Using the Logitech Mouse Driver for Windows 3.1:

INSTALLATION

Windows 3.1 includes both the DOS and Windows level drivers necessary
for all Logitech mice.  Most difficulties within Windows 3.1 arise from
the installation of the wrong drivers.  To make sure the correct drivers
are installed, please follow the steps below:

1.  Go the the Windows directory (usually C:\WINDOWS)
2.  Type SETUP, then press ENTER.
3.  Once at the HARDWARE SETUP screen, use the cursor keys to highlight
    the mouse selection.  Press ENTER.
4.  Select the Logitech selection.  Press ENTER.
5.  Press ENTER again to ACCEPT CONFIGURATION.
6.  Press the ESCape key to install a new driver.
7.  Insert the requested Windows diskette (usually #2)
8.  Make sure the path matches the drive in which the diskette was 
    inserted (A:\ or B:\).  Press ENTER.

You have now installed the Mouse drivers for Windows.  This installation 
procedure simultaneously copies a file called LMOUSE.COM to the 
Windows directory.  This file is a Windows 3.1 compatible DOS mouse driver.
To update your current DOS mouse driver to version 6.02, please follow
the steps below:

1.  Go to the Windows directory.
2.  Type COPY LMOUSE.COM C:\MOUSE\MOUSE.COM.  Press ENTER
3.  Reboot.

(where C:\MOUSE\ is the drive and directory which contains the older mouse
driver)
The commands listed above rename the necessary file to MOUSE.COM and copy
it into the mouse directory, where it will replace the older mouse driver. 

NOTE: Please note that versions of Logimenu and Click older than 6.0 will not 
      function with this newer MOUSE.COM.  If you need Logimenu, Click, AND 
      the newest mouse driver, you will need to contact Customer Service at
      (510) 795-8100 for the full MouseWare upgrade.



SUPPORT WITHIN WINDOWS

Full mouse features, such as mouse trails and a mouse cursor in a windowed 
DOS application, are currently supported with standard Windows 3.1 VGA, EGA 
and CGA drivers.  These features may not work properly if Windows is 
configured to use a video manufacturer specific driver or if Windows is 
set up in a non-standard configuration.

-- Mouse Trails

One of the options available within the mouse control panel is a "Mouse 
Trail".  This feature is used primarily for those who use Windows
on a notebook or laptop computer using an LCD or Plasma video display. 
The mouse trail option becomes unavailable if Windows is set up to use any
high resolution video display driver.  This option sometimes becomes 
unavailable when using a manufacturer's video driver rather than the
standard Windows' driver.

-- Mouse Cursor in a DOS Window

Video card manufacturer supplied drivers can sometimes cause the loss of 
the mouse cursor or an erratic mouse cursor when using the mouse in a 
windowed DOS applications.  

If the mouse fails to function properly in a windowed DOS application, 
make sure you are using the latest Windows and DOS mouse drivers 
(included with Windows 3.1 or higher). Try setting up Windows 3.1 to work 
with the standard VGA, EGA or CGA display driver included with Windows 3.1. 
Make sure the following line appears under the [NonWindowsApp] section in 
the SYSTEM.INI:

MouseInDosBox=1

Any time the mouse is having difficulties within Windows 3.1, check the 
following:

1] Make sure the mouse is working properly with mouse-based DOS applications.  
If not, check for a possible hardware conflict between the mouse driver and 
some other device software within the system.  Another possibility would 
be a software conflict between the mouse driver and some RAM resident 
software within the system.  (Order document number 1000 from Logitech 
FaxBack for more information on troubleshooting a hardware/software 
conflict.)

2] Make sure you are using mouse driver 6.02 (LMOUSE.COM included with 
Windows 3.1) or above.  (Follow the procedures listed at the beginning
of this document.)

3] Make sure you are using the latest Logitech Windows mouse driver included
with Windows 3.1. These drivers are LMOUSE.DRV and LVMD.386.  These files 
should have a 1992 date. If not, see the above procedure for installing the 
latest Windows 3.1 Logitech mouse drivers.

4] Does the mouse work in Standard mode? If the mouse works in Standard mode  
but not in Enhanced, there could be some sort of software conflict between 
the mouse driver and another RAM resident program(s) in memory. Try booting 
the system with a plain DOS boot disk (see below for creating DOS boot disk) 
which doesn't load any RAM resident software, then try again. Also, make sure the following lines appear in the 
[386Enh] section of the SYSTEM.INI file:

mouse=lvmd.386
LOCAL=PC$MOUSE

Creating a DOS boot disk:

A) Format a disk in drive A: using FORMAT A: /S
B) Include the following system files on the DOS boot disk:

AUTOEXEC.BAT

PATH=C:\;C:\DOS;C:\WINDOWS
PROMPT $P$G
SET TEMP=C:\WINDOWS\TEMP {make sure that the TEMP directory exist)

CONFIG.SYS

FILES=40
BUFFERS=20
DEVICE=C:\WINDOWS\HIMEM.SYS
SHELL=C:\DOS\COMMAND.COM C:\DOS /P /E:256

5] Did the mouse work with Windows 3.0? If the mouse functioned with 
Windows 3.0 but is not working with Windows 3.1, select the standard VGA
video display driver (version 3.0) by running Windows 3.1 SETUP.  This 
will further isolate the problem.

Also, if you are using a Logitech Cordless MouseMan, try loading the DOS 
mouse driver with the parameter 1200 (by issuing the command MOUSE 1200 if 
using MOUSE.COM, or including DEVICE=C:\MOUSE\MOUSE.SYS /1200 in the CONFIG.
SYS file).  Then add the following line in the [LogiMouse] section in the 
SYSTEM.INI:

baudrate=1200

6] If you are using a Serial mouse, select the 386 Enhanced Icon in the  
Control Panel and change the device contention to "Never Warn" on the COM
port to which the mouse is connected.

7] In the Control Panel there is an icon for Ports.  There are four 
selections.  Select one port at a time, click on Settings, click on Advanced, 
then correctly select the I/O address and hardware interrupt corresponding 
to the COM port according to the table below: 

	COM Port        I/O Adress      Hardware Interrupt

	 COM 1             03F8                IRQ4
	 COM 2             02F8                IRQ3
	 COM 3             03E8                IRQ4
	 COM 4             02E8                IRQ3

COMMONLY ASKED QUESTIONS

Which runs faster in a DOS window -- Graphics mode or Text mode applications?

When using a mouse with a windowed DOS application, the application will 
run faster if set up to run in text mode rather than in graphics mode.  If 
speed is a consideration, configure the application to run in text mode if 
possible.  Check the PIF file for this application using the PIF editor to
determine whether it is being run in graphics or text mode.


When I start Windows, I see a mouse cursor on the screen but it won't
move.  What's wrong?

Many things could cause this symptom.  The most likely cause under Windows
3.1 is that the serial port is set up in a non-standard configuration.  On
a single serial port system, the port must be set up as COM 1.  On a 
multi serial port system, the first two COM ports should be set up as
COM 1 and COM 2.

This symptom can also be caused by the use of a Windows 3.0 video display
driver or an incorrect video display driver.
