Serial Ports: Difference between revisions

:is theThe speed at which the serial line switches between it's two states. This is not equivalent to bps, due to the fact there are start and stop bits. On an 8/N/1 line, 10 baud = 1 byte. Modems are more complex than plain serial lines due to having multiple waveforms, but for the purposes of OSDev this is irrelevant.

:theThe NULL bit(s) sent between each character to synchronize the transmitter and the receiver.

:forFor Universal Asynchronous Receiver/Transceiver: the chip that picks a byte a send it bit per bit on the serial line and vice versa.
