问题描述
我正在编写一个 C++ 应用程序来管理我的 arm 板上的调制解调器连接。我想为此使用 wvdial 实用程序。不幸的是，我有一个问题。当启动“wvdialconf”时，检测到调制解调器并初始化文件“wvdial.conf”。
# sudo wvdialconf
Editing `/etc/wvdial.conf'.
Scanning your serial ports for a modem.

Found a modem on /dev/ttyUSB0.
Modem configuration written to /etc/wvdial.conf.
ttyUSB0<Info>: Speed 230400; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"
我的“wvdial.conf”文件：
[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CGDCONT=1,"IP","myapn"
Stupid Mode = 1
Modem Type = Analog Modem
ISDN = 0
New PPPD = yes
Phone = *99#
Modem = /dev/ttyUSB0
Username = " "
Password = " "
Baud = 230400
但是当我尝试运行“wvdial”或“wvdial -c”或“wvdial”时
# sudo wvdial
--> WvDial: Internet dialer version 1.61
--> Warning: section [Dialer Defaults] does not exist in wvdial.conf.
--> Cannot open /dev/modem: No such file or directory
--> Cannot open /dev/modem: No such file or directory

--> Cannot open /dev/modem: No such file or directory
--> Cannot open /dev/modem: No such file or directory
不幸的是，我不知道。配置文件存在但 wvdial 看不到它。我不知道这是否重要，但我在路径“/etc/ppp/”中没有文件“pap-secrets”和“chap-secrets”
