2.0 FREQUENTLY-ASKED QUESTIONS (FAQs)
======================================================================
This section contains answers to questions about certain features and
capabilities provided by Mwave applications.
----------------------------------------------------------------------
2.1 FAQs about the Mwave Modem
----------------------------------------------------------------------
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 async 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. Ymodem-G
3. TEXT
4. ASCII
5. XMODEM (only as a last resort)
For more information, see Section 5.1 Recommendations for Optimum
Mwave Modem Performance.
----------------------------------------------------------------------
2.2 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.
----------------------------------------------------------------------
2.3 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 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.
----------------------------------------------------------------------
2.4 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 .MID file with Windows 95's
Media Player?
A: You won't hear any sound when playing a MIDI (.MID) file if your MIDI
drivers have not been configured for Mwave. To make sure that Mwave is
properly 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 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 DOOM or DOOM II games running in a
Windows 95 DOS session after a suspend/resume?
A: Close and then reopen the DOOM or DOOM II 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 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 DoubleSpace or
Stacker), direct the recorded data to an uncompressed 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, most likely Mwave is using the modem
to send a file or set 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: The signal-to-noise (S/N) ratio is not as good for 8 bit Wave files.
This occurs because manufacturers increase the amplitude (loudness) of
their sounds in order to compensate for naturally occurring noise.
To compensate for this volume decrease while maintaining the S/N
ratio, lower the 8 bit playback amplitude.
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: Will the "pop" sound I hear when I press the record button while
recording from a CD be on my recording?
A: No.
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. Open Mwave Audio Control from the Mwave program group.
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.)
----------------------------------------------------------------------
2.5 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.
----------------------------------------------------------------------
2.6 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.
Q: Why does my DOS game indicate that it "cannot detect Sound Blaster
interrupts?" -and-
Q: Why does my DOS game seem to stop at the end of playing speech pas-
sages?
A: (To both questions) The problem may result from a configuration of
Mwave that uses an interrupt other than IRQ 5. This may happen if you
install another card in your computer. To resolve the problem:
1. Use the Mwave Configuration Utility to make sure Mwave is config-
ured to use the proper IRQ setting (the installation default is
5).
2. Make sure your game is set to look for a sound card at the same
IRQ location as specified in the Configuration Utility. (If you
maintain the default, the value should also be 5).
3. Restart the DOS game.
----------------------------------------------------------------------
2.7 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.
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}
section of MWAVE.INI. (Note: If you choose this option, Windows
will lose the use of this extended memory which may affect per-
formance.)
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.

- Select "No" and continue.
- From the Fax/Modem Setup screen:
1. Select the proper COM port
2. Set the modem type to Class2
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"

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
app does not perform, verify that the Windows default COM driver state-
ment, "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.

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. DOSKEYS) 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 in 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 order to
bypass this memory condition, you must modify 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 Other Applications and Mwave
----------------------------------------------------------------------
o Lotus Notes
Lotus Notes 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.
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 Windows 95 Volume Control and the Mwave Audio 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).
o Wing Commander III
The Wing Commander III game hangs intermittently due to an improper
DOS configuration. Modify your AUTOEXEC.BAT and CONFIG.SYS files as
shown below.
Make sure you include the following in your AUTOEXEC.BAT:
SET MWPATH=C:\MWW\MANAGER;C:\MWW\GAMES
SET MWROOT=C:\MWW
LOADHIGH C:\path\MOUSE.COM /Y (* your mouse driver *)
LOADHIGH C:\path\SHARE.EXE
SET BLASTER=A220 I7 D1 T1
Make sure you include the following in your CONFIG.SYS file:
DEVICE=C:\DOS\HIMEM.SYS
DOS=HIGH, UMB
FILES=30
BUFFER=30

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. Ymodem-G
3. TEXT
4. ASCII
5. XMODEM (only as a last resort)
o Try to ensure that your communication application fully utilizes the
First In--First Out (FIFO) capabilities provided by Mwave. Specif-
ically, the application should fill the FIFO six (6) or more charac-
ters per interrupt during transmit. For native DOS, HyperAccess COM
driver supports this action well. Windows 95 exploits the FIFO capa-
bilities without additional utilities. If you experience CRC errors
using the Mwave Modem, edit the SYSTEM.INI file, go to the (386Enh)
heading, and make sure the statement "COMxFIFO=1" is present (where x
is the COM port number).
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
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
The Mwave internal sampled sound synthesizer comes equipped with a
complete General MIDI sample set. Depending on how extensive this
capability is used, up to 3 MBytes of virtual 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
Recording audio Wave (.WAV) files depends on a variety of factors
including processor speed, amount of free disk space, data fragmenta-
tion on the hard disk, and the type of application used. Some com-
puters, 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 which 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 DoubleSpace or
Stacker), direct the recorded data to the temporary drive created
by the compression program or to an uncompressed drive. Again,
the computer then can process the sound without taking the time
to uncompress/compress the information.
NOTE: DOS users can find additional information on the disk com-
pression 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.
Windows 95 users can find additional information on the disk com-
pression program DriveSpace under Start/Help/Index/DriveSpace.
- 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.
One known exception to this scenario occurs in those systems that use
RAMBOOST in IBM DOS 6.x. RAMBOOST does not run when DOS=UMB is
included. To solve this problem, simply remove DOS=UMB from
CONFIG.SYS if you add RAMBOOST.
NOTE: RAMBOOST in IBM DOS 7.x is not currently compatible with Mwave.
The DOS=UMB statement in the CONFIG.SYS does not affect its compat-
ibility.
----------------------------------------------------------------------
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 Option 6
(Command Prompt Only). 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 Duplicate Drivers After Mwave Re-Installation
----------------------------------------------------------------------
Re-installation of Mwave to Windows 95 results in duplicate driver names
in the Multimedia Properties window. To remove these duplicate drivers:
1. Double-click the Multimedia icon in the Control Panel
2. Click the Advanced folder
3. Click the Media Control Drivers icon
4. Double-click the duplicate driver
5. Select Remove
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
