Hi Wei,
:) Thanks Champ!!! Thanks a lot for your help and sincere efforts!!!!

Everything is fine now.
The following statement of yours does wonder for me:
===========================
I notice that you need to login to NUT everytime when you using cu,
so I think this is the key problem. after run command on NUT, NUT
force(?) you logout, and we know, if we logout, all our process will
be kill. So you should config your NUT to not logout you cu.

config by cu -l ttyS0, the first cu need to login, and the second does
not need.

# cu -l ttyS0
Fedoar12NUT login:
...
# cu -l ttyS0
Connected.
==========================

For some reason, mingetty was not working properly on my NUT machine
so i used agetty.
But agetty was forcing to log out the connection. I again tried to use
mingetty and now its working.

Everything is working fine now. You gave a lot of time to me which is
highly appreciable.

Thanks,
Arif
