    Thats the "cross over" cable I mentioned* :-)

    *although a null-modem cable normally includes cross-over, it does need to.

    *NO*
    A "cross over" cable connects two Ethernet ports. https://en.wikipedia.org/wiki/Medium-dependent_interface#Auto_MDI-X

    A "null-modem" connects two DTE or two DCE together. https://en.wikipedia.org/wiki/Data_circuit-terminating_equipment https://en.wikipedia.org/wiki/Data_terminal_equipment https://en.wikipedia.org/wiki/Null_modem

    IOW connect COM ports of two computers to each other.

    P.S. I've been using null modems for >50 years ;}
    Ethernet is only ~30 years old.
    https://en.wikipedia.org/wiki/Ethernet




    But its still a good idea to first connect to a known-to-be-good device (the modem or smart switch (or anything else with a web-accessible setup) I mentioned) so that you can see your fixed IP actually works (on both 'puters), _before_ you try that cross-over cable (I'm not sure you realize, but now you've introduced a _third_ location that could give you troubles with setting up such a 'puter-to-'puter connection).

    I have two Lenovo laptops. One running WinXP Pro. The other runs

    I wish to create a minimal network. It will consist of only those
    two machines.
    Neither will have any internet connectivity.

    I've found a number of web references to setting static IP
    addresses on Windows machines.
    *HOWEVER* assume internet connectivity by one/both machines.

    Can anyone point me to any documentation EXPLICITLY covering my
    {admittedly} peculiar requirement.

    TIA

    The minimal network was being pursued as it was a close as I *HAD
    THOUGHT* I could come to a "null modem cable".
    A USB implementation is available -
    http://www.mouser.com/ds/2/163/DS_USBNMC-5030.pdf .
    I'll check local suppliers.
    Will also continue pursuing the LAN solution for its educational
    value.
