在RaspberryPi上连接华为E3372

Question

我试着用华为(e3372)的LTE盘上网。我安装了usb-modeswitch，ppp和wvdial。modewswitch工作正常。该设备安装在/dev/ttyUSB0上，我可以在这里发送AT命令。我想用wvdial连接，但它总是说“PPP守护进程已死:调制解调器挂断了电话(退出代码= 16)”我的wvdial命令的控制台打印是：

我的wvdial配置文件：

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0
Init3 = AT+CGDCONT=1,"IP","drei.at"
Modem Type = Analog Modem
Baud = 9600
New PPPD = yes
Modem = /dev/ttyUSB0
ISDN = 0
Phone = *99#
Password = ;
Username = ;
Stupid Mode = 1
Dialer Attemps = 2
Carrier Check = off

是什么原因导致ppp守护程序挂起？

这是一个有点老的话题，但我想贡献一下，因为我发现自己在这个特定的调制解调器上遇到了麻烦，我在这篇文章中也看到了使用ttyUSB0的问题，如果有人再次遇到同样的问题:试着改用ttyUSB1。调制解调器作为两个设备通信，都接受命令，但ttyUSB0不仅挂断，而且还冻结调制解调器！
