       Handle the tty line connected to standard  input.   Without  arguments,
       prints  baud  rate, line discipline, and deviations from stty sane.  In
       settings, CHAR is taken literally, or coded as in  ^c,  0x37,  0177  or
       127; special values ^- or undef used to disable special characters.
