TP 755,760,765 - Installation and FAQ's On MWave For Windows NT
Applicable to: World-Wide
Applicable Systems:
TP 755CE/CSE/CD/CV/CDV/CX, 760C/CD/E/ED/XD, 765D
Service Information:
If you are running an earlier version of NT Mwave, you must first Uninstall it (using the Mwave Uninstall icon) before installing this version.
Please be sure to install the MIDI samples before running any MIDI applications. Note that this is a separate installation done after the Mwave installation. Prior to using the Mwave modem, you must configure it (using the NT ThinkPad SetUp program) and then enable the appropriate COM port via the Windows NT Control Panel. (See README.TXT for details.)
Before installing Mwave on your NT-based Thinkpad, assure that the DSP is not disabled. You can check the status of the DSP (and enable it if necessary) using the ThinkPad Setup program (for ThinkPad 755 computers) or ThinkPad Features program (for Thinkpad 760 computers). Also, do not disable the DSP on an NT-based Thinkpad on which Mwave drivers are installed. An NT-based Thinkpad on which Mwave drivers are installed will not boot if the DSP is disabled.
For Mwave-enabled Thinkpads on which the DSP has been mistakenly disabled, recovery is possible using the following procedure:
1. Power on the Thinkpad while pressing F1.
2. Release F1 when the system emits a series of beeps.
3. When the Easy-Setup Screen appears, select Config, Initialize, OK, Exit, Restart, OK.
The following known limitations exist in this version:
1. Recordings w/ 8 bit mono made with Sound Recorder include extraneous clicks.
2. Some games utilizing concurrent MIDI and Wave operate unpredictably.
3. Do not select DMA Channel 6 for the Mwave DSP (via ThinkPad Setup).
4. On an auto-answered call, the modem will sometimes go back off-hook if the remote computer initiates the hang-up.
5. Using Media Player, if auto-repeat is selected, some MIDI files will hang the application on the first repeat cycle. For these files, clicking on rewind also causes the hang.
6. The Audio Control Help is incorrect primarily with regard to its reference to Audio/Image Synch and Options buttons which do not exist in the NT Audio Control application.
7. On a TP760CD, you may hear an audio hiss while the NT is doing a soft boot (i.e. not after a power-on).

Question:
What should I do if I answer an incoming phone call with the handset and then discover that the all is a fax or modem transmission?
Answer:
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.
Question:
What settings do I need to use when I install communications software (such as HyperTerminal)?
Answer:
Your commmunications software requires that you provide a modem type, a communications speed (the number of bits per second to be transmitted between the communications application and the modem), and the COM port to which the modem is attached.
- Modem Type
The following list ranks modem types, starting with the most preferred setting. Select the highest ranking setting available with your communications software.
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 type of 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.
- Communications Speed
The communications speed you specify depends on whether or not your modem will be using data compression. Most communications software applications provide a means (usually a checkbox) for you to enable or disable modem data compression.
- If you have chosen to enable modem data compression, you can specify a communications speed that is up to four times the actual baud rate that the modem will be using. For example, if the modem will be communicating at 28,800 bps, specify 115,200 bps, or the maximum setting offered by your communications software.
- If you have chosen to disable modem data compression, specify a communications speed equal to the baud rate of the modem connection.
- COM Port
Specify the same COM port that you selected when setting up the modem.
Question:
What can I do if my 300 baud modem connections are unreliable?
Answer:
Use the next higher setting (or baud rate) and try again. It is recommended that you use the highest possible setting of your Mwave Modem.
Question:
What port speed should I use when I connect my modem at 2400 bps?
Answer:
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.
Question:
What host application transfer protocol is recommended for best Mwave Modem performance?
Answer:
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.
3.2 FAQs about Mwave FAX Capabilities:
Question:
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?
Answer:
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.
Question:
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?
Answer:
See first Q & A in the above section, FAQs About the Mwave Modem.
3.3 FAQs about Mwave Audio Features:
Question:
Why do I receive an error message when I try to play an Mwave Synthesizer Samples .WAV file in an audio application?
Answer:
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 application may respond with an error message. This does not indicate a problem in using the files for their intended purpose.
Question:
Why do I hear pauses when I play an audio wave (.WAV) recording from a floppy diskette?
Answer:
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.
Question:
Why does my .WAV file I just recorded sound "broken"?
Answer:
"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:
- Record the .WAV file to a fixed disk (i.e., C: ).
- 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.
- If you use a disk compression program (such as DriveSpace, 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 technical information.
Question:
Why don't I hear sounds from my CD when the Mwave Modem is also running?
Answer:
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 or has set the modem to answer the telephone.
Wait for these other tasks to finish. You should then hear the sounds from your CD.
Question:
Why does the volume on 8 bit recordings seem softer than 16 bit recordings?
Answer:
Most prerecorded 8 bit wave files, like those included with applications or Windows, are compressed to improve their signal-to-noise (S/N) ratio. These compressed files are much louder than the uncompressed 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 uncompressed 16 bit audio, and slightly reduces the volume of uncompressed 8 bit audio.
Question:
What happens if I change the input source of the mixer during recording?
Answer:
Changing the input source results in muting of the audio. If you inadvertently do this, restart Windows to recover.
Question:
How do I stop feedback from occurring when I use my microphone?
Answer:
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:
Question:
What is Country Selection?
Answer:
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.
3.5 FAQs about Power Management with Windows NT:
Question:
How do I prevent termination of Mwave functions when using Power Management on my ThinkPad?
Answer:
If your computer enters suspend mode or hibernation mode while in the Microsoft Windows NT environment, the Mwave system will not be available once the computer resumes normal operation. In order to recover, you will need to shut down and restart the computer. To avoid this situation, we recommend disabling the suspend and hibernation power-saving features for Windows NT.
In order to use or disable Power Management features, you must first have installed the ThinkPad Features Program for Windows NT from the Utility Diskette.
Once installed, follow these steps to prevent your computer from entering suspend mode or hibernation mode during Windows NT operation:
1. In the ThinkPad window, double-click the Power icon.
2. In the Power dialog box, choose the More... button.
3. In the Suspend/Resume options box, do the following:
- To disable suspend mode, select the Will Not Suspend Even If LCD Is Closed check box.
In the Windows NT environment, this setting blocks suspend mode not only when the LCD display screen is closed but under ANY condition that normally causes the computer to enter suspend mode.
- To disable hibernation mode, choose the Disable Hibernation button. If you see an Enable Hibernation button, instead of a Disable Hibernation button, it means that hibernation is already disabled.
4. Choose the OK button.
5. To make the ch anges effective, shut down and restart Windows NT.
Question:
Why does my system enter standby mode instead of suspend mode when I choose the suspend icon in the Fuel window?
Answer:
In the Windows NT environment, entering suspend mode causes the Mwavem system to be disabled. To avoid this situation and still conserve some power, the suspend icon in the Fuel window was redefined to cause the computer to enter standby mode rather than suspend mode. Standby mode does not disable the Mwave system.

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 Mode m Performance:
IBM recommends the following settings or conditions for best performance from your Mwave Modem:
- 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)
- If you are operating in Windows NT, try to ensure that your communication 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. In Windows NT, you can use an enhanced COM port driver, such as TurboCom or KingCom, that fully utilizes the FIFO capabilities.
- You should enable Hardware Flow Control.
Use the Hayes command AT\Q3, or follow these steps in Windows NT:
1. In the Main group, double-click the Control Panel icon. Then double-click the Ports icon.
2. Double-click the port for the modem, or select the port and choose the Settings button.
3. Click the scroll arrow to the right of the Flow Control box and select Hardware.
4. Choose the OK button.
- Select a modem protocol from this list, with (1) providing the best performance, and (6) giving the worst.
Protocol AT Commands use to get protocol1. V.42 / V.42bis AT\n7"H32. MNP 1-4 / V.42bis AT\n3"H33. MNP 1-4 / MNP5 AT\n3"H04. V42 AT\n7"H05. MNP1-4 AT\n3%C0"H06. 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.
- 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:
- 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.
- 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.
