      Alps AMOUSE Mouse and GlidePoint Driver for DOS

                  Guide to Option Settings


The AMOUSE driver is preconfigured with default settings for
both mice and GlidePoint that many people find suitable for
general use. However, it also supports a wide range of
hardware and software settings to handle almost any

You can override the default settings by adding option
switches to the AMOUSE 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 the better place for your
long-term preferences. This distinction reflects the fact
that AMOUSE 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 AMOUSE commands.

During its initial load, AMOUSE 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.


From the DOS prompt, type AMOUSE 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.


This section provides full details on all AMOUSE command
line switches and MOUSE.INI statements, including background
information and explanatory notes.

You can type AMOUSE /? from the DOS prompt at any time to
display a summary of the command line options. (This assumes
AMOUSE.COM is in the current directory or on your DOS PATH.)


International versions of AMOUSE let you select the language
used for driver messages. The available languages will be
drawn from the following list:

     Switch    MOUSE.INI
     ------    ------------------
      /L       Language = English
      /LD      Language = German
      /LDN     Language = Danish
      /LE      Language = Spanish
      /LF      Language = French
      /LI      Language = Italian
      /LJ      Language = Japanese
      /LK      Language = Hangeul
      /LN      Language = Norweigan
      /LNL     Language = Dutch
      /LP      Language = Portuguese
      /LS      Language = Swedish
      /LSF     Language = Finnish

Consult the AMOUSE /? help screen for the languages
supported by your driver version. Except in Far East
(Japanese or Hangeul) versions, English is the default.

Mouse Type

The first time you run a newly installed AMOUSE driver, it
automatically searches for supported mouse types on various
hardware ports. This search may take up to several seconds.
If it succeeds (as it usually does), the result is written
to MOUSE.INI so future loads can avoid the delay. No option
switches are needed in this case.

   NOTE: As used in this document, the term "mouse"
   refers to any compatible pointing device, including
   Alps mice, trackballs and stick pointers; Alps
   GlidePoint; as well as conventional two and three
   button mice from other companies.

Certain mouse types or nonstandard ports cannot be detected;
in these cases, you must supply more information to the
driver. Use the material 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.

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

Serial mice can be further classified by their low-level
data formats, named here for the originating vendors. This
option is mandatory for Mouse Systems compatible mice, which
unlike other types cannot be detected through software. (For
the same reason, Mouse Systems compatibles also require an
explicit port number unless used on the default COM1.)

     Switch    MOUSE.INI                       Comments
     ------    --------------------------      -----------
      /MI      CompatibleWith = Microsoft      2-button
      /LOM     CompatibleWith = LogitechM      "M+" series
      /LOC     CompatibleWith = LogitechC      "C" series
      /MO      CompatibleWith = MouseSystems   3-button

Adding a "!" character to any of the serial format options
(e.g., "AMOUSE /MI!" or "CompatibleWith = Microsoft!") tells
the driver to force the specified installation, even if the
mouse does not respond to detection attempts. If you specify
the Mouse Systems format (always undetectable), the "!" is

The remaining cases which require more information involve
nonstandard ports, especially custom serial ports. If your
system is in this category, you probably already know about
it, having acquired such specialized hardware for your own
reasons. Otherwise, installation failures are more likely
due to physical problems such as loose connections or
hardware malfunctions.

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 device like the external Alps GlidePoint or the
Alps Adjustable Mouse, additional options control how the
third button behaves.

     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 (or Top). 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 devices, 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.

Third Button Options

The AMOUSE driver provides several options for the "extra"
button on three-button devices, such as the middle button of
a three-button mouse. (In the Alps Portable GlidePoint, the
extra button is the top button, while on the Alps Keyboard
and Desktop GlidePoint it is the right-hand side button.)
More generally, it is the button remaining after the primary
and secondary assignments described above.

By default, the driver is set to make the third button act
exactly like the Primary button. If you prefer, you can have
it act as an independent Auxiliary button in programs that
support three-button devices. But few programs recognize
more than two buttons, so the final alternative provides a
useful Drag Lock feature.

     Switch    MOUSE.INI               Third Button Action
     ------    ---------------------   -------------------
      /K       DragLock = Off          Same as Primary
               EnableAuxiliary = Off

      /KA      DragLock = Off          Auxiliary Button
               EnableAuxiliary = On

      /KD      DragLock = On           Drag Lock

   NOTE: As shown here, the MOUSE.INI EnableAuxiliary
   setting applies only when DragLock = Off. These third-
   button settings appear in the [mouse] section.

With Drag Lock enabled on the third button, pressing and
releasing this button is the same as holding the primary
button down. The primary button stays down (as seen by
applications) until the next time you press and release any
button, or tap the GlidePoint surface.

You can think of the Drag Lock option as converting the
third button into a latched version of the primary button
(click to hold, move as desired, click again to release).


This option lets you rotate the apparent direction of mouse
motion, as viewed on the display. Such action is required
when a clip-on trackball is mounted on the left side of a
laptop keyboard. (Otherwise the screen pointer appears to
move backwards and upside down.) Less dramatic adjustments
can also be helpful to GlidePoint or mouse users, by
compensating for different hand positions.

     Switch    MOUSE.INI
     ------    -------------------------
      /Or      RotationAngle = r (0-359)

In the case of the left-mounted trackball, the /O180 switch
will provide 180 degrees of rotation, compensating for the
mounting position. Check the result, making additional fine
adjustments as necessary, until you are satisfied with how
the screen pointer tracks your physical motion. After
finding your preferred rotation angle, edit MOUSE.INI to
store this setting for future use.

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 AMOUSE 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. AMOUSE 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. AMOUSE includes full APM support as a standard
   feature, requiring no option settings or switches.

 * Mouse Power Management is an AMOUSE 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 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 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

 * 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

     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
"AMOUSE /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.
