All these are cursor movement (not characters are written - or overwritten).

\x1e is "home", takes the cursor to 1,1
\x09 is "right", moves the cursor to the right (but doesnt overrite anything)
\x0a is "down", moves the cursor down (some horizontal position)

And just while I'm on this topic:
\x08 is "left"
\x0b is "up" (same horizontal position)

The cursor wraps when it gets to its boundary, ie:
* If you are at position 40 and "right", you are on the next line at position 1
* If you are on the bottom line (24) and down, you wrap to the top line (same col).

And thus, if the cursor is at 40,24 and "right", it wraps to 1,1.
