2)When the BDC-1000 is connected in a stand-alone : [MARK] : The host is not ready to receive data [SPACE] : The host is ready to receive data

This indicates whether the display is ready to receive data (*2).

[SPACE] The display can receive data. [MARK] The display cannot receive data. [DTR MARK]

DTR goes to MARK under the following conditions :

①The period from when the power is turned on to when the display first becomes ready to receive data.

②When the self-test is executed.

③When the remaining space in the receive buffer becomes 40bytes or less (buffer-full state).

④When [DSR MARK] is on, if the printer is selected by a peripheral device command. (When the BCD-1000 is connected with the data pass through.)(*1)

DTR goes to SPACE under the following conditions :

①When the display first becomes ready to receive data after power-on.
