8086 interfacing with 8251

Problem Statement: 8251

Perform an experiment to establish communication between two 8251 systems A and B. Program 8251 system A in asynchronous transmitter mode and 8251 system B in asynchronous receiver mode. Write an ALP to transmit the data from system A and receive the data at system B. The requirements are as follows: 
Transmission:
• message is stored as ASCII characters in the memory.
• message specifies the number of characters to be transmitted as the first byte.
Reception:
• Message is retrieved and stored in the memory.
• Successful reception should be indicated.
