FTP USING RS232 in Network Lab C++ Programming

To write a program for FTP using RS232 and to verify the text
entered in the file.
ALGORITHM FOR FTP USING RS232
STEP 1: Start the program.
STEP 2: Create a file pointer and a union.
STEP 3: Open another new file with a txt extension.
STEP 4: Enter some text in it and save the file.
STEP 5: Select an option from the choices.
STEP 6: The first option displays data ready.
STEP 7: The second option displays the text in the file.
STEP 8: Stop the program.
