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.
Installation Guide
------------------
Refer to the "INSTALLATION NOTES" part in the README.TXT file
in the Mwave DSP Features Diskette for Windows 95 #1.
Note: If you install the Mwave feature in your ThinkPad computer
for the first time, you also need to install the Mwave DSP
