To talk  to  someone  here  at  SAIL,  at  monitor  level  type  TALK
TTY<TELETYPE  NUMBER>  (no spaces between TTY and teletype number) or
TALK CTY if you wish to reach anyone, as we do not have  an  operator
here.  If the terminal is at monitor level, you will then become part
of what is known as a talk ring, in  which  everything  you  type  is
echoed  on  each terminal in the ring.  If terminal is not in monitor
mode you will get the error message BUSY. To leave a talk  ring  type
<control>C  (or  <CALL> on displays). If the person you are trying to
reach is always  busy,  Type  SEND <initials>   at  monitor level and
follow  instructions.   ( "initials"  is  his login programmer name.)
