\usage{
alarm()
}
\details{
  \code{alarm()} works by sending a \code{"\\a"} character to the console.
  On most platforms this will ring a bell, beep, or give some other signal
  to the user (unless standard output has been redirected).

  As from \R 2.14.0 it attempts to flush the console (see
  \code{\link{flush.console}}).
