急！pppd启动失败的问题！（实达外猫)

pppd启动失败的问题！（实达外猫)
在mdk9.1下，用kppp拨号。设置kppp顺利，在拨的时候，到了正在登陆网络这一步就停了。报错是pppd启动接口失败。
看了日志，和运行情况，说是：
Couldn't find interface ppp0：No such device
我试了在其他linux，都这样。
请问怎么解决？
猫是实达之星 5600 DB+ 外猫 lockwell 芯片

老兄？怎么搞？我是用201上网的。
难道没有仁兄碰到过这种事？

不过很怪，我用别的猫拨，就行。(用的是联想射调I)
我比较了两者的不同：
#kppp 拨号后

请问这是怎么回事？难道实达猫本身就不支持linux？
但却能拨号。真是怪事阿！
或是那里设置错误？谢了
我的系统用的是mdk9.1 还有一个网卡(pci)，猫的串口有2个。
