(Everybody: please include a return address.  I don't have domain uucp!)

On BSD Un*x you can use the "select()" call to wait for a stream to become
ready; if the "timeout" parameter is zero (NOT a zero pointer!) the call
will return immediately.  I have no idea what the performance is compared
to ioctl(), I'd guess it is less device-dependent than ioctl().

On some (many?) PCs, you can read the keyboard or controller directly.

    ;-D on  (Not an answer, but at least not a question!)  Pardo
