Maybe nobody understood the problem, i wont post the program code cause i think it is difficult to understand, i will just need this information cause i think im missing some code for the serial port, i need
someone to provide the Assembler code for initialating the serial port in mode 2 at 2400 bauds and a subroutine that will read and other that writes, can u please add an external interrupt to.

I will really thank everybody in mi last post i have the code that is giving me headaches because i dont know what is wrong with it, if you want to check it its just below thist post.
