read-char-no-hang

["Carl L. Gay" <cgay@skinner.cs.uoregon.edu>]

Forgive me if this is a stupid question, but I can't seem to find the
answer in the documentation...

In MCL2.0b1p3 (loop until (read-char-no-hang)) doesn't return
immediately when I press a character.  Instead it waits until I press
#\Return.  I want to use this for a simple input-with-timeout routine.
Is there some way to fix this?

Reply to me only, *not* the list/newsgroup.  I'll summarize if
necessary.

Thanks.
