d 00 cursor delayedLF terminator
cursor:

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
causes the cursor to remain in its current position until the next displayable character is
received. The Set Cursor Position control command cancels the delayed line feed feature.
