X.3 Parameter	Description
4 - Idle Timer	Specifies a timer duration interval in units of
	1/20 of a second. If the time between characters
	entered at the terminal exceeds the specified
	timer value, the packet being assembled by the
	PAD is automatically transmitted. The range is 0
	through 255. If 0 is specified, there is no idle
	timer and packets will never be transmitted due
	to a time-out.
5 - Anc Device	The ancillary device control parameter permits
Control	flow control toward the terminal by the PAD. The
	PAD indicates its readiness to receive characters
	from the terminal by transmitting X-ON (DC1) or
	X-OFF (DC3) to the terminal. 0 indicates that
	flow control by the PAD is not operational, and 1
	permits flow control by the PAD.
