For downloading a hex file into AT89C51's memory you need a parallel programmer.
You can buy one or to make your own, for example you can find one here: h**p://www.kmitl.ac.th/~kswichit/89prog/index.html

You can use MCU 89xx Programmer, with serial I/F or Parallel I/F to send .hex file
Some resource available for free and commercial.
for example link site:
