The PK program can be used to PeeK at the input and output buffers of
any terminal.  (If the terminal is a display, the line editor buffer
is also shown.)  To run PK, give the monitor command "R PK".  PK will
ask for a terminal number, and display that terminal's buffers.  It
also displays the contents of some of the internal system variables
associated with the terminal, and the who line of the job using the
terminal, if any.

If the selected terminal is hidden (by ESC H), PK will so notify you.
You may choose to override the hiding, but if so, the selected terminal
is notified that you are spying on it.

If you are using a SAIL display, the selected terminal's buffers will
be displayed on your screen about once per second, like a WHO display.
If you are using a non-display, the PK information will be typed once.
On a display, to show another terminal's buffers, just type its line
number followed by return.  To exit, just type return by itself, or
type any monitor command.  The last buffer display will remain on your
screen until you reset your display by BREAK P or by running another
program.
