$t->print("\n");
Will send a new line. One of the issues you can run into when connecting to a console, is you never know what mode you will be in. Unlike telnet, a console will stay in config mode even if you disconnect. The way I usually deal with this is to send 2 ^C first, then send new lines until you get a response.
# set ors and errmode, save current values
$ors = $t->output_record_separator('');
$errmode = $t->errmode('return');
# send 2 ^C
$t->print("\03\03");
# keep poking it until we get a response
foreach (1 .. 20) {
last if $t->cmd(String => "\n",
Timeout => 1);
# give up and bail
die "could not get CLI prompt" if $_ == 20;
}
# reset ors and errmode
$t->errmode($errmode);
$t->output_record_separator($ors);
