Lantronix 900-653-R manual Baud Rate, Data Bits, Parity, Stop Bits, Enable Packing, Idle Gap Time

				5: Configuration Using Web Manager
	Baud Rate		The unit and attached serial device, such as a modem, must agree on a
			speed or baud rate to use for the serial connection. Valid baud rates are
			300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, and
			230400 baud. Additionally, 921600 and 460800 baud rates are available
			when CPU is set to High. The default setting is 9600.
	Data Bits		Indicates the number of bits in a transmitted data package. The default
			setting is 8.
	Parity		Checks for the parity bit. The default setting is None.
	Stop Bits		The stop bit follows the data and parity bits in serial communication. It
			indicates the end of transmission. The default setting is 1.
Pack Control
	Enable Packing	Select to enable packing on the xDirect.
		Two firmware-selectable packing algorithms define how and when packets are
		sent to the network.
		The standard algorithm is optimized for applications in which the unit is used in
		a local environment, allowing for very small delays for single characters, while
		keeping the packet count low.
		The alternate packing algorithm minimizes the packet count on the network
		and is especially useful in applications in a routed Wide Area Network (WAN).
		Adjusting parameters in this mode can economize the network data stream.
		Disabled by default.
	Idle Gap Time	Select the maximum time for inactivity. The default time is 12 milliseconds.
	Match 2 Byte Sequence	Use to indicate the end of a series of data to be sent as one group. The
		sequence must occur sequentially to indicate end of the data collection to the
		xDirect. The default setting is No.
	Match Bytes	Use to indicate the end of a series of data to be sent as one group. Set this
		value to 00 if specific functions are not needed.
	Send Frame Immediate	After the detection of the byte sequence, indicates whether to send the data
		frame or the entire buffer. Select Yes to send only the data frame. The default
		setting is No.
	Send Trailing Bytes	Select the number of bytes to send after the end-of-sequence characters. The
		default setting is None.
Flush Input Buffer (Serial to Network)
	With Active Connect			Select Yes to clear the input buffer with a connection that is initiated from
				the device to the network. The default setting is No.
	With Passive Connect			Select Yes to clear the input buffer with a connection initiated from the
				network to the device. The default setting is No.
	At Time of Disconnect			Select Yes to clear the input buffer when the network connection to or
				from the device is disconnected. The default setting is No.
Flush Output Buffer (Network to Serial)
	With Active Connect			Select Yes to clear the output buffer with a connection that is initiated from
				the device to the network. The default setting is No.
	With Passive Connect			Select Yes to clear the output buffer with a connection initiated from the
				network to the device. The default setting is No.
