Practical Peripherals and Serial Mouse Configuration

 Last reviewed: September 16, 1996
Article ID: Q66536
The information in this article applies to:
  • Microsoft Mouse Driver for MS-DOS, versions 6.x, 7.x, and 8.x
  • Microsoft Serial Mouse, version 1.0

SYMPTOMS

If the Microsoft Serial Mouse is connected to COM 1, then a Practical Peripherals 2400 baud rate modem cannot be configured as COM 2. This modem/mouse combination may work for a while, but eventually it fails.

CAUSE

This problem is caused by an I/O address conflict between the mouse and the modem.

RESOLUTION

Practical Peripherals technical support confirmed this to be a problem. They recommend that the modem be configured as COM 3 or COM 4. The mouse should then remain on COM 1 to separate the I/O addresses as much as possible.

The Practical Peripherals product included here is manufactured by a vendor independent of Microsoft; we make no warranty, implied or otherwise, regarding this product's performance or reliability.
