Star Micronics CBM-820 manual GS I n, Description

GS I n

[Function]	Sends Printer ID
[Code]	ASCII			GS	I	n
	Hexadecimal			1D	49	n
	Decimal			29	73	n
[Range]	1	n	3, 49	n	51

[Outline]	This command sends the printer ID listed in the table below, depending on setting of n, when it
	is executed.
	n	Type of Printer ID	Specification	ID (Hex.)
	1, 49	Model ID	CBM-820	02H
	2, 50	Type ID	See Table below
	3, 51	ROM version	Depends on ROM version
[Caution]	• If DTR/DSR control is selected and the memory switch 4-5 is set to 0, the printer sends only 1
	byte after confirming that the host is ready to receive (the DSR signal status is Space).
	If the host is not ready (the DSR signal status is Mark), the printer will wait until it will be ready
	to receive. If XON/XOFF control is selected or the memory switch 4-5 is set to 1, the printer
	will send only 1 byte without confirming the DSR signal status.

•Since this command is executed at deployment of the reception buffer, there may be a delay between command reception and status sending, depending on the reception buffer condition.

•If ASB is enabled by GS a, it is necessary to distinguish the status by this command from that of ASB. See “6. Interface” for how to distinguish them.

•The ROM version may be changed.

•If n goes beyond the range, this command will be ignored.
