Dear ZyXEL customer,                                    Vienna, 11/26/1998


-----------------------------------------------------------------------------
    Update of the European "MDMZOS90.INF" modem definition script file
                 for the ZyXEL Omni 288s analog MODEM
      for firmware version v1.21 (06/28/1998) and v2.00j (11/25/1998)

              This file is for following operating systems:
              Microsoft Windows95 v4.00.950 and OSR 2 (aka 950b)
              Microsoft Windows98 v4.10.1998.6
              Microsoft WindowsNT v4.00.1381 (with Service Pack 4)

              and for the latest betatest technical previews:
              Microsoft WindowsNT v5.00.1877   (Beta 2)
-----------------------------------------------------------------------------


1.) Installation:
-----------------
 +  In the Windows modem wizard (start | settings | control panel | modems)
    you should remove all existing modem entries for the ZyXEL Elite 2864.

 +  Please check your \WINDOWS\INF\ directory for already existing files
    (older versions) of the MDMZYXLG.INF, MDMZYXOS.INF or MDMZYX28.INF.
    All these existing files should be renamed to *.OLD

 +  Check that there don't exist any other "OEMx.INF" ('x' is a digit)
    files for the ZyXEL Omni 288s MODEM in the \WINDOWS\INF\ directory.
    Have also a look into the \WINDOWS\INF\OTHER\ directory, if it
    exists (new in Windows98 and NT 5.0)
    You'll have to look into the "OEMx.INF" by opening it with the
    NOTEPAD.EXE (or any other ASCII editor). If the "OEMx.INF"
    starts with the header which lets you assume it is for ZyXEL modems,
    then please rename (or delete) this file !

 +  Then install your ZyXEL Omni 288s analog MODEM once again
    by using the "modems" wizard in the control panel. Don't let Windows9x/NT
    search for the new modem but add the new hardware manually !
    You will be prompted to enter the path where Windows9x/NT could find
    the new INF driver file. Select the corresponding modem entry.


2.) LOGWIN.EXE and LOGGER.VXD (for Windows95 only)
--------------------------------------------------
    This is a utility (copyright by Microsoft) which lets you watch the
    logfile and trace information of the "MODEMLOG.TXT" (for the AT commands
    and modem responses) and the "PPPLOG.TXT" (PPP trace information) in a
    window ONLINE (!), that is WHILE IT HAPPENS !

    how to install it ?
    -------------------
    + manually copy the "LOGGER.VXD" into the \WINDOWS\SYSTEM\ directory
    + manually copy the "LOGWIN.EXE" into the \WINDOWS\ directory

    how to start it ?
    -----------------
    a.) you have to enable the logfile feature in the modem's advanced
        settings. Open the modems wizard applet which you will find under
        "Start | Settings | Control Panel | Modems",
        then select any modem entry and click on the "Properties" button
        and enable the "Record to a logfile" on the "Connection , Advanced"
        dialog box. In this INF file it is already pre-selected, so normally
        you don't need this step. If the "LOGWIN" utility is not used, then
        Windows95 will create a file "MODEMLOG.TXT" in the \WINDOWS\
        directory.
        Note: under Windows98 you will find the modem logfile in the
        \WINDOWS\SYSTEM\ directory with a long filename: "MODEMLOG_ZyXEL..."


    b.) if you want to enable the "PPPLOG.TXT" logfile feature, you must
        enable it in the advanced network settings for the "dial-up adapter":
        Open the network wizard applet which you will find under
        "Start | Settings | Control Panel | Network". Then select the
        "dial-up adapter", click on the "properties" button and choose the
        "advanced" dialox box. There the value for the "Record a log file"
        property must be set to "yes"

    c.) manually start the "LOGWIN.EXE" before dialing whenever you want to
        watch or debug the INF files !

  Originally this utility is included in the Modem Development Kit (MDK),
  which is publically available on Microsoft's Internet site.
