  
 		TERMINAL CONTROL COMMANDS
  
    Control characters are special characters produced by holding
 down the CTRL key and striking some other keyboard character.  These
 special characters can be used to control the output to or input from
 the terminal.  In general if a command requires that the CTRL key be
 held down its presence is signified by a ^ preceding the letter.

  
	HELP is available on the following qualifiers

	Type  HELP CONTROL qualifier for more information.
2	RUBOUT

 Each time the RUBOUT key is hit the previous character in the line
 is deleted.  Note that it will only be visibly rubbed out on a screen
 if the terminal is set as a CRT (see SET).
  
 
2	^U

 Typing ^U deletes the entire line.
  
 
2	^R

 Typing ^R retypes the current line with rubouts removed.
  
 
2	^O

 Typing ^O stops the current output to the terminal until another ^O
 is typed.  All output sent to the terminal in between is lost.
  
 
2	^S

 Typing ^S suspends output to the terminal, but no output is lost.
  
 
2	^Q

 Typing ^Q resumes output to a terminal suspended via ^S.
 
  
2	^C

 Typing ^C will request MCR (and give you an MCR> prompt) even
 if your terminal is currently busy.
 
2	^Z

 ^Z is the exit command for terminating most system utilities.
  
2	^X

 For systems with the full-duplex terminal driver, ^X empties the
 typeahead buffer for the terminal.
