Serial asynchronous communication ports are widely used in contemporary computers to connect a terminal (keyboard and display) or a printer to the computer. The signaling protocol typically employs 1 or 2 start bits and a single stop bit to encapsulate each byte. A transmitter sends start bits to the receiver to indicate that a byte is about to be transmitted. The 8 bits in the byte are then transmitted, followed by a single stop bit. How many bytes per second can be transmitted over a 9,600-baud serial line using this protocol? What is the percentage of time spent on transmitting overhead bits?
