总算装好ubuntu 8.04
就是神州数码DCWL-390不能拨号，查了一些资料，还是搞不定，特此向高手求助!
动行sudo gedit /etc/wvdial.cong,内容如下:
[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem
ISDN = 0
New PPPD = yes
Phone = #777
Modem = /dev/ttyS0
Username = CARD
Password = CARD
Baud = 115200
这里说明一下，原来显示的有些不同，这里列出:
; Phone = #777
; Username = CARD
; Password = CARD
两种不同的配置文件拨号都不能成功，以下是以第一种配置运行sudo wvdial显示的内容:
