From your AutoCAD Help file.

 

CMDECHO

Controls whether prompts and input are echoed during the AutoLISP command function.

 

MSasu wrote this when a similar question was posed back in 2010...

 

"This variable will allow (CMDECHO = 1) or prevent (CMDECHO = 0) display of commands prompts on AutoCAD text window.

It is used in AutoLISP routines to don’t annoy user with a cascade of strings on command prompt."

 

I think that should clear up any confusion on your part.
