Notes on DECSSDT

• If you select no status line (Ps = 0), then the terminal uses the line as an additional user window line to display data.
• If you change from an indicator to a host-writable status line, then the new host-writable status line is empty.

• When you select the host-writable status line, most of the control functions that affect the main display also affect the status line. The following list describes the exceptions to the rule:

  Control Function	Action
  Select character set (SCS)	Both the main display and status line use the same character set.
  Cursor position controls	Only the column parameters in cursor-positioning commands operate in the status line.
  ANSI mode (DECANM)	Ignored if received in the status line.
  Set conformance level (DECSCL)	Exits the status line.
  Scrolling mode (DECSCLM)	Affects the main display and the status line.
  Soft terminal reset (DECSTR)	Exits the status line.
  Insert/replace mode (IRM)	Affects the main display and the status line.
  Hard terminal reset (RIS)	Erases and exits the status line.
  Tab stops	Affect the main display and status line.
  Autowrap mode (DECAWM)	Affects the main display and status line.

• DECSSDT does not affect the status line type displayed in Set-Up. In Set-Up, the terminal always uses the indicator status line.
