You probably want to use the C library's "termios" functions to control
the terminal associated with stdin. Try `man cfmakeraw' for more
information.

You'll also need scheme_get_port_fd() to go from a Scheme port to a
file descriptor. (Yep, I see the typo in the docs for that one... fixed
in SVN.)
