Hallo friends,
I want to change a table in a program

UNIT1:
I wrote a assembler-program with AT89S52 (4kb). The program includes a table and 3 lock-bits are set. I program per ISP (AEC_ISP).
Hardware and program works fine. Every cyklus the table is send out per V24 with 9600Bd.

UNIT2:
a service-unit with AT89S52 recieves the table-bytes and I see the table with 2x16 LCD.
I want to change the table-bytes and this works fine.

The program of UNIT2 have 3 parts:
program1 of unit1, the changed table
and program-parts to change and to show the changes.
I want to send back program1 and the changed table per ISP or V24.

My question: How I can do this?

With regards
Manfred
