# uvisor.4

`uvisor` — 基于 PalmOS 的 PDA 的 USB 支持

## 名称

`uvisor`

## 概要

要将此驱动编译进内核，请将以下行加入你的内核配置文件：

> device usb device ucom device uvisor

或者，要在引导时以模块方式加载该驱动，请将以下行加入 loader.conf(5)：

```sh
uvisor_load="YES"
```

## 描述

`uvisor` 驱动为基于 USB 的 PalmOS PDA 提供支持，例如 Handspring Visor、Palm Mxxx 系列和 Sony Clie。

该设备通过 [ucom(4)](/man/man4/ucom.4.md) 驱动访问，使其行为类似 [tty(4)](/man/man4/tty.4.md)。该设备具有多个用于不同目的的端口，每个端口都有自己的 [ucom(4)](/man/man4/ucom.4.md) 设备。附加消息描述了每个端口的用途。

可使用常规的 Pilot 工具在 HotSync 端口上访问附加的设备。

* Aceeca Mez1000 RDA
* Handspring Treo
* Handspring Treo 600

## 历史

`uvisor` 驱动于 2002 年 8 月从 NetBSD 1.5 引入。本手册页当时由 Tom Rhodes <trhodes@FreeBSD.org> 从 NetBSD 引入。

## 缺陷

提供多个 [ucom(4)](/man/man4/ucom.4.md) 实例的代码尚未从 NetBSD 移植。此驱动在当前状态下是否能正常工作尚不明确。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://book.bsdcn.org/man/man4/uvisor.4.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
