Citizen CBM1000 manual FS g3

• When the XON/XOFF control is selected, all the codes are sent continuously without verifying that the host can receive the data. Data that has been sent is always continuous except for

	the XOFF code.
	• When parallel interface is used, the size of the buffer for
	sending data (The buffer that stores all data to be sent except
	for ASB status) is 99 bytes. Data which exceeds 99 bytes, will
	be discarded.
	• Data can be written into the download user NV memory using
	the FS g3 command.
	• There may be a delay between receiving this command and
	storing the data depending on the state of the receiving buffer.
[Caution]	• After the header is sent, all data will be sent without verifying
	whether the host can receive the data or not. Therefore, the
	available space in the receiving buffer of the host should be
	more than (The number of sent data+2) in order not to lose
	data during the execution of this command.
	• While data is being sent, real time commands (Commands
	with a DLE extension) will be ignored. And even if the ASB
	function is validly selected, ASB status will not be sent while
	data is in the process of being sent. Therefore, it is not possible
	to check the change in the printer state by checking its status.
	The user must pay attention to this.
