VMS Help TCPIP Services, TELNET, Starting  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    You can start a TELNET or TN3270 session with a remote host (also
    called establishing a connection and opening a connection) in one
    of the following ways:

    o  At the DCL prompt, issue either the TELNET or TN3270 command
       and specify a remote host.

    o  At the DCL prompt, issue the TELNET or TN3270 command with no
       parameters. At the TELNET or TN3270 prompt that appears, issue
       the CONNECT or open command, specifying a remote host.

    o  Invoke and use TELNET or TN3270 from a command procedure.
