# pms(4)

PS/2 auxiliary port mouse driver

## NAME

**pms** – PS/2 auxiliary port mouse driver

## SYNOPSIS

**pms\* at pckbc?** **pms\* at gsckbc?** (hppa) **wsmouse\* at pms? mux 0**

## DESCRIPTION

The **pms** drivers provide an interface to PS/2 auxiliary port mice within the [wscons(4)](/wscons/4.md) framework. Parent device in terms of the autoconfiguration framework can be either [gsckbc(4)](/gsckbc/4.md), the PS/2 input port controller found on hppa machines, or [pckbc(4)](/pckbc/4.md), the standard PC keyboard controller found on most other machines. “pms” is a generic driver which supports mice using common variants of the PS/2 protocol, including wheel mice of the “IntelliMouse” breed. Wheel movements are mapped to a third (z-) axis. Mouse related data are accessed by [wsmouse(4)](/wsmouse/4.md) devices.
