Hi,

I had splited my program in "BIOS" + application.
In order to load the application, I will use IAP running inside BIOS part. This will be done by modem connection.

In order to have the same LOADER for factory purposes (ISP) and IAP, I will use the same schema from ISP. I mean the same HEX format conventios plus some proprietary instrutions sets.

The IAP part will be done in a criptographic way.
The ISP part will worke as Magic Flash. I will not use Magic Flash for factory production, because I need to automate same things and include Serial Numbers and some data more. Magic Flash doesn't do these things in a easy way.

MY QUESTION:

For 89C51RD2 ISP, how does each record finish ?

I mean, do I need to finish each record transmission with CR + LF. This is not so clear from the AN461.
