I don't know of any UNIX implementation that provides such a feature,
although it is doable and I've often wished I had it (its utility is
not limited to deferred-echo terminal handlers).

The nearest equivalent on UNIX is to type the interrupt key, which
in many cases will flush type-ahead.  Unfortunately it also sends
a signal to the process group!
