Digi 90000566_H Options Range=range, Mode=232485, Wires=twofour, Two, Four, Termination=onoff

	set switches
Options	range=range
	The port or range of ports to which this command applies.
	mode={232485}
	Selects the electrical interface of the serial port. The selected value
	determines whether the "wires" and "termination" options are meaningful.
	232
	The serial port uses electrical interface EIA-232. This interface uses
	independent wires to transmit and receive data, which allows data to
	be sent and received between devices simultaneously.
	485
	The serial port uses electrical interface EIA-485. This mode can also
	be used for EIA-422 connections. This interface uses two wires to both
	transmit and receive data. This interface also allows for multiple
	transmitters and receivers to be easily connected together.
	The "wires" and "termination" command options specifically apply to
	serial ports in EIA-485 mode.
	The default is "232."
	wires={twofour}
	Applies when the serial port is running in EIA-485 mode only. Selects the
	number of differential wires used for communication and implicitly
	determines the duplex of the connection.
	two
	The serial port operates in two-wire mode. This mode is a half-duplex
	connection with shared transmit and receive wires.
	four
	The serial port operates in four-wire mode. This mode is a full-duplex
	connection with independent transmit and receive pairs.
	The default is "four."
	termination={onoff}
	Applies when the serial port is running in EIA-485 mode only. Determines
	whether termination and biasing resistors are used across the lines.
	on
	Termination and biasing resistors are enabled across the lines.
	Termination should be set to "on" if this node is an endpoint of the 485
	network. Biasing should be used in at least one unit in a two-wire
	environment.
	off
	Termination and biasing resistors are disabled across the lines.
	The default is "off."
