   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

   =head1 TODO
   
   There are still a lot of commands that are not accessed directly.  If
   you call them (as cmd("command + args") or whatever) and it works,
   please send me examples that work and I will try to get it incorporated
   into the next version of the script.
   
   I also want to be able to parse the different types of output from
   commands like su, sudb all and anything else that would be better
   available as a perl datastructure.
