As a side note (because i do understand the usefulness of your desired output) some general suggestions:
$ip = "";
$port = "";
$usr = "";
$port = "";
$status = "";
$frequency = 0;
is unneeded and error prone because reveals the absence of
use strict; use warnings; In fact in a more concise, more robust, less error prone way you can say:
my ($ip,$port,$port,$status,$frequency);
Read this post to understand why. In Perl, given your variable declaration, you can freely do the following:
#string? #number? #add to string? #concatenate to numb
+ers?
my $ip=""; my $freq = 0; $ip++; $freq.="still no data
+";
