thanks,the problem has been resolved.
for long time,i have take no notice of the chat scripts(because i had
thought it correctly),
on my board,uclinux doesn't surpport one command,multi-lines by '\'
in fact ,chat negotiations didn't been started.
now i changed the scripts :
#!/bin/sh
exec /bin/chat -v '' AT OK ATDT*99***1# CONNECT ''
the pppd has been started
In many situations you should end with '\d\c' so that your chat script does
not send a carriage return, which it does for '' which you use to end it.
Many isps see taht carriage return as a request to start a regular login
session rather than ppp. However in your case I guess it is a gsm phone or
something you are using.

Notice that the line you receive is identical to the line you sent. You
are
receiving your own replies. A very common reason for this is that you
forgot and sent a carriage return to the far side before you started ppp.
You do not show us the prior negotiations-- ie the output from chat-- top
see what you sent.
If you are using chat, terminate the last chat string with
\d\c Ie, a one second pause and do not send a carriage return.
Of course you might have miswired your serial cable and wired the output
to
the input. but that is unlkely unless you wired your own cable.
It could also be that your modem is echoing back everthing.

You are STILL repeating yourself. That option did absolutely nothing.

Yes, stop talking to yourself.
You might want to look at www.theory.physics.ubc.ca/ppp-linux.html for
hints at debugging your ssytem.
