Option	Setting	Description
DTR Polarity	High*	Serial port’s DTR (Data Terminal Ready) signal sent
	Low	from the printer to notify the host computer that it is
		ready to receive data.
		High is standard for most computers; it uses true logic
		(+5 V).
		Low is typically used on nonstandard equipment; it
		uses inverted logic (0 V).
Data Bits	7	Number of data bits in a character.
	8*
		The Data Bits setting must match the
		host computer data bits setting.
		Note
Parity	None*	How the parity bit is used in error checking.
	Even	The parity bit may be checked against the received
	Odd
		character by means of an Even or Odd error checking
		mechanism.
		The Parity setting must match the host
		computer parity setting.
		Note
Stop Bits	2	Number of stop bits in each character. (Stop bits
	1.5	signal the end of a character.)
	1*
		The Stop Bits setting must match the
		host computer stop bits setting.
