Device Status Report (DSR)

Request information from the terminal.

  1. 0x1B
    ESC
  2. 0x5B
    [
  3. ____
    n
  4. 0x6E
    n

Request information from the terminal depending on the value of n.

The possible valid values of n are described in the paragraphs below. If any other value of n is provided, this sequence does nothing.

If n = 5, the operating status is requested. The terminal responds to the program with ESC [ 0 n to indicate no malfunctions.

If n = 6, the cursor position is requested. The terminal responds to the program in the format ESC [ y ; x R where y is the row and x is the column, both one-indexed. If origin mode (DEC Mode 6) is enabled, the reported cursor position is relative to the top-left of the scroll region.
