		Data lines use a “negative” voltage logic, meaning that a negative voltage on the wire carrying the data signal (RD or TD on a nine-wire connection) is described as “On”, “Asserted”, “Mark”, “Marking”, “1” or “True.” Conversely, a positive voltage on the wire is interpreted as “Off”, “De-asserted”, “Space”, “Spacing”, “0” or “False.”
		Within any byte of data, the receiver is actually applying a clock to measure the elements of the data transmission, and will sample the voltage level within the byte in a manner corresponding to the number of discrete bits of data it expects the byte, along with its framing and possible parity bits, to have.
		The trigger level for the input buffer indicates the number of bytes of data required to be in that buffer before the driver is asked to collect them; the trigger level for the transmit buffer indicates the number of bytes of data remaining in that buffer before the driver is asked to refill it.
