NEL (Next Line) moves the cursor to the beginning of the next line. The sequence is
ESC E. Equivalent to a carriage return followed by a line feed (CR + LF). If the cursor is at the bottom margin, the content scrolls up.How this is testedautomated
Write "ABC" then send
Write "ABC" then send
\x1bE (NEL), verify cursor is at row 1, col 0.The same probe runs against headless backends (via Termless) and real terminal apps (via a daemon launched in each terminal). This lets us distinguish parser correctness from rendering correctness.
