	Menu item	Description
	Protocol	Selects the hardware and software handshaking settings for the serial port
	DTR	Notes:
	DTR/DSR
		• DTR is the factory default setting.
	XON/XOFF
		• DTR/DSR is a hardware handshaking setting.
	XON/XOFF/DTR
	XONXOFF/DTRDSR	• XON/XOFF is a software handshaking setting.
		• XON/XOFF/DTR and XON/XOFF/DTR/DSR are combined hardware and
		software handshaking settings.
	Robust XON	Determines whether the printer communicates availability to the computer
	Off	Notes:
	On
		• Off is the factory default setting.
		• This menu item applies only to the serial port if Serial Protocol is set to
		XON/XOFF.
	Baud	Specifies the rate at which data can be received through the serial port
	9600	Notes:
	19200
		• 9600 is the factory default setting.
	38400
		• 138200, 172800, 230400, and 345600 baud rates are only displayed in the

	Honor DSR	Determines whether the printer uses the DSR Signal
	Off	Notes:
	On
		• Off is the factory default setting.
		• DSR is a handshaking signal used by most serial cables. The serial port uses
		DSR to distinguish data sent by the computer from data created by electrical
		noise in the serial cable. The electrical noise can cause stray characters to
		print. Set this to On to prevent stray characters from printing.
