answer in 8051 assembly language

2. Write a program that read a switch connected to pl.1. If the switch is on, you will read a sentence of 10 characters from a scanner connected serially to the 8051 and store it in RAM location 30H. When the switch is off, the 8051 will print the ROM location 300H that consists of 20 characters serially. Use 1,200 baud rate. 3. Design a device that will read a scanner connected to it serially and save the characters in a file. When the scanner is not used, the user of this device can print the information stored in the file on to a printer connected serially to this device. The user can choose whether she wants to scan a file or print the information already scanned. Use 19,200 baud rate. 4. Write a code that read characters from a device called line generator connected to the serial port of 8051 and convert the uppercase characters to lowercase. Use baud rate 19,200. 5. Design a device using 8051 to let the user choose between 9,600 or 19,200 baud rates. The user will print serially the information received to it through a device called MINE connected to port 1. The printer is connected to the serial port of the 8051. Force the user first to choose the baud rate, then allow the device to read MINE and print it serially. State all your assumptions. 2.
