请教中兴MC2716 3G无线网卡拨号失败
开发平台：TQ2440LINUX版本：2.6.22.6
MC2716的驱动方式：使用内核默认的option驱动,已添加了模块的相关设备信息
接上无线网卡后打印出的信息：
usb 1-1: new full speed USB device using s3c2410-ohci and address 3
usb 1-1: configuration #1 chosen from 1 choice
option 1-1:1.0: GSM modem (1-port) converter detected
usb 1-1: GSM modem (1-port) converter now attached to ttyUSB0
option 1-1:1.1: GSM modem (1-port) converter detected
usb 1-1: GSM modem (1-port) converter now attached to ttyUSB1
option 1-1:1.2: GSM modem (1-port) converter detected
usb 1-1: GSM modem (1-port) converter now attached to ttyUSB2
option 1-1:1.3: GSM modem (1-port) converter detected
usb 1-1: GSM modem (1-port) converter now attached to ttyUSB3
上面说明驱动应该是成功的，并且创建了ttyUSB0-ttyUSB3，这4个节点。
然后使用中兴的拨号脚本拨号，提示的错误信息如下：
# pppd call evdo
Connect script failed
请问这个“连接脚本错误”是怎么回事，要怎么解决。
附上拨号脚本：
# /etc/ppp/chat/evdo
# this is the chat script for unicom
ABORT "NO CARRIER"
ABORT "NO DIALTONE"
ABORT "ERROR"
ABORT "NO ANSWER"
ABORT "BUSY"

试过了，模块的手册里面说明MC2716的ttyUSB0为modem ttyUSB1为AT.应该是脚本不对，官方的脚本难道不适合？ 最后发现C网信号显示的是99，说明网络不行，接上天线后拨号成功，结贴。
