Dear customer,                               Vienna, on January 23rd, 1996



Update of the Windows95 MDMZYXEL.INF file for the ZyXEL U-1496 modem series
----------------------------------------------------------------------------


You might have following question which comes from one customer who
asked in the ZyXEL support forum on CompuServe (GO ZYXEL):
>Help!! My ZyXEL 1496E (external) does not work with Win 95!!
>I heard about a hardware problem with this model. Is that true?
>Who can fix this problem and help me??

Answer: sorry guys - this is my mistake !
I wrote the Windows95 modem script files which are distributed with the
European (!) versions of Windows95.

For the U-1496 modem series there is a little line in the modem script
"MDMZYXEL.INF" which makes the working with those modem which have
firmware versions older then v6.0x ("ati0" will report you the firmware
version in those cases) impossible. Windows95 recognizes the U-1496x modem
but doesn't dial because of an initialization error of the S50 register
which doesn't exist in the firmware < v6.0x

This bug has been found first by a very popular Austrian TV-News moderator,
Josef Broukal, - so I have to thank him once more for his bug report !


There are two solutions:
------------------------
 1.) get a new Windows95 modem script for ZyXEL U-1496 series
     (here in CompuServe ("MDMZYX14.ZIP") oder on Internet
     ftp://ftp.ping.at/pub/users/zyxel/software/Windows95/mdmzyx14.zip),
     uncompress this file with PKUNZIP, copy the "MDMZYXEL.INF" into
     the \WINDOWS\INF directory. Then start the "modem install wizzard"
     in the "START/Settings/Control-Panel/Modems" and install your modem
     again !

 2.) upgrade the firmware of your old ZyXEL U-1496x to the current
     version v6.15 (in this case you will have to burn the firmware
     into two EPROMs and do a hardware/factory reset afterwards by
     pushing the D/V or Enter button while powering-on the modem)
     The advantage of the new firmware is Fax Class 1 for "faxing a file"
     with the MS At-Work-Fax which is included in Windows95 or WfW.

--------------------------------------------------------------------------


Please copy this new "MDMZYXEL.INF" (internal rev. 29, 01/23/96) into your
"\WINDOWS\INF\" directory and overwrite your old file. Then install your
ZyXEL U-1496xx modem entries once again - the Windows95 registry will be
updated automatically.


PS:   this MDMZYXEL.INF is still a betatest which has not yet been
      approved by Microsoft. Because of this betatest status there
      are some special debug informations included in the INF file
      itself, especially for the fax receiving. Therefor I added
      also Microsoft's "AWCMFG32.DLL" which should be copied to your
      "\WINDOWS\SYTEM" directory. This file will create a special
      logfile "FAX0.MON" on C:\. If you have any problems in
      receiving faxes with "At Work Fax" you can view & store or print
      this compressed logfile by using following "mouse click path":
      "MS Exchange & Inbox Settings Properties / Microsoft Fax Properties /
      Modem Properties / Advanced / View Log..."

      Any bugreports or suggestions for new modifications are welcome !
