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 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: What is the transmission speed for Mwave Voice Over Data?
A: Mwave Voice Over Data is limited to 14.4 kbps.
Q: Why don't I hear modem sounds when I run the Microsoft Hardware
Compatibility 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: Why am I unable to telegame from a Windows 95 DOS session?
A: Telegaming in a Windows 95 DOS session requires a limited modem speed
of 14.4 kbps (V.32) and the modem default speed is 28.8 kbps. To
enable telegaming within a DOS session, set the modem speed to 14.4
kbps. To change the modem speed:
o Open the Mwave Modem.
o Click Options.
o Click Settings.
o Select 14400 (V.32 bis).
o Click OK.
NOTE: If the options in the Settings window are greyed-out, your
modem is connected; it must be disconnected for you to change the
modem speed.
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 1 (If your mouse is assigned this port,
use 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
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.
----------------------------------------------------------------------
3.3 FAQs about Mwave's Speaker Phone Capabilities
----------------------------------------------------------------------
Q: How do I prevent the speaker phone from terminating a telephone call
when my computer is set to automatically suspend after a period of
time with no keyboard activity?
A: To avoid having your telephone calls terminated when your computer
uses the Suspend/Resume Power Management feature, double-click the
Power icon in the Setup group Start/Settings/Control Panel to choose a
setup that does not include activation of the suspend mode when you
don't use the mouse or keyboard.
Q: When the Phoenix Message Center records an incoming call, how do I
prevent it from appending a dial tone to the end of the message?
A: The Phoenix Message Center's answering system requests that each
caller ends his/her message by pressing the "#" key before hanging up.
The calls you receive with "appended dial tones" occur when the caller
does not press #.
----------------------------------------------------------------------
3.4 FAQs about Mwave Audio Features
----------------------------------------------------------------------
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 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: Why doesn't the sound playback when I make a mono recording?
A: Mono recordings often record on only one stereo channel. Therefore,
make sure the balance sliders are at the center setting when recording
and replaying.
Q: What should I do when I receive a "WinDAT error" when I try to play or
record a .WAV file through AudioStation?
A: The AudioStation Mixer cannot handle Wave (.WAV) files. You can use
the Windows 95 Media Player for Wave playback or Windows 95's Sound
Recorder for both playback and record.
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: How do I control the sound in DOS games such as DOOM and Descent?
A: The Windows 95's Volume Control application controls the games sound
levels when played from a DOS session in Windows 95. When Mwave is
configured for Sound Blaster, control the volume with the AUX MIDI
Volume Control slider. When configured for General MIDI, both the
Master Volume and MIDI Play Out sliders control the volume. When
playing these games from native DOS, the sounds must be controlled
through the game application.
Q: How do I enable both Sound Blaster music and sounds in games such as
DOOM II telegaming in Windows 95 DOS-mode?
A: You must change the Mwave modem setting to V.32bis (14,400). To
change the setting:
1. Click START
2. Point to PROGRAMS and then MWAVE
3. Click Mwave Modem
4. Click OPTIONS on the menu bar and then SETTINGS...
5. Click 14400 (V.32bis)
6. Click OK
Q: Why am I unable to telegame?
A: When audio mixer options are selected, they consume the DSP resources
necessary to telegame, even when the mixer is off. Therefore, to
enable telegaming you must disable the mixer options such as Effects
and Qsound.
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 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 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 do I stop feedback from occurring when I use my microphone?
A: Lower the peak levels for playback and record for your microphone.
1. From the Windows 95 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.
(Note: When the play pushbutton is selected, make sure that the
microphone check box is not selected.)
----------------------------------------------------------------------
3.5 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.
----------------------------------------------------------------------
3.6 FAQs about Mwave's Sound Blaster Emulation
----------------------------------------------------------------------
Q: What sound card does Mwave emulate?
A: Mwave emulates both a Sound Blaster 1.5 (SB) card and a Sound Blaster
Pro (SB Pro) card.
See additional information in Section 5.3 Sound Blaster Technical Notes
in this file.
----------------------------------------------------------------------
3.7 FAQs about Mwave and Loading 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. In addition, the "CALL MWAVE
START" statement must precede the lines that call HWCHECK and
PS1START.BAT.
For additional information on the memory error condition message you
receive when starting Windows, see Section 4.4 Memory Problems with
Windows and DOS TSRs.

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:

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.
NOTE: The Terminate and Stay Resident Programs (TSRs), added to the
AUTOEXEC.BAT by Delrina's DOS Fax Pro installation, can cause con-
flicts in Mwave's ability to send and receive faxes.
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.
Also, make sure "CALL MWAVE START" precedes the statements that
call HWCHECK and PS1START.BAT.
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.
----------------------------------------------------------------------
4.5 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
In order to talk through Windows 95's Phone Dialer with Mwave, you
must attach a handset via the splitter plug (shipped with the Mwave
adapter).

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.
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 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 the Mwave Modem
----------------------------------------------------------------------
o CONFIG.SYS and the Mwave Modem
Certain configurations of memory managers defined in CONFIG.SYS may
cause the system to "hang" when loading the DOS modem. This condition
typically occurs when a memory manager tries to manage upper memory
and "DOS=UMB" is not set.
The solution is to always have DOS check for an upper memory manager
by including DOS=UMB in the CONFIG.SYS file. If DOS uses no memory
manager, this option has no effect. The DOS Mwave installation auto-
matically adds this line to your CONFIG.SYS file.
o V.23/Minitel Modem Connection
Mwave supports V.23 for modem connection to the Minitel network in
France only. V.23 is NOT supported in other countries.
To use V.23 with your modem application, issue the following AT
commands:
- AT+MS=3 to start a V.23 session
- AT&F to end your V.23 session
In order to use V.23, you must set your communications application to
the following settings:
- 7 bit even parity
- 1 stop bit
When you start a V.23 modem session, you are limited to V.23 modem
calls. However, Mwave still responds with the highest response
speed, up to V.34.
----------------------------------------------------------------------
5.5 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.
----------------------------------------------------------------------
5.6 Notes about Windows 95 Games
----------------------------------------------------------------------
If you are playing games that are made by Humongous and experience no
sound you will need to go to the Windows Mixer and un-mute the Wave
Phone Mute button. When you are done playing the game re-mute the Wave
Phone Mute button.
If you are playing games from Electronic Arts( NHL 97, Triple Play 97 ect...)
you may experience blank screen between events lasting 30 to 40 seconds.
This has been observed on machines that use the SIS 6205 video chipset.
If you are playing a game called Diablo from Blizzard and experience no
sound you will need to download and install the patch from the Diablo
bulletin board.
