This is because of the insane way termio(7) has been implemented.
If you read carefully the section describing ICANON, MIN, and TIME,
you will see that your EOF character, (ascii 04), determines how many
characters must be typed before a read returns when canonical processing
(cooked mode) is disabled.  If you don't understand this section, just
set your EOF character to be ^A.
