   When I run micro-emacs, it needs to switch to getting   
   keystrokes from the user without the OS echoing the   
   characters and without waiting for a complete line to   
   be obtained.   
      
   In Unix there is an ioctl call to switch to that mode. On   
   Windows there is a SetConsoleMode function:   
      
   https://docs.microsoft.com/en-us/windows/console/setconsolemode   
      
   On MSDOS it appears that the application is instead   
   meant to stop doing a read() call and basically do an   
   INT 21H that is get_char_immediate_without_echo().   
      
   I'm wondering if there is some underlying principle that   
   says which of those 3 approaches is technically the best.   
   How do you compare APIs?   
      
   Thanks. Paul.
