Debugging

       The typical usage bug causes a time-out error because you've made
       incorrect assumptions about what the remote side actually sends.  The
       easiest way to reconcile what the remote side sends with your expecta-
       tions is to use "input_log()" or "dump_log()".

       "dump_log()" allows you to see the data being sent from the remote side
       before any translation is done, while "input_log()" shows you the
       results after translation.  The translation includes converting end of
       line characters, removing and responding to TELNET protocol commands in
       the data stream.
