# uvisor(4)

USB support for the PalmOS based PDAs

## NAME

**uvisor** – USB support for the PalmOS based PDAs

## SYNOPSIS

**device uvisor** **device ucom**

## DESCRIPTION

The **uvisor** driver provides support for USB based PalmOS PDAs, like Handspring Visor, Palm Mxxx series, and Sony Clie.

The device is accessed through the [ucom(4)](/ucom/4.md) driver which makes it behave like a [tty(4)](/tty/4.md). The device has several ports for different purposes, each of them gets its own [ucom(4)](/ucom/4.md) device. The attach message describes the purpose of each port.

The usual Pilot tools can be used to access the attached device on the HotSync port.

## HISTORY

The **uvisor** driver was adopted from NetBSD 1.5 in August 2002. This manual page was adopted from NetBSD by Tom Rhodes ⟨trhodes@FreeBSD.org⟩ at that time.

## BUGS

The code to provide multiple [ucom(4)](/ucom/4.md) instances has not yet been ported from NetBSD. It is unclear whether this driver works in its current state.
