Driver support for Emulating Parallel ATA mode and Native Serial ATA mode controllers is separate and distinct as these modes appear as two different and unique ATA interconnects. There will be some Serial ATA controllers that will want to implement both Emulating Parallel ATA and Native Serial ATA modes on the same device, which is acceptable. It is not acceptable to use both modes at the same time in Windows. Additionally, loading parallel ATA drivers on a Serial ATA controller in Native Serial ATA mode and vice versa will have disastrous results.

Serial data is made up of high and low voltage pulses strung together, similar to an electronic Morse code. Each string of voltage pulses forms a message. The transmission of data occurs through a wire or "bus" for predetermined time intervals. Devices like modules (... referred to as nodes) connected to the bus can then share information by transmitting and receiving these messages.

Serial ATA is point to point, meaning only one storage device can be connected to a single Serial ATA cable. Parallel ATA has a shared channel and can connect up to two storage devices on a single cable.

When programming serial interfaces on Unix, there is one phrase - line discipline - which can drive programmers crazy. The line discipline provides the hardware-independent interface for the communication between the computer and the terminal device. It handles such things as editing, job control, and special character interpretation, and performs transformations on the incoming and outgoing data.
