kasjer commented on issue #2196: Full console: suppress new line when echo is 
disabled

   Hi @dwld, I tell you why this takes so much time with such simple reasonable 
change.
   For a long time console code that was modified by a few people did not 
really handled few control characters resulting in some echo while console was 
configured to be silent except for NLIP protocol.
   In late 2019 I changed it so not echo for CR LF (and other control 
characters showed) but one company that uses mynewt was affected since they 
relayed on this not so obvious behavior.
   So 153dfb8b7d13f0cf16298fd6e3b5235909fe2f30 restored echo for CR/LF just as 
not to break `backward compatibility`.
   I probably should have add conditional code for allowing this echo if 
someone really needs it, instead of always, which is not something that would 
be expected from the code.
   So that is why no one is rushing to accept this.
