TRint indirectly (via the Getline routines) changes your
tty settings to be able to do command line editing (raw mode).
On normal exit your original settings will be correctly
restored. However, if you crash out of ROOT your old
settings will not be restored. In such case try "tty sane",
or source a script that sets your tty back to the way you
like it.
Cheers, Fons.
