Why is this expect shell script to ssh into and reboot cisco appliances failing? -

created simple script perform reboot on cisco (telepresence) cts1300, 1000 , 3000 codecs. goal restart bunch of these units weekly through use of cron. using cygwin, , here's expect script:

#!/usr/bin/expect -f spawn ssh adminuser@123.123.123.123 expect "*?assword:*" send -- "mypassword\r" expect "*admin:*" "send -- "utils system restart\r" expect -exact "are sure want perform system restart ?\r enter \"yes\" restart system or other key abort\r continue: " send -- "yes\r" expect "*admin:*" send -- "quit\r" expect eof 

the output is:

superuser@superpc ~/ctspsswd  ./restartall2 spawn ssh adminuser@123.123.123.123 adminuser@123.123.123.123's password: command line interface starting up, please wait ...  welcome telepresence command line interface (version 1.1) admin:utils system restart sure want perform system restart ? enter "yes" restart system or other key abort continue: s system restart has been aborted admin:quit connection 123.123.123.123 closed. 

for weird reason, sends "s", aborts system restart.

i tried using #!/bin/bash type scripting , output similar.

i tried using wild chars expect "*continue:*" , still similar output.

i tried using autoexpect , same exact thing happens. autoexpect script looks similar script, more specific each character typed.

i tried sending yes after sending utils system restart, , result equivalent of \r.

is there i'm missing? otherwise, i'll create script use interact yes portion.
