STATUS LINE
The status line has several indicators, that speak for
themselves. The mysterious APP or NOR indicator probably needs
explanation. The VT100 cursor keys can be in two modes:
applications mode and cursor mode. This is controlled by an
escape sequence. If you find that the cursor keys do not work in,
say, vi when you're logged in using minicom then you can see with
this indicator whether the cursor keys are in applications or
cursor mode. You can toggle the two with the C-A I key. If the
cursor keys then work, it's probably an error in the remote
system's termcap initialization strings (is).
