# ufintek.4

`ufintek` — Fintek F81232 USB 串口 UART 驱动

## 名称

`ufintek`

## 概要

`device usb device ucom device ufintek`

在 rc.conf(5) 中：`kld_list="ufintek"`

在 sysctl.conf(5) 中：`hw.usb.ufintek.debug=1`

## 描述

`ufintek` 驱动为 FINTEK 的 F81232 串口适配器提供支持。若检测到相应硬件，该驱动会由 [devmatch(8)](/man/man8/devmatch.8.md) 自动加载。若要手动加载该驱动，请将其加入 [rc.conf(5)](/man/man5/rc.conf.5.md) 中的 `kld_list`，或在运行时使用 [kldload(8)](/man/man8/kldload.8.md)。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)。

通过此接口可使用 cu(1) 或 tip(1) 等应用程序进行呼出。

## 硬件

`ufintek` 驱动支持以下 USB 串口 UART 控制器：

* FT82332

## SYSCTL 变量

以下设置可在 [loader(8)](/man/man8/loader.8.md) 提示符下输入，在 loader.conf(5)、[sysctl.conf(5)](/man/man5/sysctl.conf.5.md) 中设置，或在运行时通过 [sysctl(8)](/man/man8/sysctl.8.md) 更改：

**`hw.usb.uftdi.debug`** 启用调试消息，默认 `0` `1`

## 文件

**`/dev/ttyU*`** 用于呼入端口 **`/dev/ttyU*.init`** **`/dev/ttyU*.lock`** 对应的呼入初始状态和锁定状态设备 **`/dev/cuaU*`** 用于呼出端口 **`/dev/cuaU*.init`** **`/dev/cuaU*.lock`** 对应的呼出初始状态和锁定状态设备

## 参见

cu(1), [tty(4)](/man/man4/tty.4.md), [ucom(4)](/man/man4/ucom.4.md), [usb(4)](/man/man4/usb.4.md)

## 历史

`ufintek` 驱动首次出现于 FreeBSD 16.0。

## 缺陷

此驱动仅支持 9600 波特率。

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/ufintek.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.
