Additional information for Thinkpad Mwave users with DOS & Windows.         
    
 
MODEM                                                                      
-----                                                                      

1. The Mwave Modem must be open on the desktop in order for any
   Modem application to operate Correctly. Click on the MODEM  
   14,400 icon in the Mwave Thinkpad folder to open it. It can be
   minimized after it is opened. Be sure to close the modem 
   if you are going to perform other Mwave functions such as 
   FAX or TAM.                                                             

                                                                         
2. When installing a new modem application or reinstalling a pre-loaded 
   application, the modem type, baud rate and Com Port must be 
   properly defined in order for the application to work correctly 
   with the Mwave modem. 
                                                                           
   You should set the modem type as one of the following: 
      Mwave modem, or                      
      Hayes modem, or                                                      
      Hayes compatible modem, or 
      Hayes 2400B, or                                                
      Hayes Smartmodem 2400, or          
      Generic 2400 modem                                             
      other (here you will have to include your own AT command  
      initialization string.)                                              

   Set the Baud rate equal or higher than 14,400 (higher than 
   14,400 if 14,400 is not selectable, ie 19,200). This will               
   enable the full performance capability of the Mwave modem.               
                                                                        
   The Com port should be set to the appropriate port. This can be  
   displayed by clicking on the DSP icon in the Thinkpad Setup         
   folder. This was set at the factory to Com2.
                                                                           
   NOTE: If the Com port is changed then any application using 
   the Mwave Modem must be changed to reflect this new value.               
                                                                      
3. If after a suspend/resume, your communications program, such as  
   Procomm or WinCIM seems to not be able to communicate with the         
   modem, close the application and the modem and reopen them. 
                                                                         
4. Modem compatibility testing has revealed the need for the following 
   helpful tips for using Mwave modem:                                      
                                                                     
   A) Scenario: Mwave 14400 bps modem fails to connect to 2400 bps or 
      lower speed modem.                                                    
                                                                        
      Tip: It is difficult for V.32bis (14400 bps) modems to handshake 
           and get connections with a few older 2400 bps or slower      
           modems. If the Mwave 14400 bps modem is not connecting        
           with a 2400 bps modem, try setting the Mwave modem to           
           negotiate at 2400 bps or below.  There are several ways 
           to do this:                                                      
                                                                        
           Opt.1. Set S28=9 for maximum connect rate of 2400 bps or,  
                  Set S28=8 for maximum connect rate of 1200 bps or,       
                  Set S28=6 for maximum connect rate of 300 bps.        
                  The Com Port can be set to any rate at or above the 
                  connect rate in this case.                               
                                                                         
           Opt.2. With S28=0, set the Com Port speed to 2400 bps for 
                  maximum connect rate of 2400 bps or,         
                  With S28=0, set the Com Port speed to 1200 bps for 
                  maximum connect rate of 1200 bps or, 
                  With S28=0, set the Com Port speed to 300 bps for  
                  maximum connect rate of 300 bps.

           Opt.3  In the [FEATURES] section of the Mwave Modem ".INI" file, 
                  add a line which reads:  MNPPRELOAD=1
                  This file is: \WINDOWS\MWMWIN.INI for Windows
                                \MWD\BIN\MWMDOS.INI for DOS
                                                                          
   B) Scenario:  Mwave modem does not connect to a 300 bps or below modem.  
                                                                        
      Tips: 1. Set the Mwave modem for Bell 103 or CCITT V.21 mode to  
               match the other 300 bps modem.  This is done with the ATBn 
               command (where n=0 for CCITT, n=1 for Bell).  Note that   
               many modems do not support CCITT V.21 and the Mwave modem 
               would then need to be set Bell mode (ATB1).      
                                                                           
            2. Set S28=6 for connect rate of 300 bps or,             
               Set S28=5 for connect rate of 150 bps or,           
               Set S28=4 for connect rate of 134.5 bps or,              
               Set S28=3 for connect rate of 110 bps or,                 
               Set S28=2 for connect rate of 75 bps or,                    
               Set S28=1 for connect rate of 50 bps.                     
                                                                           
           3. We recommend you disable MNP and V.42 for 300 bps or below 
              since most modems do not support MNP at these rates.    
              Disable MNP with the AT\N0 command.               
                                                                           
   C) Scenario: Using DOS communication application to drive the Mwave  
                modem, and the receive data appears to get dropped when  
                being output to the screen.        
 
     Tip: Refer to the Windows SYSINI.WRI help file in the        
           \WINDOWS directory for COM settings in the SYSTEM.INI          
           file.  For DOS applications and 16550 UART support,            
           Windows recommends disabling ComxBuffers (ex:                
           Com2Buffers=0). NOTE:  Only use this for DOS                   
           communications applications.                              

  D) Scenario: My modem locks up when I use it with multiple Windows  
                applications.                                           
   
     Tip: Windows 3.1 Secrets by Brian Livingston, (ISBN 1-878058-43-6)
          provides the following tip:                                      
   
          Try installing your Mwave card in the first available    
          COM port. If you do not currently have a COM1 port,         
          install your Mwave card as COM1.  If you have a COM1     
          port and not a COM2 port, install the card as COM2, etc.         

5. Using the Power Management feature (Suspend/Resume) while the Mwave  
   Modem is connected to a remote modem can give unpredictable results.     
   To avoid these problems, terminate the telephone line connection  
   before using the Power Management features of the ThinkPad. 

6. Microsoft Mail 3.0 does not work with the Mwave modem. Microsoft is      
   currently working to solve the problem. 

7. The Mwave DOS modem is always reinitialized when loading Windows. Avoid  
   establishing a modem connection in DOS and then starting Windows.        
   Testing has found Novell's Netware Connect (this allows a PC to look     
   like a local node on the network via modem dial in) must be running in   
   DOS prior to starting Windows. This configuration is not supported. 
 
8. After starting the Mwave modem in DOS and then starting Windows, the     
   memory used by the DOS modem is not freed. After exiting Windows, the    
   DOS modem is automatically restored to its previous state. However,      
   while in Windows, the DOS modem is inactive but takes memory away from   
   Windows. It is therefore recommended that users issue "MWMODEM OFF"      
   prior to starting Windows.
 
9. When calling Prodigy on a 2400 phone number with a Y connect node        
   (tymnet) the modem connects and immediately hangs up. This problem is    
   under investigation with Prodigy.                      


CLASS 2 FAX 
-----------    

1. For all applications, the modem selected in the applications list of
   supported modems was "Generic Class 2" or equivalent.

2. The following Windows applications work with some restrictions:

   A) Sofnet's FaxWorks Pro version 3.0

      In the \WINDOWS\FAXWORKS.INI file, in the (MODEM) section, change the 
      line
             "Priority FAX=1" to
             "Priority FAX=0"  

   B) Delrina's  WinFax Lite 3.11, WinFax Pro 3.0 & 4.0 

      The WinFax setup routines do not correctly find the Mwave Class 2 Fax
      modem.  After instructing the Winfax installation to continue and 
      after correctly specifing the correct COM port, the application runs 
      as expected.

   C) Smith Micro's  QuickLink Message Center & QuickLink II

      Works unrealiably on slow machines (e.g. 25 Mhz 386 Machines).
      Does not support discrimination between Voice and Class 2 fax calls.

   D) AlphaNet Telecom's FollowFax

      FollowFax requires a class 2 fax application in order to operate.
      Although FollowFax is preinstalled on all Thinkpad 755CE and 755CD
      machines, a Class 2 application is not preinstalled.  The version of
      Sofnet's FaxWorks that is preinstalled in these ThinkPads is not     
      Class 2 compatible and will not work with FollowFax. Delrina's  
      WinFax Lite, WinFax Pro, and Trio's DataFax have been successfully  
      tested with the Mwave Class 2 upgrade and FollowFax.

3. The following DOS applications work with some restrictions:

   A) BIT Software's BitFax Version 4.05A

      Send and Manual Receive work reliably.  Automatic Receive appears to  
      be unreliable with the Mwave Class 2 upgrade at this time.

4. The following applications do not work with Mwave Class 2 at the current
   time.  Solutions are being researched and updates will be made as soon
   as possible.

      Microsoft's Windows for Workgroups Fax Version 3.11
      Sofnet's FaxWorks Pro Version 3.0
      Datastorm's ProComm Plus for Windows Fax Version 2.00
      Delrina's WinFax Lite Version 2.0
      BIT Software's BitFax for Windows Version 2.09D
      Delrina's DosFax Lite Version 2.00  (DOS application)

5. If a Class 2 Fax application is closed abnormally, such as after a 
   Windows GPF, a subsequently opened modem application like Procomm may 
   fail to work correctly. To avoid this situation, insure that either thru
   a modem application initialization string or thru manual operation, that
   an "ATZ" is executed and the modem application will work correctly.  


DISCRIMINATOR
-------------

1. Answering a phone call, by picking up the telephone, will not prevent    
   the PC from trying to detect if the event is a voice or FAX call and     
   then answering the call as well. It is recommended that users close the  
   discriminator before answering a call with the PC attached telephone.

2. User with 8514A displays will experience a font mismatch with the        
   discriminator status panel. This will be resolved in a future update.

SPEAKERPHONE
------------

1. Using the Power Management feature (Suspend/Resume) while using the
   speakerphone can prematurely terminate a telephone call. To avoid this
   problems, set the Power Management features from activating the suspend
   mode during the inactivity of keystoke inputs. 

 
AUDIO  
-----  
                                                                           
1. 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 3MBytes 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. 
                                                                           
2. Audio wave recording depends on a variety of factors including 
   the processor speed, the amount of free disk space, data                 
   fragmentation on the hard disk, and the application being used.
 
   Some computers, particularly those with slower processors   
   have been observed to hang or produce recordings with gaps 
   at high data rates such as 44KHz.  The reason for this is 
   that the machine cannot keep up with the data.                
   Attempting to record 44 KHz 16 bit stereo may prove to be 
   difficult on all but the fastest computers. 
  
   Here are some tips which may improve recording results:                  
                                                       
    - Erase unnecessary files from the hard disk.                           
                                              
    - Lower the record rate to 22KHz or 11KHz, change to 8 bit, and/or 
      change to mono.  The rate is selectable in certain applications. 
                                                                           
    - Use a defragmentation program to create a large contiguous 
      free region on your hard disk.                                        
                                 
    - If you have DoubleSpace or Stacker or some other disk compression  
      program installed on your hard disk, direct record data to the 
      temporary drive is created by each of these programs.            
      See the documentation for the particular hard disk compression       
      program you are running to see how to do this.  You can also         
      copy files to this disk to play back at high rate.
     
      Note to DOS users: Information on the disk compression program that 
      ships with 6.+ is available through the DOS help.  Type HELP in a DOS
      prompt and read the information on DBLSPACE.                         
                                                                          
     - Try an alternate audio recording application.  Audio programs are  
       implemented in a variety of ways.  Some implementations are better  
       suited for a particular scenario than others.  For example, try  
       recording with either the Windows Sound Recorder or the Mwave  
       Recorder.                        
                                                                           
3. If you are getting a message that no WAVE or MIDI device is            
   available, it is probably because you are already using all of  
   the processing power of the MWAVE DSP.  Try:                             
                                                                        
   A. Closing an application that uses the DSP such as:                    
         - a MIDI player or sequencer  
         - the MIDI port task if it is used in your MIDI mapper or
           application
         - a WAVE audio player or recorder 
         - CD audio playback.  To do this:  In the Mwave Thinkpad group,   
           double click on the Mwave Audio Control application. Then select
           "Options."  Select "Off" for Aux Source. Then click on "OK".
                  
  OR:                                                                      
             
   B. Select a synthesizer that consumes less DSP processing
      power.  To do this:  In the Mwave Thinkpad group,  
      double click on "Select Synthesizer."  Select a synthesizer 
      with less voices.  Click on OK.

4. When playing back an audio wave recording from a floppy diskette,
   there may be some pauses during playback.  This is due to
   caching of the incoming data from the diskette.  To alleviate
   the problem, copy the wave file to the hard disk. The Mwave Synthesizer  
   cannot be reinstalled via control panel.  
                                                                           
5. If you are running PC3270 for Windows, it is recommended that you 
   close your host session before using the Mwave synthesizer. 
   Alternately, you should stop playing the synthesizer when running 
   PC3270 for Windows. PC3270 for Windows and the MIDI synthesizer 
   will not run simultaneously. 
        
6. If you experience an error with an application utilizing the 
   Mwave MIDI Port, check to make sure Audio Mode is set to normal.  
   To do this: In the Mwave Audio Control application. Then select          
   "Options."  Select "Normal" for audio mode and "OK".

7. When opening the Windows Media Player, or changing the synth voice       
   selection, there is a 5 to 7 second delay caused by opening the Mwave    
   Discriminator. This will only occur on the first invocation of the Media
   Player after a Mwave install. Subsequent invocation will not exhibit     
   this behavior.
                                                                           
                                            
Mwave Telephone Country Selection Program 
----------------------------------------- 
                                                                           
1. The Mwave Telephone Country Selection program is used to tell your Mwave 
   telephone applications include Modem, FAX, SpeakerPhone, and Telephone  
   Answering Machine.  The applications use the Country selection 
   information to permit reliable and safe connection to the telephone  
   network. 
                                                                           
   WARNING:  Improper selection of the telephone network may cause 
             unreliable operation. 
                                                                           
2. A Country Selection program is provided for Windows and DOS. The Windows 
   program can be executed by using the Country Selection icon in the 
   Mwave folder. In DOS type Country at the command prompt.                
    
   For Windows, the data field at the top of the window shows the currently 
   selected telephone network.  A different network may be selected by 
   positioning the cursor on the new selection and clicking on the entry 
   and then clicking on the OK button.  The program terminates when the 
   selection is completed.  A selection may be cancelled by pressing the  
   CANCEL button.  The program terminates when CANCEL is pressed.
                                                                           
3. If a country is not listed, see your IBM representative for help in  
   getting support for that country.  
                                                                           
4. If any telephony application is open, a change to the country  
   selection will not take effect until the modem is shut 
   down and restarted. This tool is intended as a setup utility to  
   establish the country of operation. It should not be executed with 
   the modem open. Upon completion of the utility, Windows should be
   exited and restarted.

5. When the "Country Selection" is modified in DOS, the
   selection is not reflected in Windows.  Likewise, when the country
   selection is modified in Windows, it is not reflected in DOS.
   To avoid this issue, a user must change the country selection 
   in both environments in order for Modem, Fax or TAM applications
   to work correctly in both Windows and DOS.
 
                                                                           
SOUND BLASTER EMULATION 
-----------------------  
                                                                           
1. Your Mwave hardware emulates a Sound Blaster 1.5 card.
                                                                           
2. If your game indicates that it cannot detect Sound Blaster interrupts  
   (or it seems to halt at the end of speech passages), AND you are  
   configured for an interrupt other than IRQ 7, try reconfiguring 
   the Sound Blaster settings for IRQ 7 using the supplied configuration 
   utility Make sure that your game is also setup to look for IRQ 7 
   and play again. Please refer to the documentation that came with 
   your Mwave hardware for instructions on changing the Sound Blaster 
   configuration.  
                                                                           
3. A few games require that an environment variable be defined which  
   will point the game to the location of the sound hardware. 
   For such games, the following line is added to the AUTOEXEC.BAT: 
                                                                           
             SET BLASTER=A220 I5 D1 T1                                     
                                                                           
  In this line, "A220" tells your game that sound hardware can be 
  found at address 220.  Similarly, "I5" and "D1" tell the game to  
  use interrupt level 5 and DMA channel 1.  These are the default 
  settings that were used when your Mwave system was installed. 
  The T1 tells the game that a Sound Blaster 1.5 is being emulated.
  If a game has been initialized with other settings, the 
  "SET BLASTER=..." line must be changed accordingly.
