  Same as new from L<Net::Telnet> but sets the default Trango Prompt:

  It also takes an optional parameter 'Decode'.  If not defined it
  defaults to 1, if it is set to 0, it will not decode the output and
  instead return a reference to an array of the lines that were returned

  =head1 ACCESSORS
  These are usually only set internally.
  =head2 B<firmware_version> - returns the firmware version
  Returns the firmware version if available, otherwise undef.
  It should be available after a successful open().
  =head2 B<host_type> - return the type of host you are connected to.
  returns the type of host from the login banner for example M5830S or M5300S.
  Should be available after a successful open().
  =head2 B<is_connected> - Status of the connection to host.
  returns 1 when connected, undef otherwise.
  =head2 B<logged_in> - Status of being logged in to the host.
  returns 1 after a successful login(), 0 if it failed and undef if
  login() was never called.
  =head2 B<login_banner> - The banner when first connecting to the host.
  returns the banner that is displayed when first connected at login.
  Only set after a successful open().
  =head2 B<last_lines> - The last lines of output from the last cmd().
  returns, as an array ref, the output from the last cmd() that was run.
  =head2 B<last_error> - A text output of the last error that was encountered.
  returns the last error reported.  Probably contains the last entry in
  last_lines.
  =head1 ALIASES
  =head2 B<bye> - alias of exit()
  Does the same as exit()
  =head2 B<restart> - alias of reboot()
  Does the same as reboot()
  =head2 B<save_systemsetting> - alias of save_ss()
  Does the same as save_ss()
  =head1 COMMANDS
  Most of these are just shortcuts to C<cmd(String =E<gt> METHOD)>,
  as such they accept the same options as C<cmd()>.
  Specifically they take a named paramater "args", for example:
  C<tftpd(args =E<gt> 'on')> would enable tftpd
  =head2 B<tftpd> - The output from the tftpd command
  Returns a hash ref of the decoded output from the
  command.
  Also see enable_tftpd() and disable_tftpd() as those check that it was
  successfully changed.
  =head2 B<ver> - The output from the ver command
  Returns a hash ref of the decoded output from the
  command.
  =head2 B<sysinfo> - The output from the sysinfo command
  Returns a hash ref of the decoded output from the
  command.
  =head2 B<exit> - Exits the connection
  exits the command session with the Trango and closes
  the connection
  =head2 B<reboot> - Sends a reboot command
  reboots the Trango and closes the connection
  =head2 B<remarks> - Set or retrieve the remarks.
  Takes an optional argument, which sets the remarks.
  If there is no argument, returns the current remarks.
    my $old_remarks = $t->remarks();
    $t->remarks($new_remarks);
  =head2 B<sulog> - The output from the sulog command
  Returns an array ref of hashes containing each log
  line.
  =head2 B<save_sudb> - saves the sudb
  Returns true on success, undef on failure
  =head2 B<syslog> - The output from the sulog command
  Returns a hashref of the output from the syslog command
  =head2 B<pipe> - the pipe command
  Returns the output from the pipe command
  =head2 B<maclist> - retrieves the maclist
  Returns the output from the maclist command
  =head2 B<maclist_reset> - resets the maclist.
  No useful output.
  =head2 B<eth_link> - eth link command
  Returns the output from the eth link command
  This command seems to cause some weird issues.  It often will cause the
  command after it to appear to fail.  I am not sure why.
  =head2 B<su_info> - gets the su info
  Returns information about the SU.
  You need to pass in the $suid and it will return the info for that suid.
    $t->su_info($suid);
  =head2 B<su_testrflink> - tests the RF Link to an su
    $t->su_testrflink($suid|'all');
  =head2 B<save_ss> - saves the config.
  Returns 1 on success, undef on failure.
  =head2 B<opmode> - sets opmode ap y or returns the opmode
      $t->opmode([ap y]);

  =head2 B<cmd> - runs a command on the AP.
  This does most of the work.  At the heart, it calls Net::Telnet::cmd()
  but it also does some special stuff for Trango.
  Normally returns the last lines from from the command
  If you are using this, rather than one of the "easy" methods above,
  you probably want to read through the source of this module to see how
  some of the other commands are called.
  In addition to the Net::Telnet::cmd() options, it also accepts these:
  I<decode>
  - if this is true, then it will send the output lines to _decode_lines()
  and then returns the decoded output
  I<no_prompt>
  - if this is true, it does not wait for a prompt, so you are not stuck
  waiting for something that will never happen.
  I<cmd_disconnects>
  - if this is true, it then sets logged_in() to false, then it will
  close() the connection and set is_connected() to false
  I<expect>
  - if this is set (usually to 'Success.') it will check for that in the
  last line of output and if it does not, will return undef because the
  command probably failed
  I<args>
  - a string containing the command line options that are passed to the
  command
      $t->cmd( String => 'exit', no_prompt => 1, cmd_disconnects => 1 );
