Write an ALP to transfer the message “CORONA” serially at 2400 baud rate, 8-bit data, 1- stop bit. Do it continuously.

(a) Suppose that the BI/RBO input line was connected to ground on the 74LS47 BCD- to-seven segment decoder and all other input lines were connected as shown in Figure 3. Determine the effect this would have on the display. (b) Assume that the switches in Figure 3 are set to binary 1000, but the display shows a zero. What are possible causes for this error?
