Additional information for Thinkpad Mwave users with DOS                        
                                                                                
                                                                                
                                                                                
MODEM                                                                           
-----                                                                           
                                                                                
1. When setting up a communications application to work 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                                                 
      other (here you will have to include your own AT command                  
      initialization string.)                                                   
                                                                                
2. If after a suspend/resume, your communications program, such as              
   Procomm or other communication program, seems to not be able to              
   communicate with the modem, close the modem and application and              
   reopen them.                                                                 
                                                                                
3. 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.                              
                                                                                
                                                                                
   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.                              
                                                                                
                                                                                
4. Various configurations in CONFIG.SYS have been identified as                 
   causing a hang when loading the DOS modem.  The problem                      
   configurations are when a memory manager, (i.e.  EMM386),                    
   is managing upper memory and the "DOS=UMB" is not set.  The                  
   thing to do is always tell DOS to check for an upper memory                  
   manager (DOS=UMB). If the memory manager is not used, then the               
   option will have no effect. This is what the DOS Mwave                       
   installation program will do.                                                
                                                                                
   The one known exception is when RAMBOOST from IBM DOS 6.X                    
   is being used. RAMBOOST will not run when DOS=UMB is included        OOST    
   in the DOS= statement. If RAMBOOST is added to CONFIG.SYS,                   
   the UMB option should be removed from the DOS= statement.                    
                                                                                
5. If Windows is used after MWMODEM OFF is issued, Windows will fail            
   upon exiting. If the DOS modem has been used prior to entering               
   Windows, the DOS modem should be left ON or turned back ON before            
   entering Windows.                                                            
                                                                                
Mwave Telephone Network Selection Program                                       
-----------------------------------------                                       
                                                                                
The Mwave Telephone Network Selection program is used to tell your Mwave        
telephone applications what telephone network you are using.  The Mwave         
telephone applications refer to the modem. The applications use the             
Network selection information to permit reliable and safe connection            
to the telephone network.                                                       
                                                                                
WARNING:  Improper selection of the telephone network may cause                 
          unreliable operation.                                                 
                                                                                
A Network Selection program is provided for DOS. To execute this                
utility, type "COUNTRY" at the DOS prompt.                                      
                                                                                
   The currently selected telephone network is highlighted.  A different        
   network may be selected by using the up and down cursor keys to              
   highlight the desired country and then pressing "Enter".  The program        
   terminates when the selection is completed.  A selection may be              
   canceled by pressing the "Esc" key.                                          
                                                                                
If a country is not listed, see your IBM representative for help in             
getting support for that country.                                               
                                                                                
If any telephony application is open, a change to the country                   
selection will not take effect until the function 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, DOS should be                   
rebooted.                                                                       
                                                                                
SOUND BLASTER EMULATION                                                         
-----------------------                                                         
                                                                                
1. Your Mwave hardware emulates a Sound Blaster 1.5 card.                       
                                                                                
   If you are playing a game from a CD-ROM which plays audio directly           
   from the CD, use the following command to enable Sound Blaster               
   emulation AND the line-in/CD audio:                                          
                                                                                
        MWGAMES ON CD                                                           
                                                                                
   If you are using an external CD-ROM, you will have to connect the            
   analog (or headset) output of the CD player to the "line-in"                 
   connector on Mwave.                                                          
                                                                                
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 hard ware 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 you have changed these settings, the "SET BLASTER=..." line               
   must be changed accordingly.                                                 
                                                                                
                                                                                
4. If MWGAMES is started, then stop it before starting MWModem by               
   entering MWGAMES OFF. If this is not done, the modem will be                 
   started anyway and games will be disabled.                                   
                                                                                
5. The SUSPEND function does not operate when MWGAMES is on.                    
                                                                                
6. If games is loaded, Windows is started and exited, games will no             
   longer be operational.                                                       
                                                                                
General                                                                         
-------                                                                         
                                                                                
1. Execution of MWGAMES or MWMODEM from the directory where Windows             
   is loaded (usually \WINDOWS) will give unpredictable results. Switch         
   to another directory or the root directory before running MWMODEM            
   or MWGAMES.                                                                  
                                                                                
2. A new command MWMIDI has been added. Running MIDI should not be              
   done if either games or the modem are running. To run MIDI, issue            
   the command: MWMIDI ON. When finished running MIDI, issue the                
   command: MWMIDI OFF. Running with MIDI turned off will reduce the            
   power consumption in the Thinkpad.
