OS/2 and IBM ScrollPoint Mouse

This article describes my installation of the IBM ScrollPoint Mouse under IBM OS/2 Warp. The scrolling mouse driver was written by IBM and may be downloaded from the OS/2 support site.

I have used this driver with the IBM ScrollPoint Mouse, the Logitech First Mouse plus, and the Microsoft Wheel Mouse.

If you are using OS/2 Warp Server for e-Business, you already have support for the ScrollPoint mouse. A newer driver appears to be available at the link below.

How to use the ScrollPoint mouse

This is the part of the readme file that explains what the driver does and how to use it. I have tried this driver with the IBM ScrollPoint mouse (stick-type) and with the Logitech First Mouse + (wheel-type).

3.0 Scrolling Mouse Operating Parameters

The ScrollPoint Mouse driver supports both stick-type (ie., IBM ScrollPoint) and wheel-type (ie., Logitech MouseMan+) scrolling mice. The physical attributes of the scroller device in your scrolling mouse determines the operational characteristics of the scrolling portion of the mouse. Other features, including button functions, are the same as on a non-scrolling mouse.

3.1 Stick-Type Scrolling Mouse

A stick-type mouse will allow the cursor to move vertically either line-by-line or page-by-page and horizontally either space-by-space or tab-by-tab, depending on the amount of time the stick is held at its maximum-deflected position for the chosen direction.

Typically, up or down stick-deflections of less than one second will cause the cursor to move vertically on a line-by-line basis. When the stick is held deflected up or down for more than one second, the cursor will change its vertical movement from a line-by-line to a page-by-page motion.

Similarly, left or right stick-deflections of less than one second will cause the cursor to move horizontally on a space-by-space basis. When the stick is held deflected left or right for more than one second, the cursor will change its horizontal movement from a space-by-space to a tab-by-tab motion.
