Abstract
A peripheral communications terminal and interfacing method whereby host terminal intercommunication can proceed when the communications terminal is off-line without requiring host driver interface modification. This communications terminal incorporates a communications enabling unit that selectably uses DTR signaling or similar handshaking to notify the host whether data can be received. This communications enabling unit is set to either a first 'busy' mode indicating that receipt of streaming data is not possible when the processor of the communications terminal, which possesses at least a printing function, cannot further process data, or a second 'override' mode which allows receipt of incoming data to continue even when the processor cannot process data. When the communications enabling unit is set to the override mode and a state in which the terminal processor cannot process data has occurred, the communications terminal control method of the present invention is able to automatically notify the host of such status.
