I don't have such a system, but my starting assumption would be that micro-ODT
in general matches the behavior of standard ODT -- which is documented in
various software manuals.
Among other things, in ODT rubout isn't a character erase but a full cancel of
the command. So if you type 3 digits then rubout, whatever was underway is
canceled and you're back at the prompt.
