SUPPORT IBM Bulletin Board (PCC BBS) Driver upgrades including WIN-OS/2, when available, can be obtained through the IBM Personal Computer Company Bulletin Board System. The phone number for this system is (919) 517-0001. Please note that upgrades may come in different forms such as patches to the main software or a whole new software package. Therefore, we suggest you back up your software before you attempt to update. 2. INSTALLATION 2.1 SWITCH AND JUMPER SELECTIONS * You must ensure that the ALL jumper settings on your DSP modem match the settings specified on the DSP modem configuration screen when running the verification program. If the settings do not agree, your system may hang (lock up) when you execute the basic or advanced tests. Furthermore the card will not function. 2.2 INSTALLATION OF DRIVERS * Refer to the user's guide 'Quick Installation' and follow the promptings of the install program. Since the DSP Modem has undergone several improvements to it's functions, and since there are numerous upgrades to follow, the user's guide detailed installation procedure is out of date. Please ignore 'Installing the DSP Modem Support Drivers' chapter under 'DSP Modem Support Drivers', instead follow the promptings of the install program. NOTE: This applies to older 'IBM V.32bis DSP Data/Fax Modem' user's guide only. * Uninstall (remove) ALL drivers prior to doing a selective install. You MUST remove ALL drivers and run install if the switches or jumpers on the card have changed. Unistall, of course, is done by choosing the unistall option presented when the setup program is run from diskette1 of the 3 diskette installation set. While in setup, please ensure that the settings presented by the install program match that of the card. This will ensure that the factory defaults (the actual settings) correspond to what is published in the user's guide. * Be sure to store your personal files in your own directory; For instance C:\MY_MWW. The setup program removes ALL files and directories while removing (uninstalling) the DSP modem drivers! * The install program removes all drivers from memory prior to entering the install menu. If the user should choose to CANCEL during installation, then be sure to exit and reenter Windows(tm) so as to install the drivers in memory. 2.3 COMPATIBILITY * Compatibility testing has revealed the following information relative to the DSP modem's proper operation in these systems, or with these system configurations: Tandy 2500 SX The I/O Ready jumper (J5), must be set to the Alternate position. IBM PS/ValuePoint P60/D The DMA level setting jumpers (J1,J2) must be set to level 0. Communications port COM4, the factory default setting for the DSP card, may have to be changed. Try using COM1, COM2, or COM3. * Testing has revealed that when the DSP modem is used in a PC that has a local bus graphics accelerator card that uses an ATI processor, system hangs sometimes occur. This is due to the ATI processor's interaction with system memory refresh. ATI has been made aware of this condition. When this condition occurs, your only recourse is to turn your system power OFF and ON (or press the system RESET switch if you have one) to restart your system. * Testing has revealed that when the DSP modem is used in a PC that has a fixed disk connected to a SCSI adapter using the base address 0330h to 0335h, the system is unable to recognize the hard disk during boot up. * Testing has revealed that several PC utilities have not been able to report the DSP modem in the system. These are DOS utilities that are not checking hardware installed for Windows. We have informed most of these companies. 3. MODEM INFORMATION * When setting up a communications application to work with the DSP modem, you should set the modem type as one of the following: IBM modem, or ACE 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.) * The semicolon dial modifier (for the AT D command) must be the last character in the command string. Any commands between the semicolon and the Carriage Return will be ignored. Example: ATDT1234567,,,,33333,,,,;H (The H will be ignored). To accomplish the same function as the example, do the following: ATDT1234567,,,,33333,,,,; ATH * Modem compatibility testing has revealed the need for the following helpful tips for using your DSP modem: Note: References below to Mwave Modem refer to the programs in your DSP Modem group that should be running in Windows. You should see either a visual image of a modem on your screen, or a minimized version of the same. The large version of the modem will have several "lights" with names like "FS", "AA", "RD", "TD", and "CD". The minimized version of the modem will not have the names, but will show the "lights". A) Scenario: Mwave Modem 9600 (V.32) fails to connect at 2400 bps or lower speed modem. Tip: It is difficult for V.32 (9600 bps) modems to handshake and get connections with a few older 2400 bps or slower modems. If the Mwave Modem 9600 is not connecting with a 2400 bps modem, try setting the DSP modem to negotiate at 2400 bps or below. There are several ways to do this: Option 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. Option 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. Option 3. Load the Mwave Modem 2400 instead of the Mwave Modem 9600. The COM Port can be set to any rate at or above the connect rate. If the connection still fails, try option 3 with option 1; if it still fails, then try option 3 in combination with option 2. B) Scenario: DSP modem does not connect to a 300 bps or below modem. Tips: 1. Set the DSP 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) 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 features for 300 bps or below since most modems do not support MNP features at these rates. You can disable MNP with the AT\N0 command. C) Scenario: Mwave Modem 2400 calls a bulletin board line that supports 9600 bps or above and they fail to complete the connection. Tip: 1. Many bulletin boards that charge extra for 9600 bps or above service will only connect at the supported rate. This prevents accidental charging for the high speed line when a connection is negotiated to a lower speed. For services with this restriction (for example, Prodigy and CompuServe), the DSP modem must be used to call the 9600 bps bulletin board. There should be no such difficulty when calling a 2400 bps bulletin board with the Mwave Modem 9600. D) Scenario: Using DOS communication application to drive the DSP modem, and the receive data appears to get dropped when being output to the screen. Tip: 1. 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: Use this for DOS communications applications only. E) Scenario: My modem locks up when I use it with multiple Windows applications. Tip: You should make sure to install your DSP Modem as the first available COM port. If your system does not currently have a COM1 port, you should install the DSP Modem as COM1. If you already have a COM1 port only installed in your system, you should install the DSP Modem as COM2. If you have both COM1 and COM2 installed in your system, you should install the DSP Modem as COM3, etc. * You may need a 486 PC with 8MB of RAM (or more) when running a MIDI application with 9600 or 14,400 bps modem. 4. FAX INFORMATION * Now Included is V.17 for fax transmission at 14.4kbps. * PLEASE NOTE that Class 2 fax emulation is not included with this release. * When viewing faxes using the QuickLink fax viewer, there can be lines of "noise" in viewed faxes. This is observed when scrolling the faxes in the fax viewer. The line noise is annoying, but is not saved to the fax file at all. * You can not remove a scheduled fax from the fax schedule list in QuickLink if the Call Manager is in the process of sending the scheduled fax. Close down the Call Manager and then go to the fax schedule to delete the fax. 5. TELEPHONE ANSWERING MACHINE (TAM) INFORMATION * You should try out your microphone to find the optimum speaking distance to avoid clipping. The way to do this is to go into QuickLink MessageCenter(tm) - QLMC - open the Messages dialog, and record a greeting using the microphone. If, when playing this greeting, it is too loud or very choppy-sounding you should move away from the microphone and re-record it. For a wide range of microphones, twelve inches or so seems to be a good distance between the person speaking and the microphone. Experience reveals that with DSP modem TAM, the following microphone characteristics produce the best results: - Uni-directional (works best for general purpose usage like recording greetings) - Impedance 600 ohms - Mono Dynamic - Cardiod Using a desk-top microphone stand, placed approximately 12-18 inches from the person speaking, has also proven to be beneficial. While this is not an endorsement of any kind, we have found the Radio Shack Model 33-1073 microphone to be compatible with the DSP modem TAM function. Using this microphone requires using a 1/4-inch stereo female to 1/8-inch stereo male adapter between the microphone and the DSP modem adapter MIC connector. * If the caller hangs up during the Greeting, QLMC will save a blank message in the Log. 6. AUDIO SYSTEM INFORMATION * 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. Here are some tips which may improve recording results: - Erase unnecessary files from the hard disk. - Use a defragmentation program to create a large contiguous free region on your hard disk. - If using the Mwave Recorder, increasing the amount of memory available to Windows may improve recording. To do this, run the Control Panel in the Main program group. Double click the "Drivers" icon or select "Drivers" from the "Settings" menu. Select the "MCI Sound" entry in the list box. Press the "Setup" button. You will be presented with a scroll bar. Moving the slider to the right will increase the amount of memory that Windows makes available for wave recording. The default setting allocates four seconds of memory. Increasing this amount may help. - 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. Some computers, particularly those with 16 MHz 386 processors, have been observed to hang or produce poor quality recordings when using higher sample rates and resolutions. In particular, attempting to record 44 KHz 16 bit stereo may prove to be difficult on all but the fastest computers. * 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. * When the MIDI Synthesizer attempts to play notes above the range of available samples, a default tone will play at the correct pitch but with a simple bell-like timbre. This scenario can be avoided by transposing the part being played down one or more octaves. This transposition can be performed by standard sequencing software. Alternately, this transposition can be performed by the MIDI Mapper in the Windows Control Panel. By associating the "-1 octave" Key Map with the instrument in the Patch Map, that instrument's notes will be lowered by an octave and the default timbre will be avoided. * Sounds can be associated with various Windows events via the Windows Control Panel. If other Mwave components such as the Mwave Modem, FAX, or Telephone Answering Machine are in use when such an event occurs, it is possible that no sound will be produced. Furthermore, Windows may display a pop-up window indicating that the sound driver is currently in use and not available. Please ignore any such warnings. To avoid this warning, you can turn off sound in the sound control panel of the Windows control panel. 7. CD-ROM The CD-ROM drives that can attach to the DSP modem are Panasonic models 562 and 563. These CD-ROM drives will cable easily to the card. You should use the MSCDEX.EXE driver to enable CD-ROM functions. The MSCDEX.EXE driver is available from Microsoft. This driver also ships with most CD-ROM drives. The audio cables for these CD-ROMs come in two varieties. The first cable, which can be used with the DSP modem, has a connector that has three pins in it. The second cable, which cannot be used with the DSP modem, has four pins and cannot be used with the DSP modem. If you get this cable with your CD-ROM, you should contact the place from which you purchased the CD-ROM in order to get a cable that will work properly. The flat ribbon cable with a 2x20 connector MUST be installed so that the pin 1 mark, usually a dot or arrow, coincides with the dot on the card. Refer to the User's Guide for details. 8. DOS Games Audio Enhancement Allows most DOS games designed to run on a Sound Blaster or compatible sound card to run on the IBM DSP card. 8.1 General Information The IBM DSP provides audio for most DOS and Windows games. A small number of games run in DOS protected mode and do not work with the IBM DSP. To use the IBM DSP, the DOS game must run in a Windows DOS session. To start a DOS game from Windows, choose one of the following procedures: - From the Main group in Windows' Program Manager, double click on the MS-DOS Prompt icon, and then follow the instructions in the game's user's manual for starting the game. - From the game's directory, enter "WIN" followed by the startup command for the game. This will start Windows, go to a DOS session under Windows, and start the game. For example: WIN XWING When you finish the game, you can exit Windows by typing Alt+F4 and then Enter. The IBM DSP Mwave drivers use the Sound Blaster/Adlib interface for DOS Games Audio. The IBM DSP Mwave drivers are automatically loaded the first time the game tries to access the Sound Blaster/Adlib interface. Most DOS games automatically detect the presence of this interface, but for those games that ask what kind of sound board is installed, choose Sound Blaster, Sound Blaster Pro, Sound Blaster 16, or Adlib. Some games perform differently for each interface, so if you are not getting the performance that you expect, try reinstalling the game and select a different interface. 8.1.1 VOLUME CONTROL To adjust the volume while you are playing a game: Increase volume: Ctrl+Alt+U Decrease volume: Ctrl+Alt+D 8.1.2 TELEGAMING With this release, DOS games can be run at the same time as the IBM DSP 2400 bps modem. Usually it is easier to load the modem before you start to play the game. See your IBM DSP User's Guide for complete instructions on using the 2400 bps modem. 8.2.TROUBLESHOOTING PROBLEMS WITH DOS GAMES The manufacturers of DOS games use a wide variety of techniques to give their games unique functions and performance. This diversity can cause problems for the user. This section attempts to give you help and guidance for some of the most commonly encountered problems such as insufficient memory. But, the best reference is the user's manual for the specific game that is a problem. The game manufacturers usually provide extensive help and suggestions to overcome problems unique to their game. 8.2.1 UNSUPPORTED MODES Your IBM DSP hardware does not currently support digitized sound in either "Direct Mode" or "ADPCM Mode" . For the few games which use these modes (some examples are listed below in the section entitled "Hints to Help with Specific Games"), we suggest that you try the following: For games which use direct mode, try setting the game up to run on an Adlib card rather than on a Sound Blaster. This will probably disable all digitized sounds, but will allow the game to run with synthesized music. If you find that your game suddenly runs VERY slowly for a while, selecting Adlib may improve performance. For games which use ADPCM mode, you need not make any changes. However, you will not hear any digitized sounds which use ADPCM. Otherwise, the game should continue to run normally. A few games (most of them from Microprose) attempt to produce speech using FM synthesis. This feature is not supported by Mwave. Speech produced this way may sound garbled. 8.2.2.SETTING THE DOS ENVIRONMENT VARIABLE A few games require that an environment variable be defined which will point the game to the location of the sound hardware. If you have such a game, you must put the following line in the AUTOEXEC.BAT file: SET BLASTER=A220 I7 D1 T3 Please refer to your DOS manual for instructions on editing files. When you have finished, reboot your machine. In this line, "A220" tells your game that sound hardware can be found at port address 220. Similarly, "I7" and "D1" tell the game to use interrupt level 7 and DMA channel 1. These are the default settings that were used when you installed your IBM DSP software. If you have changed these settings, the "SET BLASTER= . . ." line must be changed accordingly. Please refer to your IBM DSP User's Guide for information on changing these settings, or see the section entitled "Game Audio Port Address, Interrupt Line, and DMA Channel" below. 8.2.3.GAME AUDIO PORT ADDRESS, INTERRUPT LINE, AND DMA CHANNEL Most games automatically determine the port address, interrupt line, and DMA channel settings for the DOS games audio hardware. But if the game asks for this information, specify a port address of 220, interrupt line (IRQ) of 7, and a DMA channel of 1. These are default settings in the IBM DSP Mwave driver. In the unlikely event that you need to change these settings, you may edit them using the setup panel for the Mwave Games driver. To view this panel, open the Control Panel application in the Main group of Windows' Program Manager and then open the Drivers control panel. Click on Mwave Games and then click on Setup. The setup panel appears, allowing you to change these settings. 8.2.4.CONFLICTS WITH OTHER HARDWARE Generally speaking, DOS games will not run on a machine with two Sound Blaster-compatible sound cards installed. Nor will they run on IBM DSP if another card is present. If you already have such a card in your computer, it is recommended that you disable the "DOS Games Audio" function on your IBM DSP card. Please refer to your User's Guide to learn how this is done, or see the section entitled "Disabling DOS Games Audio" below. 8.2.5.DISABLING DOS GAMES AUDIO The setup panel for the Mwave Games driver contains an Enable Games control. Instructions for viewing the setup panel can be found in the section "Game Audio Port Address, Interrupt Line, and DMA Channel" above. An X in the Enable Games box enables the IBM DSP's DOS Games Audio options, while an empty box indicates that this option has been disabled. One reason for disabling the IBM DSP DOS Games Audio option would be the presence of another sound adapter in your computer. If you want to use a different sound adapter just for games, and the IBM DSP for other applications, remove the X from the Enable Games box. 8.2.6.HINTS TO HELP WITH SPECIFIC GAMES 4-D Boxing - This game uses some ADPCM digitized sounds, which will not be heard on IBM DSP. Chessmaster 3000 - Be sure to run "SBLASTER.COM" before starting the game. It must be run in the DOS session in which Chessmaster will be run. Comanche - Maximum Overkill - Comanche will not run under Windows. Commander Keen IV - This game will take about a minute to initialize itself before you can begin to play. The words "Initializing . . . Please Wait" will flash while this is happening. Doom - Doom will not run (with sound) under Windows. F-15 Strike Eagle II - F-15 II will not run under Windows. F-15 Strike Eagle III - Unless you have a very fast computer, low resolution graphics must be used to get acceptable performance. See the game manual for more information. F117 - This game will not run on this version of Mwave DOS Games Audio. Falcon 3.0 - This game uses direct mode digitized sounds, which may cause the program to run very slowly during the introduction as two planes fly by, and when you crash. To avoid this, configure your game for "none" under "radio messages" and for "Adlib" under "music". Front Page Sports Football - This game will not run unless you install the patch disk, available from Sierra Customer Service (phone: 800-SIERRA5). Also, the game must be set to run on an Adlib card rather than a Sound Blaster. Kid's Zoo (and other games from Knowledge Adventure) - For best results, edit the PIF file for "Kid's Zoo" (ZOO.PIF) so that "High Graphics" is not selected from the "Display Options" in the "Advanced Options". Otherwise, the game might hang occasionally. Note that a "High Graphics" option also appears in the first screen of the PIF editor. Ignore this option, click on "Advanced . . ." , and edit the entry in the "Advanced Options" page only. Please look in your Windows User's Guide for help using the PIF Editor. Links386 - Links386 will not run with sound under Windows. Lemmings & Lemmings 2 - On some computers, Lemmings 2 will occasionally run either too fast or too slowly. Exit the game, start again, and it will usually run at the correct speed. The original Lemmings will not run under Windows. Lost Files of Sherlock Holmes - This game uses ADPCM digitized sounds, which will not be heard on IBM DSP. Also, the program which displays the Electronic Arts logo might hang. You can get around the logo screen by running the program "GAME.EXE" rather than "HOLMES.BAT". Manhole - This game uses direct mode digitized sounds, which will not be heard on Mwave. Music will play. Martian Memorandum (and other games from Access) - Under Windows, Martian Memorandum often hangs as it begins to run. If the program makes it to the first screen, it will run properly. Deleting the configuration file, MM.CFG, and restarting the game will sometimes help. Murder Makes Strange Deadfellows - This game will not run on this version of Mwave DOS Games Audio. Populous II - This game uses ADPCM digitized sounds, which will not be heard on IBM DSP. Also, the program which displays the introduction might hang. You can get around the logo screen by running the program "POP2 /SS". The Presidents (and other games from National Geographic) - This game will not run on this version of Mwave DOS Games Audio. Prince of Persia II - Occasionally the introduction will stop after the first few words. When this happens, you can usually continue play by pressing the Enter key. Rebel Assault - Start Rebel Assault by entering "REBEL2" at the DOS command prompt. If the game hangs, try removing EMM386 from your CONFIG.SYS, reboot, restart Windows, and run "REBEL2" again. Return to Zork - From the list of audio cards supported, choose "mostly Sound Blaster compatible". The audio in the opening scene might break up occasionally, depending upon the speed of your machine. The rest of the game runs fine. Starcon II - This game does not provide sound support when running under Windows. Syndicate - This game does not provide sound support when running under Windows. Undersea Adventure (and other games from Knowledge Adventure) - For best results, edit the PIF file for "Undersea Adventure" so that "High Graphics" is not selected from the "Display Options" in the "Advanced Options". Otherwise, the game might hang occasionally. Note that a "High Graphics" option also appears in the first screen of the PIF editor. Ignore this option, click on "Advanced . . .", and edit the entry in the "Advanced Options" page only. Please look in your Windows User's Guide for help using the PIF Editor. Where In xxx Is Carmen San Diego - Most of the games in the Carmen San Diego family will now run on Mwave. However, the version of "Where in the World is Carmen San Diego, Deluxe" which has a 1992 copyright will not run under Windows. Therefore it will not run on Mwave. Copyright 1993 versions will work on Mwave. 8.2.7.MAKING MORE MEMORY AVAILABLE TO GAMES Many DOS games require lots of DOS memory, and some even require you to start your PC from a "clean boot" disk. Check the game's user's manual for special instructions. Some games will give you a message, "not enough memory", when you attempt to start the game, but some will just lock up the computer, if you do not have enough memory. With DOS 5.0 or later, you should be able to free over 590 KBytes of memory in a DOS session of Windows, which should be sufficient for most DOS games. Here are some suggestions to get the maximum memory available: Use the DOS command: MEM /C to determine how much free memory is available. If you are using MS-DOS 6.0, run the MEMMAKER program that comes with DOS to automatically make changes to your CONFIG.SYS and AUTOEXEC.BAT files. If you are using MS-DOS 5.0, use EMM386 and HIMEM to load any necessary device drivers (such as CD-ROM) into high memory. Consult your DOS User's Guide for information. Create a "clean boot" disk, (using the directions below) and start your computer with this disk before starting Windows. Finally, the manufacturers of DOS games that require unusually large amounts of memory realize that they have a potential usability problem, and as a result they usually provide extensive help and suggestions in the game's user's manual. If you are not successful with the suggestions given here, the best reference is the user's manual for the specific game that is a problem. Refer to their directions for creating more free memory, usually in the technical supplement or troubleshooting section. 8.2.8.CREATING A CLEAN BOOT DISK 1. Put a blank disk in the A: drive and type the following at the DOS prompt: FORMAT A: /S 2. Create a CONFIG.SYS file something like: DEVICE=C:\DOS\HIMEM.SYS DEVICE=C:\DOS\EMM386.EXE NOEMS DOS=HIGH, UMB FILES=20 BUFFERS=15 STACKS=0,0 (This example assumes Windows and DOS are located on the C: drive.) If your game requires expanded memory, eliminate NOEMS in the second line of the above CONFIG.SYS sample and replace it with nnn RAM, where nnn is the amount of expanded memory required by the game (see the game's user's guide). To make the best use of high memory, any "DEVICE= . . ." statement that you add to the CONFIG.SYS sample should be changed to "DEVICEHIGH= . . ." . (Do not change the DEVICE=C:\DOS\HIMEM.SYS or DEVICE=C:\DOS\EMM386.EXE NOEMS statements.) 3. Create an AUTOEXEC.BAT file something like: @ECHO OFF PROMPT $p$g PATH=C:\WINDOWS;C:\DOS LOADHIGH C:\DOS\MOUSE.COM NOTE: Today, most games require a mouse, therefore we have included a statement to load your mouse driver into high memory (LOADHIGH C:\DOS\MOUSE.COM), but if your game does not use the mouse you may remove this statement. Do not include programs like SMARTDRV.EXE in your AUTOEXEC.BAT 4. Start the computer with this "clean boot" disk in the A: drive. 5. Start Windows 6. Double click on the MS-DOS Prompt icon in the Main group in Windows' Program Manager. 7. Start the game as directed in the game's user's manual. 8.2.9.IMPROVING PERFORMANCE OF DOS GAMES IN A WINDOWS SESSION A few DOS games run slower in a Windows DOS session than in native DOS. Check the user manual of your game for special instructions about improving performance. You might try configuring Windows to use the VGA display driver rather than a higher resolution or less efficient driver. Also, see if your game allows you to turn off "background music" and only play special effects. 9. PLANNED ENHANCEMENTS * Telephony Enhancement I (P/N 92G7505 - Now available) Includes enablers for Caller ID and Full Duplex Speaker Phone. With separately purchased vendor application, on can be informed of the caller's number prior to picking up the phone. Advanced applications can access the caller's name, files, and notes from prior conversations in preparation of the phone call. Full Duplex Speaker Phone allows voice data to be received and transmitted concurrently to allow for more natural conversation over a headset, speakers, and/or microphone. 10.CORRECTIONS TO THE 'IBM V.32bis DSP Data/Fax Modem' USER'S GUIDE Due to rapid changes and additions to the DSP Modem functions this product is now known as the IBM DSP Modem and Audio Adapter. This description applies to the user's guide as well. p. 2 The list of option package contents should also include: - DSP Modem Install Diskette - Diskette 3 p. 15 Step 6 of Using the Mwave Verification Program should state that the diagnostics program will prompt you to remove all cables, excluding phone line cables, for both the basic and advanced diagnostics procedures. p. 25 Step 5 of Installing the DSP Modem Support Drivers directs the user to proceed to step 12 on page 29 if "Complete Installation of IBM_DSP System" is selected. This is incorrect. The user should proceed with step 6. Step 6 also directs the user to continue with step 12. If a Selective Installation is being performed, however, the user should instead continue with step 11 on page 28. p. 28 If you are performing a Complete Installation, step 11 is skipped. p. 38 The section Starting the Modem on this page states that the modem object will initially be minimized (i.e. displayed as an icon). Actually, the modem object may start off as a full-sized window. p. 47 The Game choice that is mentioned in the Options section should be called the Audio/Image Synch choice. p. 49 The Record Format dialog box shown on this page may be slightly different from the actual dialog box in the Mwave Recorder program.
