Command for simulating "enter" button from the user - linux

Question

I'm looking for a way in tcl expect to simulate pressing "enter" the script (for example after some outputs the script stops, and only after I manually press "enter" it goes further) It wait's for a "enter" key to be pressed from the user before continuing outputting the remaining script.
Here is my code where I have this problem:
set timeout 20
set f [open "password.txt" r]
set password [read $f]
close $f
foreach i $password {
puts "trying this as a pass : $i"
spawn ssh user#exemple.net -p 724
expect "user#exemple.net's password:"
send $i
interact
}
This code takes from the password.txt all the words it contains and trye's them as the password for the user#exemple.net;
The code works but after this line from the code above expect "user#example.net's password:" I need to press manually "enter" button and then the script goes with the next try.
How can I simulate this enter. Is there any command that simulates it?
I am new to tcl expect. Thank you for your time.

Try to change
send $i
to
send "$i\n"
Use this code for example:
#!/usr/bin/expect
# Set the time allowed to wait for a given response. SEt to 30 seconds because it can take a while
# for machines to respond to an ssh request.
set timeout 30000
proc connectToServer { user host password port } {
set address $user
append address "#"
append address $host
puts "Connecting to server: $host"
spawn ssh $address -p $port
expect {
{*password: } {
send "$password\n"
interact
}
{The authenticity of host*} {
send "yes\n"
expect {
{*password: } {
send "$password\n"
interact
}
}
}
"*No route to host" { puts "No route to host" }
eof {puts "Woops there was an eof"}
timeout {puts "Timed out"}
}
}
if {$argc < 3} {
puts "Error - you need to provide at least 3 arguments"
puts "* user"
puts "* host"
puts "* password"
puts "* port - optional"
} else {
set user [lindex $argv 0];
set host [lindex $argv 1];
set password [lindex $argv 2];
# setting port argument is optional
if {$argc > 3} {
set port [lindex $argv 3];
} else {
set port 22
}
connectToServer $user $host $password $port
}
