    Found a modem on /dev/ttyUSB0.
    Modem configuration written to /etc/wvdial.conf.
    ttyUSB0: Speed 9600; init "ATQ0 V1 E1 S0=0 &C1 &D2"

上面的细节说我可以使用 ttyUSB0 或 ttyUSB2 发送短信

/etc/wvdial.conf


    [Dialer Defaults]
    Init1 = ATZ
    Init2 = ATQ0 V1 E1 S0=0 &C1 &D2
    Modem Type = Analog Modem

要通过调制解调器发送短信，需要切换到 gsm 文本模式。 wvdial.conf 属性必须更新如下：


    [Dialer Defaults]
    Init1 = AT
    #
    Init2 = AT+CSCS="GSM"
    # Set the GSM modem in SMS Text Mode
    Init3 = AT+CMGF=1
    # Get info about the current operator.
    Init4 = AT+COPS?
    # To check whether the GSM/GPRS modem or mobile phone supports SMS text mode, 
    Init5 = AT+CMGF=?
    # Display the currently active modem mode.
    Init6 = AT^GETPORTMODE
    # : 1,1,1  : SMS text mode send, receive, boradcast supported
    Init7 = AT+CSMS=1
    # Device model Number
    Init8 = AT+GMM
    # 31, 3207880  : First number is signal strength, 0...31 where 31 is maximum possible. 2nd number  = ?
    Init9 = AT+CSQ
    # 0,0  : means the modem i snot connected to the network
    Init10 = AT+CREG?
    # 1 : means CDMA digital service available(0=no service, 2=TDMA, 3=analog)
    Init11 = AT+CAD?
    # should have said what storage memory is available for SMS
    Init12 = AT+CPMS=?

    # Type of the modem.
    Modem Type = Analog Modem
    # The location of the device that wvdial should use as your modem.
    Modem = /dev/ttyUSB0
    ISDN = 0
    Baud = 9600
    Dial Attempts = 3

保存以上属性后，wvdial 将正常工作...

在下面的文件中，您将看到所有属性的详细说明 https://github.com/morfikov/files/blob/master/configs/etc/wvdial.conf
