What is CARD?

Do you really expect a login/password prompt? Most ISPs use PAP or
CHAP authentication done within PPP negotiation. If you are not trying
to establish an ISP connection then describe exactly what you are trying
to do.

If you are not sure about the prompt then add the pppd option
"user Your_ISP_Username" and configure both of the files
/etc/ppp{pap,chap}-secrets with the line

Your_ISP_Username * Your_ISP_Password

Also replace the chat-lg script lines

> CONNECT ''
> ogin:--ogin: CARD
> password: CARD

with the single line

CONNECT \d\c

This line adds a 1-second delay before starting pppd and prevents chat
from sending a carriage-return which can cause trouble with some ISPs,
triggering a login prompt (apparently not the case here), or a menu to
be presented at the remote end.

You don't need

and setting

isn't recommended, especially mru.

The novj is probably not necessary either.

Adding a modem initialization string you know should work is recommended.

The remote doesn't present a login prompt (at least not one ending in
"ogin:"). What does minicom show when you call the same number with it?

You aren't getting a login: prompt. Are you sure the host doesn't use
PAP or CHAP? Do you see a "login:" if you use minicom?

It display automaticly in minicom after initializing,
I think it is caused by my init string ,which is configured using minicom -s
And I did as your said(I do really need an ISP connection!):
1,add the pppd option "user CARD"
2,configure both of the files /etc/ppp{pap,chap}-secrets with the line
"CARD" * "CARD"
3,Also replace the chat-lg script lines
> CONNECT ''

with the single line

CONNECT \d\c





There was a big progress with this method, but I encouterd a new problem
Following section is my /var/log/debug
I hope i need not recompile the kernel, because after I recompiled the 2.6.5
kernel,
minicom cannot detect /dev/usb/ttyUSB0

Okay, then it's not a stored profile that could be easily used by pppd
(e.g., AT&F, AT&F1).

Again, what is CARD? It would be unusual for both an ISP user name
and password to be the same. And also again, if something special is
being attempted then please explain.

Pppd found it. Was 2.6.5 running when the log below was generated?

Here pppd rejects CHAP authentication requested by the peer.

What followed showed that was the only authentication method the peer
would accept. The peer is broken as evidenced by the fact that it did
not send a Terminate-Request but instead hung in until IPCP reached the
open state on your host with no IP addresses assigned. Ugh.

Then pppd requested Termination, and the peer agreed.

I'm not sure what's happening. With the user option and the secrets
line CHAP should have been accepted even if it subsequently failed.
Maybe "refuse-chap" or the old version of that option, -chap, in
a privileged options file?

Add the pppd option dryrun and post the output.

I have to admit that i had made some mistakes-----I missed option user CARD
in pppd
login:CARD
password:CARD
is really the u/p of the carrier in our country.

NOW everything goes well, Thank you very much.
