ESC d00cursor delayedLF terminator

delayed LF: 0 = no change, 1 = disable delayed LF, 2 = enable delayed LF
Response: none
Description: Allows the host controller to disable or enable the OIT’s cursor or delayed
line feed. Anytime a LF character is received by the OIT, the delayed line feed feature
