Need some help with an x86 PC assembly language project. It needs to be in assembly, Thanks!

Create an assembly program that reads from standard input and prints hexadecimal digits representing the binary bytes of the input (similar to the od --format=x1 command). Have it run with interactive input typed by the user as well as, read in text files. Please include a constant in your program that you can easily change to control the number of hex bytes to display per line.

Output example:

41 6E 64 20 49 20 74 68 69 6E 6B 20 74 6F 20 6D 79 73 65 6C 66 2C OA 57 68 61 74 20 61 20 77 6F 6E 64 65 72 66 75 60 20 77 6F 72 6C 64 21 OA 41 6E 64 20 49 20 74 68 69 6E 6B 20 74 6F 20 6D 79 73 65 6C 66 2C OA 57 68 61 74 20 61 20 77 6F 6E 64 65 72 66 75 60 20 77 6F 72 6C 64 21 OA
