Pressing backspace does not bring the line back (it seems to invisibly delete the char backwards, though), but if I move backwards with left arrow and press ctrl-d, the line gets echoed and the character is erased as it should be. > Also, when you need to type two returns to get it to work, do both > show up in the transcript as ^M or only one?

I will try script, TTY_NEEDS_DRAINING and the TERMCAP ASAP, I'll report the result.
