description A method, circuit, and system are disclosed. In one embodiment, the method comprises sending a step pulse across a serial advanced technology attachment (SATA) transmission line, determining the length of time the transmission line takes to charge from common mode voltage to supply voltage, and determining whether a device is connected to the SATA transmission line based on the length of the transmission line charge time.
