Sketch the asynchronous frame of an asynchronous serial data communication system transmitting the ASCIl character "X" (upper case) over an RS-232 interface. The frame is transmitted at 1200 baud using 7E1 frame format. Clearly label the mark and space levels (voltages not required), start bit, parity bit (if any), stop bit (or bits) and data bits. Label the MSB and LSB of the data field. Also identify the frame and its period on the diagram.
