The Telnet URL scheme is used to designate interactive services that may be accessed by the Telnet protocol.
A telnet URL takes the form:
as specified in Section 3.1. The final "/" character may be omitted. If :<port> is omitted, the port defaults to 23. The :<password> can be omitted, as well as the whole <user>:<password> part.
This URL does not designate a data object, but rather an interactive service. Remote interactive services vary widely in the means by which they allow remote logins; in practice, the <user> and <password> supplied are advisory only: clients accessing a telnet URL merely advise the user of the suggested username and password.
