Summary of Change
-----------------
  Key: <n.nn>   Diskette version (for example, 1.00 means Version 1.00)
        (New)   New function or enhancement
        (Fix)   Correction to existing function
        (Restriction)  Remaining restriction

<2.22>
 - (Fix) Connectivity to some modems that violate V.34
       specifications has improved.

 - (Fix) The audio problem of not being able to play some
       wave files when using the 28800 modem is fixed in
       Windows 3.1 and Windows 95.

 - (New) An uninstall function has been added along with
       improvements to the installation.

 - (New) For a DOS/Windows 3.1 environment, the Mwave DOS and Windows
       installations and directories have been combined. Therefore,
       support for "DOS only system" is dropped.

 - (New) An Mwave-written application "Mwave Quick Tests" has been
       included, which helps you isolate problems quickly.

 - (Fix) The board driver has been modified to
       fix a general protection fault (GPF) problem
       during suspend mode.

 - (Fix) The problem of some wave files of a particular frequency
       not playing has been fixed.

 - (Fix) Some Class 1 fax fixes have been included.


 - (Restriction)
      The modem name in Windows 95 has changed slightly to
      "ThinkPad 28.8 Data Fax VOD Modem."  This can cause
      the Windows 95 dialer program or other Windows 95 applications
      to not recognize the modem.  Correct this by going
      to the Dialing properties of the application and
      changing the modem name to the new Mwave modem name.

 - (Restriction)
      The shutdown and "Exit to DOS" option from the
      Start button in Windows 95 will fail if Mwave release 2.22
      is installed over the previous preload.  The fix for
      this is to locate the "Exit to DOS" pif file in the
      Windows directory and edit the file to change
      references to the MWD directory to MWW and change the
      Mwave board driver to MWD50430.EXE.

 - (Restriction)
      Some games may require the SET BLASTER statement to
      include a T3 parameter to get sound.

 - (Restriction)
      The "Exit to DOS Mode" used in the preload
      will not allow the Mwave modem to work
      because the COM port is not in the BIOS data area.
      Therefore, some applications using Mwave may not work.

 - (Restriction)
      The New Zealand World Trade tables do not recognize a
      dial tone.   A patch is available if needed.
