DEPRECATED: does not have any effect any longer. Login looks up wether new method is possible and falls back to old method. This parameter will be removed in future.
Auth method changed in RouterOS v6.43+ (https://wiki.mikrotik.com/wiki/Manual:API#Initial_login) and reduces login by one call but sends password in plaintext.

=head2 $api->get_probe_before_talk(), $api->set_probe_before_talk( $seconds )

Use this attribute to enable a test command with timeout to ensure that the connection is still alive before sending the actual command.
This is very useful for long lasting connections that may get disconnected while idling. A broken connection will not be recognized otherwise,
because the socket still exists and the command will last forever. The advantage over a common timeout for all commands is that long lasting
commands are still possible. Set this to 0 if you use many consequent commands and reenable it after completion.

    $api->set_probe_before_talk(0); # no probing of connection before sending command and read reply
    $api->set_probe_before_talk(5); # a simple command will be sent and after 5 seconds of no reply, the connection is assumed as broken

=item *

Use of Moose for OO

=item *

higher compilation time of Moose based lib negligible because of slow I/O operations

=item *

Moose is more common than Moo or similar

Please report any bugs or feature requests to C<bug-mikrotik-api at rt.cpan.org>, or through
the web interface at L<http://rt.cpan.org/NoAuth/ReportBug.html?Queue=MikroTik-API>.  I will be notified, and then you'll
automatically be notified of progress on your bug as I make changes.

=head2 Known issues

=item *

Quite high compile time because of using Moose. Use of a persistent running framework recommended.

=item *

Login to RouterOS v6.43rc* not possible because of a changed auth method using plaintext passwords

=item *

Add a parameter talk_timeout as an alternative for probe_before_talk that enables an actual timeout for each command.
