Thanks BrowserUk

I thought that by closing the handler it will automatically end the child process, but I ended up the other way around, I killed the child process an I don't even need to close the handle, this is how I worked out:

#!/usr/bin/perl

$SIG{INT} = \&end;

my $kid = open (TELNET, '-|', "telnet 192.168.1.1 6088");

while(<TELNET>) {
    $arr = <TELNET>;
    $arr =~ s/[\r\n](.....):(.*)/<p class="$1">$1:$2<\/p>/;
    print $arr;
}
end;

sub end {
    kill 9, $kid; ## Or whatever signal is appropriate!
    print "Session closed!\n"
    exit;
}

But actually I am moving forward now, this version didn't work on Active Perl, I am looking for something that would support as much platforms as I can.

Now instead of use the pipe I use the IO::Socket::INET library with the recv subroutine, but since it is lower level I am having some troubles parsing the lines :P.

Anyways thanks for the help, now this script is helping me a lot for my work.
