For the invoking command syntax, type "hargs".

        If the "-t <terminal type>" portion of the invoking command is
        omitted, then you will be subjected  to  an  interrogation  to
        determine the terminal type.

        'Se' recognizes over 30 different terminal types, which is too
        many to list here. Do a 'help se' for details on what kind  of
        terminal types are valid.
