Sl8082 padlisten problem

I was able to excute tcp server on sl8082 using pad command:

AT!PADLISTEN?1

!PADLISTEN:

Profile 1: 1
OK

Then i try to connect using tcp-client, it was able to connect but then quickly closed by sl8082,
i am trying to modif parameter using PADSETUP and PADCONF but no good
