It sounds like what you want is raw terminal input.  Non-blocking
input is different: it means that (read-char) will return immediately
(possibly throwing an exception) even if there is nothing to read yet.

For raw terminal input, you'd need tcsetattr, which doesn't seem to be
directly available in Guile.  But maybe you can use the readline
module to do what you want.
