With the TELNET software in TCP/IP Services, you can log in to
    a remote internet system. This is called establishing a TELNET
    session. Your terminal appears to be attached directly to the
    remote system.

    You can establish a TELNET session with a host that uses IBM 3270
    model terminals (TN3270).

    Note that you can also use RLOGIN to log in to remote internet
    hosts. However, RLOGIN does not have the ability to manage a 3270
    session.

    To use the network terminal services, you need the following:

    o  A user account on the remote host also running TELNET

    o  A user account on the OpenVMS system that runs TCP/IP Services

    For more information about specific TELNET commands, enter the
    following command:

    $ TELNET
