调制解调器 PPP:调制解调器未响应 ModemCmd 上的“AT”:标签

我正在尝试在 pfSense 中安装 3g 调制解调器,即华为 e173,但让它通过它进行通信似乎很复杂。

在接口/接口分配/PPP中安装3g调制解调器后,

我回到接口/接口分配并添加了一个新接口,

之后,我进入状态/接口并意识到我无法连接它,因此我检查状态/系统日志/PPP 日志并发现存在此错误,但无法弄清楚原因,因为该调制解调器是兼容的:

 Mar 3 15:22:40   ppp      [opt5_link0] Link: reconnection attempt 7 in 1 seconds
Mar 3 15:22:41   ppp      [opt5_link0] Link: reconnection attempt 7
Mar 3 15:22:56   ppp      [opt5_link0] CHAT: The modem is not responding to "AT" at ModemCmd: label.

Mar 3 15:22:56   ppp      [opt5_link0] LCP: Down event

从我插入此调制解调器时显示的 3 个接口链接(cuaU0、cuaU1 和 cuaU2)来看,关于来自 cuaU0 的错误,在 cuaU0 中有这个:

Mar 3 15:27:40   ppp      [opt5_link0] Link: reconnection attempt 1 in 2 seconds

在 cua01 中:

MODEM: Fail to open serial port /dev/cuaU0 on speed 115200

在控制台中我有以下设备:

<HUAWEI Mobile HUAWEI> at usbus0, cfg=0 md=HOST spd=            HIGH (480Mbps) pwr=ON (500mA)

  bLength = 0x0012
  bDescriptorType = 0x0001
  bcdUSB = 0x0200
  bDeviceClass = 0x0000  <Probed by interface class>
  bDeviceSubClass = 0x0000
  bDeviceProtocol = 0x0000
  bMaxPacketSize0 = 0x0040
  idVendor = 0x12d1
  idProduct = 0x1c05
  bcdDevice = 0x0102
  iManufacturer = 0x0002  <HUAWEI>
  iProduct = 0x0001  <HUAWEI Mobile>
  iSerialNumber = 0x0000  <no string>

任何人?

检查兼容列表后(https://doc.pfsense.org/index.php/Known_Working_3G-4G_Modems)我注意到这个版本不兼容。

只是想让大家知道,这个版本是华为 E173S-1idProduct = 0x1c05

此 idProduct 是通过控制台使用以下命令行提取的:

usbconfig dump_device_desc
