   Any version of DOS will appear to hang in RAW mode if asked to get a line 
of text from the keyboard.  Since carriage return is not treated specially 
in RAW mode, DOS simply gets characters until the buffer fills.
   Thus if you simply put a brick (I used the DOS manual) on the Enter key
for about thirty seconds, the buffer will fill, DOS will return, and LINK
will report 'Response line too long' and exit to COMMAND.
   While leaving the console in RAW mode outside of applications isn't a 
great idea, at least it doesn't truly crash DOS.
