I'm assuming you're using @pattern_list to hold the return values from expect() like this:

@pattern_list = expect "SWBKPT hit for SLOT";

If that is true, then $pattern_list[0] is the "matched pattern position", $pattern_list[1] is the "error" and $pattern_list[2] is the "successfully matching string". However, to debug this, we need all the values, which is why I asked you to use Data::Dumper.

If you want to print the array values without Data::Dumper, then do something like this:

my @arr = qw( bob sue jane);
print "\@arr = " . join(':', @arr) . "\n";

Run example: 
my@mybox:~/sandbox
$ ./4.pl
@arr = bob:sue:jane

The reason all the values are important is because if $pattern_list[4] ("after match") has a value, then that probably means Expect is sending the "\n" before your console program is reading input.

Actually, you know what would be a quicker test of that? Insert a sleep() between your expect() and send() like this:

$expect->expect($timeout,"SWBKPT hit for SLOT");
sleep 2;
$expect->send("\n\n");

Of course, this test assumes that it takes less than 2 seconds between when the console program prints "SWBKPT hit for SLOT" and when it prints "Cycles : 332".
