  • Page 29: Chapter 4. Host Commands

    PDS TERMINALS HAPTER HOST COMMANDS Introduction By design, the PDS allows a connecting device (or “host”) to control some of its functions by transmitting a string of special characters. Referred to as “Escape commands” (because each character string begins with the ASCII escape character), , these character strings enable the host to perform a variety of task including controlling the terminal’s cursor position, erasing the display lines and sounding beeps.
  • Page 30 Cursor Left Esc D Syntax Notes This command moves the cursor one position to the right. The cursor will not move beyond the start or end of a line, nor will it scroll the display. Cursor Home & Clear Display Esc E Syntax Enable Cursor...
