If you call it supported. If you call that typeahead.
BTW ksh on my machine cannot process typedahead edit commands.

How about, typeahead for passwords?
How about, screen formatting programs?
I just got out of a meeting with our vendor about this very subject-
the terminal drivers are deliberately programmed against us. When
you do disk stuff, the input doesn't start until the process asks:
terminal stuff is crammed willy-nilly into the memory, so the controller
doesn't have to be annoyed by the processes.
