List system configuration.

Syntax
      SYSTEMINFO [/S system [/U username [/P [password]]] ]
                    [/FO format] [/NH]

Key:
    /S  system         Remote system to connect to.
    /U  [domain\]user  User context under which to execute.
    /P  [password]     Password for the given user (will prompt if omitted)
    /FO format         Output format: TABLE, LIST or CSV
    /NH                No "Column Header" in the Table/CSV output
