Motor on: of course, "carrier detect" (mark) or data transition (mark ->
space) is the best time.

Motor off: no need for explicit motor-off. Make motor-on a timer (say 30
seconds) and re-trigger it upon every character output to the teletype.
It'll timeout eventually, and avoid needless off/on when receiving
multiple bulletins etc.
