If you want to run the socket data flows n times every 12 hours, then you need to calculate the period, which is the inverse of the frequency.

i.e.: ntimes / 12hours
  = ntimes / 12 * 3600seconds
  = ntimes / 43200seconds
  period = 1 / frequency
  therefore period = ( 43200 / n )seconds

Using this little gem of basic mathematics, you can then proceed to recode your script:

use IO::Socket;
my $sock = new IO::Socket::INET("$remote_server:43") || 
               die $!;

my $n = 5; # do this 5 times every 12 hours
while (1) # loop forever
{
  print $sock "$data\r\n";
  my @output = <$sock>;
  $output = join('', @output);
  if ($output =~ /$no_match/gi) {
    &true;
  } else {
    &false;
  }

  # sleep for the PERIOD
  sleep( int(43200 / $n) );
}
