In using IBM 3277 terminals characters typed at the keyboard are not buffered in the head. Since the terminal is connected to the host machine via a simplex line, characters typed while the head is not listening to the keyboard are lost. This occurs if the host is transmitting to the terminal, or the terminal is in input inhibited mode.
