this is microprocessor 8088 80886 course use emu8086 please mention the details of the solution

3) The following questions are set up in view of the Figures (d,e) a) Describe what type of I/O operation is carried out in Figure (d). What are the addresses of data lines, strobe output and busy input in the circuit. Assume that all unused address bits are zero. b) Write a program that will implement the sequence in Figure (e) for the circuit in Figure (d). Character data are held in memory starting at address PRNT_BUFF and the number of characters held in the buffer is identified by the count at address CHAR-COUNT. Write comments and Use minimum number of instructions.
