Ok, Try this:
Code:
#!/usr/bin/expect
set timeout 10
set host     [lindex $argv 0]
set user     [lindex $argv 1]
set password [lindex $argv 2]

proc login {host user password} {
  expect {
    "nkown host"                        { puts "***Host($host) is unkown."; return 1 }
    "onnection refused"                 { puts "***Connection was refused to host($host)."; return 1 }
    "Escape character is '^]'."         { exp_continue }
    -re "Login:.*$|login:.*$"           { exp_send "$user\r"; exp_continue }
    -re "Password:.*$|password:$"       { exp_send "$password\r"; return 0 }
    timeout                             { puts "***Telnet timed out waiting for host($host)."; return 1 }
  }
}

catch { spawn -noecho telnet $host }
set login_results [login $host $user $password]

# If successful connection, continue, else exit denoting error occured.
if { $login_results == 0 } {
  puts "\r***Connected; You are on the command line..."
  interact
  # Successful telnet session so exit with zero status
  exit 0
}
# Error connecting to host so exit with non-zero status
exit 1
