Логировать последовательный порт с Mikrotik?

Ты можешь использовать Linux и этот Perl-скрипт: #!/usr/bin/perl
#
# Serial port data receiver (logger)
# Receives at any speed without data loss and uses practicaly no CPU

use Device::SerialPort;
use Time::HiRes "usleep";
my $port = '/dev/ttyS0';

my $ob = Device::SerialPort->new ($port);

$baud = '2400';
$parity = 'none';
$data = '7';
$stop = '1';
$hshake = 'none';

$ob->baudrate($baud)    || die "fail setting baud";
$ob->parity($parity)    || die "fail setting parity";
$ob->databits($data)    || die "fail setting databits";
$ob->stopbits($stop)    || die "fail setting stopbits";
$ob->handshake($hshake) || die "fail setting handshake";

# Open the file where all data will be logged
open(LOG, ">>/opt/logger/logs/logfile.log") || die "Cannot open logfile";

# Nonbuffered output to file !
select(LOG), $| = 1;

# Endless loop
while (1)
{
   # Get data from serial port
   $stream = $ob->input;

   # If the variable contains data, process it else sleep
   if ($stream)
   {
       print LOG $stream;
   }
   else
   {
       usleep(1);
   }
} But MT could do it, that was greate due routerboard size
