simulate enter keypress after a command is executed

I am doing SSH to a host and executing a command and the command asks you to press the enter key. (It asks twice for different things.)

I am using spawn expect here.

When you send the report command, it will ask for you to press ENTER key. Once that is done, again it asks you to press enter. I want to send the enter key automatically.

#!/usr/bin/expect
spawn ssh user@host report
expect "Press ENTER to continue, or CTRL-C to quit."
send " \r"
expect "Press enter for inputing"
send "\r"

ENTER should be done automatically and get the end result of the command.

say you have the "report" script on machine "audrey":

#!/bin/bash
echo -n "Press ENTER to continue, or CTRL-C to quit."
read
echo -n "Press enter for inputing"
read
read s
echo "You sent: $s"

and the local expect script:

#!/usr/bin/expect
spawn ssh audrey ./report
expect "Press ENTER to continue, or CTRL-C to quit."
send "\n"
expect "Press enter for inputing"
send "\n"
send "OK\n"                                                                           
expect "You sent: OK"
close

./a.expect output:

spawn ssh audrey ./report
Press ENTER to continue, or CTRL-C to quit.
Press enter for inputing
OK
You sent: OK
