 * in 'raw' mode, if we want to be able to fetch a single character. This also means that everything must be put back
 * correctly when the program ends.
 *
 * For interactive use of SRUN/SDBG if would be much better to use GNU's readline package: the user would be able to have
 * a complete emacs/vi like line editing system.

 * terminal driven by a tty having -raw)
