# uhso.4

`uhso` — 支持 Option N.V. 的若干 HSxPA 设备

## 名称

`uhso`

## 概要

`通过在 loader.conf(5) 中加入以下行，可在引导时加载此模块：`

```sh
uhso_load="YES"
```

## 描述

`uhso` 驱动为 Option N.V. 基于其分组接口的若干 HSxPA 设备提供支持。每个设备都有一组串口和一个原始 IP 分组接口。设备的串口通过 [ucom(4)](/man/man4/ucom.4.md) 驱动访问，使其行为类似 [tty(4)](/man/man4/tty.4.md) 设备。分组接口以网络接口形式呈现。

在分组接口上建立连接是通过在任一可用串口上使用专有 AT 命令“`AT_OWANCALL`”和“`AT_OWANDATA`”来实现的。

必须使用从这些调用获取的数据手动配置网络接口。

每个设备通常至少有两个或更多串口，其各自用途可通过 [sysctl(8)](/man/man8/sysctl.8.md) 标识。标识为“Modem”的端口具有正常的调制解调器接口，可与 PPP 一起使用。标识为“Diagnostic”的端口使用专有二进制接口，用于固件升级，此端口没有 AT 命令接口，无法用于控制设备。其他端口具有 AT 命令接口，可用于正常设备控制。

## 硬件

`uhso` 驱动应能与 Option 的大多数设备配合工作。以下设备已经过验证可正常工作：

* Option GlobeSurfer iCON 7.2（新固件）
* Option GlobeTrotter Max 7.2（新固件）
* Option iCON 225
* Option iCON 452
* Option iCON 505

该设备具有一个称为“Zero-CD”的大容量存储设备，其中包含 Microsoft Windows 的驱动程序；这是设备的默认模式。`uhso` 驱动会自动将设备从“Zero-CD”模式切换到调制解调器模式。可通过 [sysctl(8)](/man/man8/sysctl.8.md) 将 `hw.usb.uhso.auto_switch` 设置为 0 来禁用此行为。

**`/dev/cuaU?.?`**

## 实例

使用某个串口上可用的 AT 命令接口建立分组接口连接：

```sh
AT+CGDCONT=1,,"apn.provider"
AT_OWANCALL=1,1,1
OK
_OWANCALL=1,1
AT_OWANDATA=1
_OWANDATA: 1, 10.11.12.13, 0.0.0.0, 10.2.3.4, 10.2.3.5, e
	0.0.0.0, 0.0.0.0, 72000
```

配置接口：

```sh
ifconfig uhso0 10.11.12.13 up
route add default -interface uhso0
echo "nameserver 10.2.3.4" > /etc/resolv.conf
echo "nameserver 10.2.3.5" >> /etc/resolv.conf
```

可通过以下命令终止连接：

```sh
AT_OWANCALL=1,0,1
```

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/uhso.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.
