Kyocera FS-6700 manual Prescribe IIe Frpo D0 command, H7 Buffer nearly-empty threshold

C.3. RS-232C/RS-422A Protocol

H7: Buffer nearly-empty threshold

This is a percentage from 0 to 99. The factory setting is 70.

The factory settings of the buffer nearly-full and nearly-empty thresholds (H6 and H7) are subject to change without notification.

The gap between the nearly-full and nearly-empty thresholds allows the computer to send a fairly large amount of data in a continuous stream.

H8: Received-data buffer size

This is the size of the input buffer, specified in units of 10 K bytes. The factory-set value is 6 meaning 60 K bytes.

PRESCRIBE IIe FRPO D0 command

The PRESCRIBE IIe FRPO D0 command is provided to allow manipulating XON/XOFF when an error has occurred on the serial interface. The following table summarizes the error status corresponding to different D0 values.

		Serial interface error
		error not handled	error handled
Timing of XON transfer	XON sent every 3-5	D0 = 0 (default)	D0 = 1
to host while Ready or	seconds
Waiting
	XON not sent	D0 = 10	D0 = 11
