谁用过终端下的wvdial拔号程序

在控制台用wvdial拔号，当出现欢迎界面：
**************************************
*   welcome to beijing263  *
**************************************
please input username:
-->Looks like a login propt.
-->sending:263
-->don`t know what to do ! starting pppd and hoping for the best.
-->starting pppd at XXX  XXX  XXX 2002
本来输完用户名后应该提示输入密码的，但是怎么会出现don`t know what to do

呢。
