   Also accepts these options:
   
   I<decode>
   - if this is true, then it will send the output lines to _decode_lines()
   and then returns the decoded output
   
   I<cmd_disconnects>
   - if this is true, it then sets logged_in() to false, then it will
   close() the connection and then sets 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
