Qualifiers

/SCROLL
      /SCROLL
      /NOSCROLL

   Determines how new lines of text are displayed on the screen
   when the viewport becomes full. If /NOSCROLL is specified, the
   text lines are wrapped and new text appears on the top line of
   the viewport. /NOSCROLL improves the response time for terminals
   operating at slow speeds.

   If /SCROLL is specified, the text is scrolled up one line each
   time a new line of text is entered. The new line appears at the
   bottom of the viewport. /SCROLL is the default.


/SWITCH_HOOK
      /SWITCH_HOOK="character"

   Specifies the Phone Utility switch-hook character (%).  The
   switch-hook character must be entered before each Phone utility
   command that is entered during a conversation.

   PHONE commands are terminated by pressing RETURN or by entering
   the switch-hook character. Text typed without the switch-hook
   character is considered part of the conversation. You can use
   any nonalphanumeric character as the switch-hook character.
   Enclose the character in quotation marks. The default switch-hook
   character is the percent sign (%).


/VIEWPORT_SIZE
      /VIEWPORT_SIZE=n

   Specifies the maximum number of lines in a viewport, including
   the heading line and the bottom line of dashes. The valid range
   is 3 to 10 lines. Smaller viewports will improve the response
   time on terminals operating at slow speeds. The default viewport
   size is automatically reduced as more participants enter the
   conversation.
