Disable FTP, Telnet, and ExpressNAV for GEOi2 and FCO3

Version 1

    Problem: In secure environments, it may be necessary to disable ethernet access to Neo FCO3 or GEOi2 V.I.A. cards.

    Solution:
    Use the following CLI command to disable or enable Telnet, FTP, and ExpressNAV (web interface) functionality. The Telnet/FTP/ExpressNAV parameters are cumulative; to close all three, ports, issue the ClosePort command three times, once for each port. The parameter "none" re-enables all ports.

    Usage:
    set ClosePort [Telnet | FTP | ExpressNAV | none]
    get ClosePort

    Note: this feature is not available on discontinued models FCO2, FCO1, GEOi, or GEOn.
