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.

the pppd server runs well. and the scripts runs well on my redhat9.0.
this problem seems to be resolved by adding a option ,-mn,but the
-mn? Option to what?
other problem is coming ,

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
