expect: exit on no action from programs' side -

I have the following script to execute a command on a remote device on ssh:

  #! / Usr / bin / expect -f set cmd $ argv set timeout-1 spawning ssp-p22 user @ 1 9 82.1.1 match_max 100000 "* * Expected to announce: *" Send "PASS" Expected "& lt; * "Send $ CMD \ r is expected" *: "On the previous line," Y \ R "can be expected  

To exit my script" File " End "though the remote device never sends" end of file ", even if the communication is over. Is there any possibility of exit from some type of inactivity timer? Something like this:

  expected feof for 10 seconds  

Set the timeout variable eof not feof

Use

to set the "Y \ R" timeout is expected {timeout {send_user "$ timeout after seconds is not EOF" exp_close} eof}
