我用HUAWEI E180 3G上网卡经过改一下支持E180的12d1.1414.ff 脚本后，再用以下命令能在友善的Tiny6410上连网
# 3g-ppp /system/etc/3g-modem/12d1.1414.ff
# call-ppp wcdma
但是当我用同样的方法在“华天正的6410”开发板上连网时却连接不上，现在我把这两种连网时的打印信息发出来，大家有兴趣的话可以帮分析一下，看是什么原因
1、在友善的Tiny6410上操作HUAWEI E180 3G上网卡
1.1、插入E180时

正常能连网时，执行 # call-ppp wcdma 是没有打印信号的
2、在华天正的6410上操作HUAWEI E180 3G上网卡
2.1、插入E180时

2.2、用# 3g-ppp /system/etc/3g-modem/12d1.1414.ff 进行拔号时
chat: invalid option -- 'f'
BusyBox v1.16.0 (2010-03-17 17:09:39 KST) multi-call binary.
Usage: chat EXPECT [SEND [EXPECT [SEND...]]]
Useful for interacting with a modem connected to stdin/stdout.
A script consists of one or more "expect-send" pairs of strings,
each pair is a pair of arguments. Example:
chat '' ATZ OK ATD123456 CONNECT '' ogin: pppuser word: ppppass '~'

2.3、然后用 # call-ppp wcdma 出现以下错误信息
# rm failed for /var/run/ppp0-ok, No such file or directory
rm failed for /var/run/pppd2.tdb, No such file or directoryinit: untracked
pid d
呵呵，以上有点长，也写得有点乱，我搞了好几天了也找不出是什么问题
（注：我是按着友善Tiny6410来改的其中改了pl2303.c还有加进了3g-device.c文件，在make menuconfig里的配置也同样跟着改，我觉得拔号脚本是没问题的，感觉问题是出现在内核，华天正6410开发板用的内核是2.6.28.6版）
