README for DOS Mouse Driver ============================= This file contains supplemental information for the DOS Mouse Driver. Manual Installation =================== Using the INSTALL program is the fastest and easiest way to set up the driver software. However, you can also perform a manual installation through the following procedure: 1. Copy the contents of the Install disk to a single directory on your hard disk, as in this example: md c:\imouse copy a:*.* c:\imouse 2. Examine your CONFIG.SYS and AUTOEXEC.BAT files for possible conficts involving other pointing device drivers. These include commands that load the driver, or that set the MOUSE environment variable. Either remove such lines, or edit them to reflect your new installation, as outlined below. 3. To load the DOS mouse driver automatically through AUTOEXEC.BAT, use the following command syntax: set mouse=c:\imouse c:\imouse\imouse Substitute the actual drive and directory where your driver files reside. You may also wish to add this directory to your PATH statement. The optional SET MOUSE command specifies which directory the driver should search for its MOUSE.INI settings file. This example uses the same directory as the driver, duplicating its normal behavior. However, you can use this feature to maintain different MOUSE.INI files in separate locations. These changes will not take effect until you reboot your computer. Uninstalling the Driver ======================= To uninstall the driver, remove or remark out (REM) the following lines from AUTOEXEC.BAT: set mouse=c:\imouse c:\imouse\imouse You can also restore the file contents from the AUTOEXEC.BAK, a backup copy created by INSTALL. If you keep the IMOUSE directory and its contents intact, you can easily restore the installation later, without needing the original diskette. The next topic explains how. Restoring Your Installation =========================== During a first-time installation, the INSTALL program places a copy of itself in the same directory as the driver files. If you temporarily change drivers to use another pointing device, you can then use this copy of INSTALL to restore your installation without going back to the original driver diskette. All previous MOUSE.INI settings will also be preserved. This procedure works as long as you do not delete any of the installed driver files. To restore your installation: 1. Run the copy of INSTALL program found in your driver directory. For example, with the standard installation, use the following command: c:\imouse\install (You could also change to that location and simply type INSTALL.) 2. When INSTALL prompts you for a driver directory, be sure to specify the existing driver directory (containing INSTALL and the other files). In this case, no files will be copied. Instead, INSTALL will simply update AUTOEXEC.BAT to use your existing driver. CONFIGURING THE IMOUSE DRIVER ============================= The IMOUSE driver is preconfigured with default settings that many people may find suitable for general use. However, it also supports a wide range of hardware and software settings to handle almost any situation. You can override the default settings by adding option switches to the IMOUSE command line, or through statements in the MOUSE.INI configuration file. Command line options are more convenient for temporary adjustments or frequently changed items, while MOUSE.INI is a better place for your long-term preferences. This distinction reflects the fact that IMOUSE reads the MOUSE.INI settings only when you first load the driver into memory. Therefore, any changes to MOUSE.INI will not take effect until you either reboot the system or remove the driver from memory and reload it. Conversely, most of the resident driver settings can be changed simply by issuing new IMOUSE commands. During its initial load, IMOUSE normally looks for MOUSE.INI in the same directory where the driver resides. To specify a different location, set the MOUSE environment variable to the desired drive and path (e.g., SET MOUSE=C:\BIN) before loading the driver. This technique lets you keep multiple copies of MOUSE.INI for different purposes, without wasting disk space on identical copies of the driver. TESTING YOUR INSTALLATION ========================= From the DOS prompt, type IMOUSE TEST to run a simple diagnostic test built into the driver. If the driver loads successfully (or was already loaded before this command), the following line will appear after the copyright and status messages: -- Test mode active: press a key to quit -- While test mode is active, a mouse cursor appears on the current DOS screen, tracking the motion of your pointing device. The test mode cursor also responds to button presses by changing to the letter "P" (primary), "S" (secondary), "A" (auxiliary), or "*" (multiple buttons). When you are finished with test mode, press a keyboard key to quit and return to the DOS prompt. REFERENCE: OPTION SETTINGS ========================== This section provides full details on all IMOUSE command line switches and MOUSE.INI statements, including background information and explanatory notes. You can type IMOUSE /? from the DOS prompt at any time to display a summary of the command line options. (This assumes IMOUSE.COM is in the current directory or on your DOS PATH.) Language -------- International versions of IMOUSE let you select one of the following languages for driver messages: Switch MOUSE.INI ------ ------------------ /L Language = English /LD Language = German /LE Language = Spanish /LF Language = French /LI Language = Italian /LNL Language = Dutch Mouse Type ---------- The MouseType setting and associated switches actually describe the computer port where your mouse is attached. Because these options address the same ports as the driver's automatic search, their most common use is simply to speed the loading process. Users with multiple pointing devices can also use this method to specify which device should be activated. The following list matches the search order used by the driver: Switch MOUSE.INI ------ ------------------- /Z MouseType = PS2 /C1 MouseType = Serial1 /C2 MouseType = Serial2 /C3 MouseType = Serial3 /C4 MouseType = Serial4 /I1 MouseType = InPort1 /I2 MouseType = InPort2 /B MouseType = Bus If the driver does not detect a mouse on the specified port, it continues from the beginning of the default search order. For example, consider a laptop system with an internal PS/2 device and an external serial mouse which is not always available. If you set MouseType=Serial1, the system will use the serial mouse when it is present and the built-in PS/2 device otherwise. Certain nonstandard ports may not be detected successfully; in these cases, you must supply more information to the driver. Use the information in this section to determine the appropriate command line options. When you find the right switch or switches (and verify that the mouse is working properly), place the equivalent settings in MOUSE.INI to indicate your configuration. Before turning to the most general case, we must note a lack of uniformity among the "standard" serial port designations. Ports COM1 and COM2 are assumed to use the same addresses and interrupts on all systems, but COM3 and COM4 are not: Port AT-Bus PS/2 (Microchannel) ---- ----------- ------------------- COM1 03F8h, IRQ4 03F8h, IRQ4 COM2 02F8h, IRQ3 02F8h, IRQ3 COM3 03E8h, IRQ4 3220h, IRQ3 COM4 02E8h, IRQ3 3228h, IRQ3 If the driver does not recognize your use of COM3 or COM4, it may be misinterpreting your system type. You can override the automatic determination by adding the suffix "A" or "P" to the serial port command line switch. For example, /C3P specifies COM3 with PS/2-compatible addressing, while /C4A specifies COM4 with AT-compatible addressing. If the override works, you can supply the equivalent base address and IRQ through MOUSE.INI, as described next. The most flexible way of specifying a serial port requires both a base port address (3 or 4 hexadecimal digits) and IRQ number, using the following syntax: Switch MOUSE.INI ------ ----------------------------- /BAx BaseAddress = x (hexadecimal) /IRQn IRQnumber = n (2-5, 7, 10-15) If you specify a base address, you must also include the IRQ number. (In this case, any /Cn switch or MouseType setting is ignored. However, you can still use the serial format switches or CompatibleWith setting). Be careful with these parameters, as incorrect values can disrupt other devices! When specified without a base address, the IRQ parameter is assumed to modify an otherwise standard port designator. This usage also applies to the InPort and Bus mouse types, provided that the hardware can be suitably configured. Button Mapping -------------- The following options let you swap or rearrange the available mouse buttons to suit your convenience. With a three-button mouse, you can also redefine the third button to provide a click lock function (described next). Switch MOUSE.INI ------ ------------------------- /KPnSm PrimaryButton = n (1-3) SecondaryButton = m (1-3) To describe the button actions seen by your applications, we use the terms Primary, Secondary and Auxiliary instead of Left, Right and Middle. This more precise usage emphasizes the fact that applications do not read the physical buttons. In other words, what they consider a "left click" comes from whichever button you designate as Primary. The mapping options refer to physical buttons by number: 3-button mouse: left = 1, middle = 2, right = 3. 2-button mouse: left = 1, . . . right = 3. With a 2-button mouse, the driver also accepts references to button 2 as the right button. But calling it button 3 has the advantage of compatibility with all mouse types. Turning to examples, one common use of button mapping reverses the primary and secondary buttons for left-handers, so they can perform most mouse operations with the index finger. This is accomplished through the command switch /KP3S1 or setting PrimaryButton = 3 and SecondaryButton = 1. With 3-button mice, note that you do not specify the auxiliary button directly. Instead, when you specify the primary and secondary buttons, the driver automatically assigns the auxiliary role to the remaining button. For example, /KP1S2 moves the secondary role to the middle button, so the right button becomes the auxiliary. Click Lock ---------- Because few applications recognize more than two buttons, the click lock option provides an alternate function for the auxiliary button on a 3-button mouse (normally the middle button, unless the buttons have been remapped.) This option has no effect on a 2-button mouse. Switch MOUSE.INI ------ --------------- /KC ClickLock = On /K ClickLock = Off With click lock enabled, pressing and releasing the auxiliary button is equivalent to pressing and holding the primary button. The primary button stays down (as seen by applications) until you the next time you press and release any button. In other words, click lock makes the auxiliary button act like a latched version of the primary button. It lets you use the mouse to drag objects without having to hold any buttons down. Orientation ----------- This option lets you rotate the apparent direction of mouse motion, as viewed on the display. Mouse users can simply experiment with different settings, or take a more analytical approach: Imagine a "north/south" line on your desk or mouse pad, in the direction that feels most natural for up-and-down screen motion. Estimate the rotation angle from this axis, proceeding clockwise to the centerline of the mouse. The angle must be expressed as a positive number. For example, 30 degrees counter-clockwise would be expressed as /O330 (i.e., 360 minus 30). This example setting might describe a right-handed user who prefers holding the mouse with a slight inward twist. Memory Regions -------------- To maximize the amount of conventional memory (below 640K) available to DOS applications, the IMOUSE driver attempts to move its resident portion to other regions, if available. These regions include expanded memory (EMS 3.0 or higher), the High Memory Area (64K beginning at 1MB), and Upper Memory Blocks (between 640K and 1MB). As long as your memory manager or other necessary system files are loaded before the driver, this relocation proceeds automatically. You don't have to use the MS-DOS LOADHIGH or DEVICEHIGH commands, or their third-party equivalents. In fact, the driver's built-in relocator often succeeds in cases where external loaders fail. It also has the ability to split the driver between multiple regions. The following options provide explicit control over the driver's memory usage, letting you enable or disable access to each of the supported memory types: Switch MOUSE.INI ------ ------------ /E Memory = EMS /E- Memory = NoEMS /HI Memory = HMA /HI- Memory = NoHMA /U Memory = UMB /U- Memory = NoUMB /LOW Memory = LowMem You can specify multiple memory settings (separated by commas) in a single MOUSE.INI statement. For example, the following syntax will prevent all relocation attempts: Memory = NoEMS, NoHMA, NoUMB In the example above, the simple statement "Memory = LowMem" or the /LOW switch would yield the same result. Power Management ---------------- In some cases, the power conserving features of laptop computers or energy-efficient desktop systems may interfere with normal mouse operation. IMOUSE uses two strategies to address this problem: * Advanced Power Management (APM) is an industry standard specification that allows hardware and software from different vendors to cooperate in various power saving modes. IMOUSE includes full APM support as a standard feature, requiring no option settings or switches. * Mouse Power Management is an IMOUSE option intended for older systems (primarily laptops) whose power saving modes are not APM-compatible. It allows the driver to detect and recover from power interruptions that may not fully restore the hardware state. This option is normally disabled, because few systems require it. Switch MOUSE.INI ------ ------------------------- /MPM MousePowerManagement = On /MPM- MousePowerManagement = Off If your mouse behaves erratically after returning from "sleep" mode, try the /MPM switch. If the problem goes away, you can then edit MOUSE.INI to change the default setting. Sensitivity ----------- Sensitivity settings define how much the on-screen pointer moves in response to physical motion of your mouse or compatible pointing device. As shown below, you can set different sensitivities for horizontal and vertical motion. This feature can be helpful in specific situations, such as navigating spreadsheets. However, a uniform setting for both dimensions (specified by the /S switch) usually feels more natural. Switch MOUSE.INI ------ --------------------------------- /Hn HorizontalSensitivity = n (5-100) /Vn VerticalSensitivity = n (5-100) /Sn - n/a - Each setting takes values from 5 to 100, in steps of 5. (Other numbers in this range are rounded to the nearest valid step.) The default values are 50 in each dimension. Smaller values make the pointer easier to control, while larger values let you cover more of the screen with less hand motion. Acceleration ------------ Acceleration profiles provide a dynamic adjustment of the current sensitivity settings. In other words, sensitivity is concerned only with how FAR you move the physical device, while acceleration also depends on how FAST you move it. The driver includes four built-in acceleration profiles, which you select by number (profile 2, the default, gives "Medium" acceleration): Switch MOUSE.INI Description ------ ----------------------------- ------------ /P1 ActiveAccelerationProfile = 1 Slow /P2 ActiveAccelerationProfile = 2 Medium /P3 ActiveAccelerationProfile = 3 Fast /P4 ActiveAccelerationProfile = 4 Unaccelerated The descriptive names also appear in MOUSE.INI, along with data tables that define each of the standard profiles. By editing the data, serious hackers can create their own custom profiles. (This is not a project for the novice!) Pointer Appearance ================== Forcing the Default Text Cursor ------------------------------- Enabling this option prevents applications from changing the standard inverse-block "software cursor" used as a mouse pointer in most text-based programs. It has no effect on graphics-based programs, or on those using the text-mode "hardware cursor" provided by the video adapter. Switch MOUSE.INI ------ ------------------------ /M ForceDefaultCursor = Off /M1 ForceDefaultCursor = On Some applications use different mouse pointer types to provide useful status information. Therefore, this option should be restricted to specific programs whose changes make the pointer too difficult to see. Display Delay for LCD Screens ----------------------------- This option addresses a common problem with passive-matrix liquid crystal displays (LCDs). Rapidly moving images, such as the mouse pointer, may seem to disappear because the display responds too slowly for each intermediate position to become visible. Switch MOUSE.INI ------ ----------------------------- /Nn CursorDisplayDelay = n (0-10) Increasing the delay between screen updates gives each image more time to register on the LCD display. On the other hand, large delay values tend to make the pointer feel sluggish and less precise in its response. The best strategy is to use the lowest delay setting that keeps the moving pointer from getting lost. Pointer Color Options (Graphics Only) ------------------------------------- Several color-related options affect the way the mouse pointer appears in most graphics-based applications. First, the PointerColor options are effective in all graphics video modes. Assuming the current program has not replaced the standard mouse pointer with its own design, these options produce the following results: * Normal (the default setting) gives a bright white arrow pointer with black outline. * Reverse gives a black arrow pointer with bright white outline. * Transparent gives a "see through" pointer that changes color depending on the material it passes over (an effect similar to the standard text-mode mouse pointer). Switch MOUSE.INI ------ --------------------- /PCN PointerColor = Normal /PCR PointerColor = Reverse /PCT PointerColor = Transparent Additional control is available in 16-color and 256-color graphics modes, provided that the pointer is actually being drawn by the mouse driver (not the underlying application). Referring to the normal arrow pointer and its outline as Foreground and Background, you can change the colors used for these elements through the following syntax: Switch MOUSE.INI ------ ------------------------------------------ /PFn Foreground = color (default: Bright White) /PBn Background = color (default: Black) n Color Name n Color Name --- ----------- --- -------------- 0 Black 8 Bright Black 1 Blue 9 Bright Blue 2 Green 10 Bright Green 3 Cyan 11 Bright Cyan 4 Red 12 Bright Red 5 Magenta 13 Bright Magenta 6 Yellow 14 Bright Yellow 7 White 15 Bright White If you use the command line switches without numeric arguments, they revert to the default values /PF15 /PB0. Pointer Growth Options ---------------------- This option group lets you enhance the mouse pointer visibility through various forms of static or dynamic growth. Switch MOUSE.INI ------ --------------------- /PSS PointerSize = Small /PSM PointerSize = Medium /PSL PointerSize = Large /PG Growth = On /PG- Growth = Off /PZ Zoomable = On /PZ- Zoomable = Off /PTn Threshold = n (1-100) /PDn Delay = n (1-100) The most important setting in this group is PointerSize, which selects a small (default), medium or large pointer. What you see on-screen will vary depending on the current application (its video and mouse handling strategies) and on the remaining settings: * Small (the default setting) entirely disables all pointer growth features, regardless of the other settings. * Medium changes the text-mode mouse pointer to a tall and wide cross shape. Depending on the Zoomable setting, the standard graphics-mode pointer will either grow by 50% or acquire a shadow highlight. * Large changes the text-mode mouse pointer to a hollow box shape, three times taller and wider than the small setting. Depending on the Zoomable setting, the standard graphics-mode pointer will either double in height and width or acquire a shadow highlight. The Growth setting controls whether the PointerSize effects described above are static or dynamic: * Growth = On applies the Medium or Large settings only while the pointer is moving. When motion stops, the Small pointer returns. * Growth = Off (the default) keeps the specified size constant, whether the pointer is moving or not. The Zoomable setting controls how the Medium and Large pointers actually appear in graphics-based applications. This setting has no effect in text mode. * Zoomable = On selects a "true growth" strategy, drawing the Medium and Large pointers as magnified versions of the Small pointer. This strategy provides the maximum possible emphasis for difficult viewing conditions. * Zoomable = Off (the default) substitutes a shadow effect for the Medium and Large pointers. This strategy provides less emphasis than zooming, while still making it easier to follow the moving pointer. Threshold and Delay values control the timing of PointerSize effects when growth is enabled. When growth is disabled (preventing the pointer from changing size), these settings are ignored. * Threshold specifies how fast the mouse can move (on a scale of 1 to 100) before pointer growth occurs. A low threshold triggers growth very easily, while higher values require more motion. The default value is 20. * Delay specifies how long pointer growth lasts (on a scale of 1 to 100) after mouse motion stops. Low values cause the pointer to shrink back quickly, while larger delays allow more "settle" time. Each unit equals roughly one tenth of a second. The default value is 3. Command line switches make it easy to experiment with various combinations of pointer settings. For example, try "IMOUSE /PSL /PG /PZ /PF4 /PB12" to give your graphics-based DOS programs a large, dynamic zooming red pointer with a bright yellow outline. When you find the combination you like best, translate the switches into MOUSE.INI settings, where you can store them to replace the built-in defaults.
