----------------------------------------------------------------------
2.5  Using the LAN Installation Feature in Windows
----------------------------------------------------------------------

Use the LAN installation feature in Windows to install Mwave from a
shared disk connected to a local area network (LAN).

o   Initial Setup:

    1.  Create a directory structure to hold all the Mwave diskettes.
        Copy the related diskettes into the directory.  One method is to
        use XCOPY with the /S switch.

               XCOPY A:\*.* /S C:\MWAV_WIN

        An example directory structure follows:

                Example Path             What diskettes to XCOPY
                ============             =======================

             x:\CID\MWAV_WIN          Mwave Windows Diskettes 1 and 2
             x:\CID\SAMP_WIN          Mwave Samples Windows Diskette 1
                                        and Common Diskettes 2-6

             (Where x is the network drive where you will copy
             these files.)

    2.  The CID.LST file is on the first diskette for Windows and both
        MIDI Samples Install diskettes.  These files contain the auto-
        matic installation information needed to use the LAN installation
        feature.  The CID.LST file contains the Mwave installation
        defaults, but you may modify them to change the destination of
        the Mwave software.

o   Windows Installation Procedure:

    1.  Go to the workstation where you want to install the Windows Mwave
        software.  For Windows 3.x, select FILE and RUN from the Program
        Manager.  For Windows 95, select START and RUN.  From the RUN
        window type:

             x:\CID\MWAV_WIN\SETUP.EXE y:\CID\MWAV_WIN CID.LST

        (Where x:\CID\MWAV_WIN\SETUP.EXE is the fully-qualified path to
        the shared disk where the installation files reside and where
        y:\CID\MWAV_WIN is the fully-qualified path to the location of
        the CID.LST file.)

    2.  After the install is complete, shut down Windows and reboot the
        computer.

    3.  Go to the workstation where you want to install the Mwave MIDI
        Samples from Windows.  From the RUN window, and type:

             x:\CID\SAMP_WIN\SETUP.EXE y:\CID\SAMP_WIN CID.LST

        (Where x:\CID\SAMP_WIN\SETUP.EXE is the fully-qualified path to
        the shared disk where the installation files reside and where
        y:\CID\SAMP_WIN is the fully-qualified path to the location of
        the CID.LST file.)

    4.  After the install is complete, shut down Windows and reboot the
        computer.

----------------------------------------------------------------------
2.6  Turning Mwave OFF and ON in DOS
----------------------------------------------------------------------

NOTE:  The following section applies when you shutdown or boot to:

    -   Native DOS only from Windows 3.x
    -   MS-DOS mode only from Windows 95

If you are running Mwave under DOS only, type the following commands from
the DOS prompt:

o   MWAVE OFF--To turn Mwave off
o   MWAVE START--To re-initialize Mwave and begin a fresh session without
    rebooting
o   MWAVE ON--To restart Mwave with the same settings as the previous
    session

3.0  FREQUENTLY-ASKED QUESTIONS (FAQs)
======================================================================

This section contains answers to questions about certain features and
capabilities provided by Mwave applications.

----------------------------------------------------------------------
3.1  FAQs about the Mwave Modem
----------------------------------------------------------------------
Q: What should I do to change the speed of the modem speed to 33.6K bps?

A: Open the Mwave modem panel, select Options/Settings and activate the
   33600 (V.34) selection.

Q: What should I do if I answer an incoming phone call with the handset
   and then discover that the call is a fax or modem transmission?

A: Fax machines and modems are usually set up to call back several times
   if they fail to make a connection.  Therefore, hang up and, when the
   fax machine or modem calls back, allow the PC to answer the call.
   Mwave enables the PC to discriminate (determine the call type) and
   either pass the call to the open fax or modem application, or take a
   message for a voice call.

Q: Why don't I hear modem sounds when I run the Microsoft Hardware
   Compatability Test (MHCT) for the modem?

A: The MHCT tests the modem's M2 command.  M2 is the command to keep the
   speakers on all the time.  Mwave's DSP maps the M2 command to M1,
   which commands no sound when the modem is connected.  Therefore, no
   sound is heard when tested.

Q: How do I get Windows 95 to automatically load the Mwave Modem when
   Windows 95 starts?

A: Add the following command to the "RUN=" line of the Windows section in
   the WIN.INI file

       X:\MWW\MODEM\MWMWIN.EXE

   after any existing commands.

Q: What settings do I need to use when I install a communications appli-
   cation (such as ProComm or CrossTalk)?

A: Your communications software requires that you provide a modem type, a
   baud rate (i.e, the speed of your modem), and the COM port to which
   the modem is attached.

   The chart below describes settings required by Mwave:

       To set this...        Select highest ranking available setting...
       -------------------------------------------------------------------
       The Modem type        1. Mwave modem
                             2. Generic Hayes-type modem
                             3. User-defined modem
                             4. Hayes SmartModem 2400
                             5. Hayes modem
                             6. Hayes compatible modem
                             7. Other (Note: If you select a modem of
                                   type "Other," you must include the
                                   proper modem initialization string.
                                   For most applications, the
                                   initialization string "AT&F" will
                                   work. See the Mwave Modem online
                                   help for more information.)

       Baud Rate             57,600 bps, or the maximum setting offered
                             by your communications software.

       COM Port              COM 2

Q: What can I do if my 300 baud modem connections are unreliable?

A: Use the next higher setting (or baud rate) and try again. It is recom-
   mended that you use the highest possible setting of your Mwave Modem.

Q: What port speed should I use when I connect my modem at 2400 bps?

A: If you attempt to force the modem to connect at 2400 bps by setting
   the port speed to that value, the connection may not be made or it may
   fall back to 2400 nECL or 1200.  To avoid this problem, set the port
   speed to a higher value.

Q: What host application transfer protocol is recommended for best Mwave
   Modem performance?

A: For best throughput when sending or receiving data, select the
   highest-ranking available transfer protocol listed here.

   1.  ZMODEM
   2.  Kermit-95
   3.  Ymodem-G
   4.  TEXT
   5.  ASCII
   6.  XMODEM (only as a last resort)

   For more information, see Section 5.1  Recommendations for Optimum
   Mwave Modem Performance.

----------------------------------------------------------------------
3.2  FAQs about Mwave FAX Capabilities
----------------------------------------------------------------------

Q: What setting should I use for the "fax/modem type" when I set up my
   Class 2 FAX software to work with Mwave if "Mwave Modem" isn't listed
   as an option?

A: For all FAX applications, if "Mwave Modem" is not listed, select
   "Generic Class 2" or some comparable label from the application's list
   of supported fax/modems.

Q: What should I do if I answer an incoming phone call with the handset
   and then discover that the call is a fax or modem transmission?

A: See first Q & A in the above section, FAQs About the Mwave Modem.

Q: What are Mwave's fax restrictions?

A: Mwave supports fax transmissions of monochrome text and images up to 8
   1/2 inches wide (A4 width).  Mwave does not support B4 width trans-
   missions.

Q: I am using FaxWorks Voice and have difficulty receiving a fax when the
   SENDING machine is using Mwave Version 1.0 or 1.1.  Is there any way
   to correct the difficulty?

A: Recording a new outgoing greeting in the FaxWorks Voice application
   may correct the situation (check "Record a New Greeting" in the
   FaxWorks Voice help).  Upgrading the SENDING machines Mwave to Version
   2.0 will also correct the problem.

Q: Is there any way to correct the difficulty I have sending a fax using
   Microsoft FAX?

A: Uninstalling and reinstalling the fax application (using Add/Remove
   Programs in the Control Panel) corrects the problem.

----------------------------------------------------------------------
3.3  FAQs about Mwave Audio Features
----------------------------------------------------------------------

Q: Can I use the Windows 95 mixer interchangeably with the Mwave mixer?

A: The standard Microsoft mixer application was not designed for the
   Mwave hardware platform.  Therefore, you should only use the Mwave
   audio mixer for controlling audio.  To access the Mwave mixer click
   Start, point to Programs, point to Mwave Thinkpad, and click Mwave
   Audio.

   NOTE:  To place a shortcut icon for the Mwave mixer on your desktop,
   see the Windows 95 help.

Q: Why can't I play a compact disc through Windows 95's "My Computer"?

A: Windows 95 must have its CD Player installed before you can play CDs
   through My Computer. To make sure the Windows 95 CD Player is loaded:

   1.  Select Settings from the Start menu, then select Control Panel.
   2.  Double-click the Add/Remove Program icon.
   3.  Select the Windows Setup tab.
   4.  Select Multimedia.
   5.  Select the CD Player check box, then click OK.

Q: Why don't I hear any sound when playing a MIDI file with Windows 95's
   Media Player?

A: You won't hear any sound when playing a MIDI file if your MIDI drivers
   have not been configured for Mwave. To make sure that Mwave is prop-
   erly configured:

   1.  Select Settings from the Start menu.
   2.  Select the Control Panel.
   3.  Select Multimedia.  From the multimedia screen, select "MIDI".
       Select "Single instrument" and highlight "Mwave MIDI Synthesizer".

Q: Why do I receive an error message when I try to play an Mwave
   Synthesizer Samples .WAV file in an audio application?

A: The Mwave Synthesizer uses samples in the form of *.WAV files
   installed on the hard disk to play music.  These WAV files are
   intended solely for use by the synthesizer and are formatted correctly
   for this purpose.  However, if for some reason a user tries to use an
   audio application to play the *.WAV files individually, the applica-
   tion may respond with an error message.  This does not indicate a
   problem in using the files for their intended purpose.

Q: How can I prevent the noise in my 8 bit recordings?

A: An 8 bit recording is naturally noisy.  To reduce the noise level of
   your recording, use 16 bit recording.

Q: How do I get Sound Blaster games to run after a suspend/resume when it
   has been running with MIDI?

A: Stopping MIDI will not enable Sound Blaster games to run correctly.
   Instead, close and then reopen the Sound Blaster application.

Q: Sound Blaster games run after a suspend/resume but my Telephone
   Answering Machine (TAM) cannot receive calls.  How do I reactivate the
   TAM?

A: Close and then reopen the Sound Blaster application.

Q: How do I restore the sound to games such as DOOM or DOOM II running in
   a Windows 95 DOS session after a suspend/resume?

A: Close and then reopen the game application.

Q: Why do I hear pauses when I play an audio wave (.WAV) recording from a
   floppy diskette?

A: These pauses during playback occur due to the slower rate of data
   transfer from the diskette. To fix the problem, copy the wave (.WAV)
   file to your hard disk.

Q: Why does my .WAV file I just recorded sound "broken"?

A: "Broken" or discontinuous sound is often the result of either the
   slower data transfer rate from a floppy drive, or you recorded the
   .WAV file to a drive that is compressed (using DriveSpace,
   DoubleSpace, or Stacker). In both cases, the playback application
   cannot receive data fast enough and, as a result, you hear the gaps in
   the transaction.

   To fix this problem, you can:

   o   Record the .WAV file to a fixed disk (i.e., C: ).
   o   Lower the record rate to 22 KHz or 11 KHz, change to 8 bit, and/or
       change to mono sound. Most applications allow you to adjust these
       parameters, and less taxing record rates may solve the problem.
   o   If you use a disk compression program (such as DriveSpace,
       DoubleSpace, or Stacker), direct the recorded data to an uncom-
       pressed drive. This way, the computer can process the sound
       without taking the time to uncompress/compress the information.

   Refer to Section 5.2  Audio/MIDI Technical Notes for additional tech-
   nical information.

Q: Why don't I hear sounds from my game or CD when the Mwave Modem is
   also running?

A: Mwave manages the workload of the digital signal processor, the device
   that allows you to play sound, use telephony, etc. If you don't hear
   sounds from your DOS game or CD, it is likely that Mwave is using the
   modem to send a file or has set the modem to answer the telephone.

   Wait for these other tasks to finish. You should then hear the sounds
   from your game or CD.

Q: Why does the volume on 8 bit recordings seem softer than 16 bit
   recordings?

A: Most prerecorded 8 bit wave files, like those included with applica-
   tions or Windows, are compressed to improve their signal-to-noise
   (S/N) ratio.  These compressed files are much louder than the uncom-
   pressed audio (wave, synthesizers, MPEG) in the system.

   To compensate for loud prerecorded 8 bit audio, Mwave tasks reduce the
   playback level of all 8 bit recordings.  The volume reduction is done
   with 16 bit precision, so the S/N ratio is NOT reduced.  The reduced
   and compressed 8 bit audio plays slightly louder than typical uncom-
   pressed 16 bit audio, and slightly reduces the volume of uncompressed
   8 bit audio.

Q: What happens if I change the input source of the mixer during
   recording?

A: Changing the input source results in muting of the audio. If you inad-
   vertently do this, restart Windows to recover.

Q: How does FASTCFG affect audio play and record?

A: The audio play and record will not function if you select "Mic" as the
   input source.  If you select "None" as the input source, the input
   will function as "CD" or "Line."

Q: How do I stop feedback from occurring when I use my microphone?

A: Lower the peak levels for playback and record for your microphone.

   1.  Click Start, point to Programs, Mwave, and click Audio Control.
   2.  Click on the MIC button.
   3.  Click and drag the microphone (MIC) slide controls to a lower
       level.
   4.  Resume using the microphone.

   (Note:  When the play pushbutton is selected, make sure that the
   microphone check box is not selected.)

----------------------------------------------------------------------
3.4  FAQs about Mwave's Telephone Country Selection Utility
----------------------------------------------------------------------

Q: What is Country Selection?

A: The Mwave Telephone Country Selection program is used to set country
   specific parameters for Mwave telephony functions including Modem,
   FAX, speakerphone, and Telephone Answering Machine.  The Mwave tele-
   phony drivers use the Country selection information to permit reliable
   and safe connection to the appropriate telephone network.

      **********
       WARNING:    Improper selection of the telephone network may cause
      **********   unreliable operation.

----------------------------------------------------------------------
3.5  FAQs about Mwave's Sound Blaster Emulation
----------------------------------------------------------------------

Q: What sound card does Mwave emulate?

A: Mwave emulates a Sound Blaster 1.5 (SB) card.

See additional information in Section 5.3  Sound Blaster Technical Notes
in this file.

----------------------------------------------------------------------
3.6  FAQs about Mwave and Loading Windows 3.x or Windows 95
----------------------------------------------------------------------

Q: Why can't I open Windows after receiving the following message:

       "Mwave Warning:  Mwave has detected a memory condition that may
       adversely effect Windows operation.  Windows will not be started.
       Restarting your machine may solve this problem.  If this message
       displays again, read \MWW\README.TXT"

A: This message typically calls attention to memory resources used by
   Mwave and DOS "terminate and stay resident" (TSR) programs, such as
   DOSKEY. To avoid the warning message and start Windows, you can:

   o   Make sure that Mwave is loaded after the TSRs by verifying that
       the "CALL MWAVE START" statement in your AUTOEXEC.BAT file follows
       all calls to load TSR programs.

   For Windows 3.x:

   o   Restart your PC if you invoke a TSR before you launch Windows.
   o   Modify the MWW\MWAVE.INI file to start regardless of the TSRs you
       have loaded in memory. Add the line WINSTART=YES to the {MWAVE}

3.7  FAQs about Using Mwave and Other DOS Applications
----------------------------------------------------------------------

Q: What should I do if can't run a DOS application, such as a word
   processor, that does not use Mwave features (e.g. Mwave Modem, Mwave
   Games, etc.)?

A: Some DOS applications may not run if they try to use resources con-
   sumed by Mwave. You can run these applications after you turn off
   Mwave features. At the DOS prompt, type MWAVE OFF to turn off Mwave.
   To resume use of Mwave once you finish with your DOS application, type
   MWAVE ON at the DOS prompt or reboot your computer.

    To avoid the Catch-22 situation described below regarding a Prodigy
    error message, please follow these steps before installing the Mwave
    code upgrade.

    1.  Log onto Prodigy
    2.  Jump 144
    3.  Click on "SETUP for 14.4"
    4.  Proceed through this setup selecting phone numbers etc.
    5.  Prodigy will automatically download the latest set of modem
        initialization strings
    6.  Install Mwave Upgrade

    The following are related topics:

    -   Prodigy Error Message After Installing Mwave Upgrade

        Current ThinkPad users upgrading to new Mwave upgrade code may
        get a CT39 or similar error message the first time they log onto
        Prodigy.  These users must download the latest modem initializa-
        tion strings from Prodigy in order to work correctly.  This down-
        load is required only once.

        A Catch-22 situation exists if the user installs the Mwave
        upgrade without first downloading the latest initialization
        strings (a likely scenario) .  The user needs the latest initial-
        ization strings to sign on to Prodigy but must first sign on in
        order to download them.  Listed below are two procedures users
        can follow to extract themselves from this situation.

    -   After Installing Mwave Upgrade and Getting Error Message

        1.  From a DOS box, type ASSIST in the Prodigy subdirectory
        2.  Hit "CONTINUE" and let PRODIGY try to test the modem
        3.  When it fails, it will pop a "SELECT MODEM" dialog box
        4.  Pick "UNLISTED 9600/14400 (b)"
        5.  Prodigy will retry and succeed this time
        6.  Log onto Prodigy
        7.  Jump 144
        8.  Click on "SETUP for 14.4"
        9.  Proceed through this setup selecting phone numbers etc.
        10. Prodigy will automatically download the latest set of modem
            initialization strings
        11. Next Prodigy log on should be without trouble.

    -   After Installing Mwave Upgrade and Getting Error Message (Alter-
        nate)

        1.  From a DOS box, type ASSIST in the Prodigy subdirectory
        2.  Hit "CONTINUE" and let PRODIGY try to test the modem
        3.  When it fails, it will pop a "SELECT MODEM" dialog box
        4.  Pick "UNLISTED 9600/14400 (b)"
        5.  Prodigy will retry and succeed this time
        6.  Click SETUP (Communications Options) on the Prodigy Sign-On
            screen
        7.  Select "Dial the Prodigy Phone Directory" (bottom right radio
            button)
        8.  Let Prodigy dial
        9.  Reselect your primary and secondary phone numbers
        10. Prodigy will automatically download the latest modem initial-
            ization string
        11. RECONNECT to Prodigy and all should be well.

o   Microsoft Mail 3.2

    Microsoft Mail 3.2 fails to connect when using the Mwave modem.  The
    suggested fix from Microsoft is to add the line "exclusive=0" under
    the {SFSremote} heading in \WINDOWS\MSMAIL.INI.

o   Windows for Workgroups 3.11

    The Remote Access Support (RAS) doesn't recognize the connected
    response from the Mwave modem. The IBM Personal Computer Company
    (PCC) Bulletin Board Service (BBS) provides a MODEM.INF file with the
    correct Mwave information. You should obtain this file and add the
    information to the \WINDOWS\SYSTEM\MODEM.INF file.

o   Windows for Workgroups (WFW) and Communications Applications in
    Windows 3.x

    Some communications applications hang on the second attempt to use
    the COM port. This condition occurs because the SERIAL.386 driver
    provided with WFW 3.11 does not properly handle UART First In--First
    Out (FIFO) capabilities.

    To fix this problem, obtain the WG1001.EXE fix from Microsoft. (You
    may also find this file on the IBM ThinkPad Forum on CompuServe.) In
    some cases, you may need to replace WFW's \WINDOWS\SYSTEM\COMM.DRV
    with COMM.DRV from Windows 3.1 to completely solve the problem.

The following items provide specific information about the fax applica-
tions mentioned above.

o   Delrina's WinFax Pro version 4.0

    If you are installing WinFax Pro 4.0 as a new application, you may
    encounter the following questions and error messages.

    Under Windows 95, installation may stop and inform you of the
    detection of a Windows desktop other than "progman."  You will be
    instructed to exit Windows and use "progman" instead.  Do NOT discon-
    tinue the installation.  Select "Continue" and proceed.  You will
    also be given the opportunity to change the COM driver and FIFO
    parameters.  Select "No" when asked if you want the system to make
    these changes to the \WINDOWS\SYSTEM.INI file.

    The WinFax Pro 4.0 installation prompts you to test the Fax modem.

    -   If you select "Yes," the message "Unable to communicate with
        fax/modem - unknown device" appears.
    -   Select "No" and continue.
    -   From the Fax/Modem Setup screen:
        1.  Set the modem type to Class2
        2.  Select the proper COM port
        3.  Do not change the initialization strings
    -   The message "Setup cannot communicate with the fax device con-
        nected to your COM port.  Do you want to continue?" appears.
    -   Select "Yes."
    -   When asked if you want to make \WINDOWS\SYSTEM.INI file changes,
        select "No."

    The Mwave Fax modem is now properly installed.

o   Phoenix Technologies' Eclipse Fax version 6.0

    Using an editor (such as Notepad), modify the {MODEM} section of the
    \WINDOWS\E-FAX.INI file by changing "Priority FAX=1" to "Priority
    FAX=0"

    When you exit Eclipse, there is a short delay and the message "The
    Modem is not responding" appears.  Ignore this message.

o   Hayes's SmartCom Fax version 1.01B

    You must select the PCMCIA 144/144 FAX modem in the
    Utilities/Hardware configuration dialog box to use Mwave with this
    application.

o   Smith Micro's QuickLink II 1.4.3 and QuickLink Gold 1.2

    When started, QuickLink returns the error message: "Unable to ini-
    tialize modem!  Check modem and/or baud rate setting, then select
    OK."  Ignore this message and select OK.

    The main QuickLink application panel must be displayed in order to
    receive a Fax.

o   Sofnet's FaxWorks Pro version 3.0

    Using an editor (such as Notepad), modify the {MODEM} section of the
    \WINDOWS\FAXWORKS.INI file by changing "Priority FAX=1" to "Priority
    FAX=0"

    When you exit FaxWorks, there is a short delay and the message "Modem
    not responding" appears.  Ignore this message.

General Usage Note:  Many Fax applications offer a custom communications
(COM) driver that may improve Fax transmission speeds.  Mwave uses the
Windows default COM driver when testing these applications.  If a tested
application does not perform, verify that the Windows default COM driver
statement, "comm.drv=comm.drv", is in the {boot} section of the
\WINDOWS\SYSTEM.INI file.  (NOTE: You can use an editor such as Notepad.)

Problems may occur because an applications COM driver is not compatible
with other applications.  In addition, some applications will not give
you the opportunity to change a non-default COM driver, regardless of
compatibility.

----------------------------------------------------------------------
4.3  DOS FAX Applications
----------------------------------------------------------------------

Mwave Class 2 fax is compatible with the following DOS Fax applications:

o   Delrina's DOS Fax Lite version 3.0
o   Delrina's DOS Fax Pro version 2.0
o   Cheyenne's BitFax version 4.05A

The following items provide specific information about the fax applica-
tions mentioned above.

o   Delrina's DOS Fax Pro version 2.0

    The Mwave modem must be running before initializing and using DOS Fax
    Pro.

o   Cheyenne's BitFax version 4.05A

    Each time you start BitFax, send a fax before attempting to receive
    faxes.  This ensures that BitFax can receive Class 2 faxes from the
    Mwave modem.

Delrina's DOS Fax Lite version 2.00 is not currently compatible with
Mwave Class 2 Fax.

----------------------------------------------------------------------
4.4  Memory Problems with Windows and DOS TSRs
----------------------------------------------------------------------

Loading programs such as DOS TSRs (e.g. DOSKEY) in memory after Mwave
loads may result in a memory error condition and prevent Windows from
starting. There are three ways you can get past the message and start
Windows.

o   To start Windows in most general purpose situations:

    Load Mwave last, after all other items, for it to function properly.
    Check the contents of your AUTOEXEC.BAT file to make sure Mwave loads
    last:

    1.  Open the AUTOEXEC.BAT file with an editor.
    2.  Verify that "CALL MWAVE START" follows all calls to TSR programs.
    3.  Restart your computer.

o   To start Windows after invoking or using a DOS TSR:

    If you invoke certain programs (such as TSRs) in DOS before you start
    Windows, you may encounter memory errors. To avoid these memory prob-
    lems, you must restart your PC before launching Windows.

o   To override the problem and start Windows without unloading TSRs:

    In some situations, you may want to continue with Windows while the
    TSRs consume memory resources. If your PC has more than 8 MB of RAM,
    this should not pose a problem. If your PC has less than 8 MB of RAM,
    you may experience slower performance from Windows.

    In Windows 3.x you can bypass this memory condition by modifying the
    \MWW\MWAVE.INI file.  To accomplish this:

    1.  Open \MWW\MWAVE.INI in an editor.
    2.  Add the parameter WINSTART=YES in the {MWAVE} section.
    3.  Restart Windows.

    (Note: Windows may lose the use of extended memory if it loads while
    TSRs are present, which negatively affects Windows performance.  Make
    sure that you consider this possibility before editing the .INI.)

4.5  Recording Problems with TalkWorks** AudioRecorder
----------------------------------------------------------------------

When you use TalkWorks AudioRecorder with Mwave and select 8 kHz 8 bit
stereo for recording, a monoaural signal is recorded instead of the
intended stereo signal.

----------------------------------------------------------------------
4.6  Other Applications and Mwave
----------------------------------------------------------------------

o   Lotus Notes 3.x

    Lotus Notes 3.x does not properly recognize the Mwave modem. Lotus
    does not include an .MDM file that describes the Mwave commands and
    responses.

    To fix this problem, obtain a copy of the MWAVE.MDM file from the PCC
    BBS and add it to the \NOTES directory. Follow these steps:

    1.  Start Lotus Notes 3.x.
    2.  Select the modem configuration. The list of choices should now
        include the Mwave modem.
    3.  Choose the Mwave modem from the list.
    4.  Return to Notes and use as you usually would.

o   Windows 95 Volume Control

    The Mwave Audio Control and the Windows 95 Volume Control applica-
    tions are not synchronized.  Using both controls simultaneously
    results in incorrect settings.  In order to avoid this situation,
    operate only one audio controller.  Microsoft is investigating this
    Windows 95 device driver problem.

o   Windows 95 Phone Dialer

    ThinkPad does not support connection of the handset necessary for
    Windows 95's Phone Dialer.

This section provides additional technical information and support for
specific uses of Mwave functions and/or applications.

----------------------------------------------------------------------
5.1  Recommendations for Optimum Mwave Modem Performance
----------------------------------------------------------------------

IBM recommends the following settings or conditions for best performance
from your Mwave Modem:

o   For best throughput when sending or receiving data, select the
    highest-ranking available transfer protocol listed here.

    1.  ZMODEM
    2.  Ymodem-G
    3.  TEXT
    4.  ASCII
    5.  XMODEM (only as a last resort)

o   If you are operating in Windows 3.x, try to ensure that your communi-
    cation application fully utilizes the First In--First Out (FIFO)
    capabilities provided by Mwave.  Specifically, the application should
    fill the FIFO six (6) or more characters per interrupt during
    transmit.

o   You should enable Hardware Flow Control. Use the Hayes command AT\Q3.

o   Select a modem protocol from this list, with (1) providing the best
    performance, and (6) giving the worst.

        Protocol                   AT Commands use to get protocol
       ------------------------------------------------------------
               1. V.42 / V.42bis              AT\n7"H3
               2. MNP 1-4 / V.42bis           AT\n3"H3
               3. MNP 1-4 / MNP5              AT\n3"H0
               4. V42                         AT\n7"H0
               5. MNP1-4                      AT\n3%C0"H0
               6. non-error corrected         AT\n0

    Refer to the online help available in Mwave Modem for explanation of
    the AT commands required to use one of the above modem protocols.

o   Trouble Connecting at 28.8 kbps

    If you experience difficulties connecting at a modem speed of 28.8
    kbps to a particular number, or if you have trouble connecting to a
    particular modem rotary, try the following.

    -   If the connection is not made and the speaker is OFF:

        1.  Disable V.42 bis and MNP 5 using AT"H%C
        2.  Disable V.42 (AT\N3) or MNP 1-4 (AT\N5). You could also
            disable both with AT\N.

    -   If the connection is not made and the speaker remains on:

        1.  Reduce the maximum modem throughput using the AT commands
            ATS28=18 (for 26400 bps), ATS28=17 (24000 bps), ATS28=16
            (21600 bps), or ATS28=15 (19200 bps).
        2.  If you've tried step 1 and it still does not connect, use
            AT*TH8 to control the speed.

            Once you connect using the AT*TH8 command, remember to reset
            your modem using either AT&F (for factory defaults) or
            AT*TH4. If you forget to reset, your next calls will transmit
            at lower V.34 connection rates.

----------------------------------------------------------------------
5.2  Audio/MIDI Technical Notes
----------------------------------------------------------------------

o   Additional Memory Requirement for Complete MIDI Sample Set in Windows
    3.x

    The Mwave internal sampled sound synthesizer comes equipped with a
    complete General MIDI sample set. Depending on how extensively this
    capability is used, up to 3 MBytes of memory may be required.

    Here are some tips which may improve MIDI performance:

    -   Remove all RAM disks from your AUTOEXEC.BAT.

    -   Remove SMARTDRV from your AUTOEXEC.BAT or reduce the amount of
        memory allocated to the SMARTDRV cache.  The line in your
        AUTOEXEC.BAT should be: C:\WINDOWS\SMARTDRV.EXE 256 0

    -   Use the standard VGA video driver for Windows.  Run Windows
        System Setup from the Main Program Group, select Options and
        Change System Settings, then select the VGA Display driver.

o   Recording Audio

    Successful recording of audio Wave (.WAV) files depends on a variety
    of factors including processor speed, amount of free disk space, data
    fragmentation on the hard disk, and the type of application used.
    Some computers, particularly those with slower processors, either
    "hang" the system or produce recordings with gaps. These conditions
    occur when using high data rates, such as 44 KHz, which means the
    computer cannot keep up with the data transfer. If you attempt to
    record 44 KHz 16 bit stereo Wave files using a slower PC, you may
    encounter problems.

    Here are some tips that may improve recording:

    -   Erase unnecessary files from your hard disk.

    -   Lower the record rate to 22 KHz or 11 KHz, change to 8 bit,
        and/or change to mono sound. Most applications allow you to
        adjust these parameters.

    -   Use a Hard Disk Defragmentation program (usually included with
        Norton Utilities or Central Point PCTools) to create more contig-
        uous space on your drive. This keeps the slower PC from having to
        work too hard (and take too much time) looking for available disk
        space.

NOTE:  You can use the Disk Defragmentation utility.  Windows 95 includes
this utility under Start/Programs/Accessories/System Tools/Disk
Defragmenter.

    -   If you use a disk compression program (such as DriveSpace,
        DoubleSpace, or Stacker), direct the recorded data to the tempo-
        rary drive created by the compression program or to an uncom-
        pressed drive.  Again, the computer then can process the sound
        without taking the time to uncompress/compress the information.

NOTE:  Windows 95 users can find additional information on the disk com-
pression program DriveSpace under Start/Help/Index/DriveSpace.  DOS users
can find additional information on the disk compression program
DoubleSpace:  DOS 6.x users must type HELP DBLSPACE at the DOS prompt,
and IBM DOS 7.0 users type HELP STACKER at the DOS prompt.

    -   Use an alternative audio recording application. Audio programs
        use a variety of techniques to record and playback sound. Some
        may work well in situations where others fail to perform. For a
        basic test, try recording with the Windows Sound Recorder.

----------------------------------------------------------------------
5.3  Sound Blaster Technical Notes
----------------------------------------------------------------------

The "SET BLASTER=" Command

A few games require that DOS uses an environment variable to identify the
location of the sound hardware.  For such games, the following line is
added to the AUTOEXEC.BAT file during installation:

              SET BLASTER=A220 I5 D1

     This parameter...    Tells your game to...
     -----------------    --------------------------------------------
        A220              locate the sound hardware at address 220

        I5                use interrupt level 5

        D1                use DMA channel 1

    These are the default settings created during the installation of
    Mwave.

If you change these settings after installing a new peripheral card, the
"SET BLASTER=..." line must be changed accordingly.

----------------------------------------------------------------------
5.4  Notes about DOS Mode Support
----------------------------------------------------------------------

Windows 95 does not support Mwave functions if you attempt to access the
Startup Menu by pressing F8 during bootup and then selecting the Command
Prompt Only option.  Windows 95 supports normal Mwave DOS functions
(games, modem, class 2 fax) while in MS-DOS mode or in a Windows 95 DOS
session.

----------------------------------------------------------------------
5.5  Notes about Windows 95 Configuration
----------------------------------------------------------------------

Using the ThinkPad Features application to change the IRQ, DMA, etc.  may
not affect/alter Mwave's setup.  In order to be certain of the settings,
perform any setting changes through Windows 95.

----------------------------------------------------------------------
5.6  Notes About the Mwave Speaker Phone
----------------------------------------------------------------------

Some speaker phone volume controls malfunction at maximum output.  There-
fore, if the volume slider is at maximum volume and you cannot hear the
other party, lower the slider to 75% volume.
