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 Data/FAX Modem for Windows 2000
----------------------------------------------------------------------

Q: What FAX protocols are supported by the Mwave Data/FAX Modem.

A: Class 1 and Class 2 protocols are supported in USA, Canada and Japan.
   For the remainder of the Mwave supported countries, the FAX support
   is Class 2 only.

Q: Does the Mwave Data/FAX Modem support any Telephone Answering Machine
   or Speakerphone functions.

A: The Mwave Data/FAX Modem does not support these functions in Windows 2000.


Q: Does my preloaded Faxworks Application work in Windows 2000.

A: No. The Faxworks Application will no longer work with the Mwave Data/FAX
   Modem. Windows 2000 provides a FAX application that supports
   Class 1 and Class 2 and will work with the Mwave Data/FAX Modem.

----------------------------------------------------------------------
3.2  FAQs about Mwave Audio Features
----------------------------------------------------------------------

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

A: 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 compression programs
   such as DriveSpace, DoubleSpace, or Stacker). In both cases, the play-
   back 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 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 CD, it is likely that Mwave is using the modem to
   send a file.

   Wait for these other tasks to finish. You should then hear the sounds
   from your 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 do I stop feedback from occurring when I use my microphone?

A: Lower the peak levels for recording from your microphone.

   1.  Do one of the following:
       o   If you are using Windows 2000: From the Windows 2000 Start
           menu, select Programs-->Mwave-->Audio Control.
   2.  Select the MIC button.
   3.  Click and drag the microphone (MIC) slide controls to a lower
       level.
   4.  Resume using the microphone.

----------------------------------------------------------------------
3.3  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 (Modem and FAX).

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

======================================================================
4.0  COMPATIBILITY
======================================================================

Read through this section if you have any problems with a specific appli-
cation working with Mwave.

----------------------------------------------------------------------
4.1  Communications (Modem) Applications
----------------------------------------------------------------------

o   Connecting to Prodigy

    When attempting to use the Mwave Modem to connect to Prodigy using a
    2400 bps Y (Tymnet) connection, the connection fails.  Contact
    Prodigy support for assistance in solving this problem.

----------------------------------------------------------------------
4.2  Audio Applications
----------------------------------------------------------------------

The following are known audio problems.

o   When an audio mixer application is running (such as the Windows 2000
    Volume Control applet or the Mwave Audio Mixer), you may notice a
    delay of several seconds when you start playing a Wave (.WAV) file.
    This delay is especially noticeable if you have enabled system sounds
    and assigned a sound to a frequent event such as the opening of a
    pop-up menu.  Playback performance returns to normal after you close
    the mixer application.

o   When using some applications to record wave files (such as the
    Windows 2000 Sound Recorder applet), wave files recorded in the 8-bit
    mono format contain audible "clicks."  This problem does not occur
    when using 8-bit stereo, 16-bit mono, or 16-bit stereo formats.

5.0  OTHER TECHNICAL NOTES
======================================================================

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

o   You should enable Hardware Flow Control.  Use the Hayes command
    AT\Q3, or follow these steps in Windows 2000:

    1.  Do one of the following:

        -   If you are using Windows 2000:  From the Windows 2000 Start
            menu, choose Settings-->Control Panel.

    2.  Double-click the Ports icon.

    3.  Double-click the port for the modem, or select the port and
        choose the Settings button.

    4.  Click the scroll arrow to the right of the Flow Control box and
        select Hardware.

    5.  Choose the OK button.

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 V.34(speeds greater than 19.2 kbps)

    If you experience difficulties connecting at a modem speeds greater
    than 19.2 kbps to a particular number, or if you have trouble
    connecting to a particular modem, 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

    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.  You
    can improve MIDI performance by shutting down the modem or any active
    sound applications.

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.

    -   Be aware that mixer options such as Effects, QSound, and Tone
        affect the quality of playback.

    -   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.
