUP protocol (RFC 734).

5. Description of the option.

When the user TELNET program knows the user's location, it should

offer to transmit this information to the server TELNET by sending

IAC WILL SEND-LOCATION. If the server's system is able to make use

of this information (as can the ITS sites), then the server will

reply with IAC DO SEND-LOCATION. The user TELNET is then free to

send the location in a subnegotiation at any time.
