When watching a terminal, it is desirable to set the proper modes on the
  watcher's terminal before displaying output from the watched terminal.

  Ideally, the watcher's terminal should have the same modes set as the
  terminal which is being watched. This ensures the output will display
  correctly.

  This is not a problem when using Peek/Spy's initial-screen-display
  feature since the correct initial settings for the watcher's terminal
  will be output to it as part of the initial-screen display.

  However when the screen-saver is NOT in use by the person being
  watched, it may be desirable to set some initial terminal modes on
  your terminal before you begin watching. In addition you may also
  want to restore your own terminal modes when finished watching another
  terminal.

  The Peek/Spy /INIT_SEQUENCE=() qualifier may be used to specify
  an initial modes-setting sequence which is sent to your terminal just
  before you start watching. The /FINISH_SEQUENCE=() qualifier
  specifies a modes-setting sequence which will be sent to your terminal
  after you finish watching someone.

  Each of these qualifiers accepts a list of keywords. Each keyword
 causes a particular sequence to be sent to the watcher's terminal.
