WHICH "8051", there are 100s of them. What circuit ?

What's the program you are trying to write ? Find a nice simple piece of code to initialise the timers, and set up serial comms, then dump a single character to the serial port.

will proload4.1 work for AT89S52 home made programmer?? please reply fast
Why ?
Like I said, and L. has confirmed WHAT are you trying to program, and what with ?

Atmel have the Flip programmer.
NXP have the Flashmagic programmer, both require a working serial port on your PC and on your 8051 board to work.
