hi Dan.

on the 8051´s side I mean the assembler code, (i have trouble setting the registers, I get messed). I´ve already implemented the hardware, to comunicate my 8051 to the PC using RS232, but I don´t know how to send or recive data from the pc

My object is to send the whole EEPROM to the PC modify it, and send it back to the 8051

whatever you can explain me or as you said, donate I will be extreamly thankfull.

PS: I´ve haven´t practice my englich since long, forgive mispelligs
