Exits from the Phone utility. When you enter this command, the
    HANGUP command is executed and you are returned to the DCL
    command level prompt. (You can also use Ctrl/Z when there is
    no conversation.)

    Format

      EXIT

1  –  Example

  %DIAL PETERS
     .
     .
     .
  %HANGUP
  %DIAL FENTON
     .
     .
     .
  %EXIT
  $

      This example illustrates the difference between the two Phone
      commands HANGUP and EXIT. At the first Phone prompt, Peters is
      dialed. The phone connection to Peters is terminated with the
      HANGUP command, but the user is still in the Phone utility. The
      phone connection to Fenton is terminated with the EXIT command,
      which causes an exit from Phone and a return to DCL command
      level. (Ctrl/Z could have been used instead of the HANGUP.)
