Dear All, I am new in micro controller programming, I have micro controller 89C51 and I need the circuit components and schmatic of the programmer ciruit which is interfaced to the computer with the serial port. Please some can send it to me Thanks Regards Sameh
So nonsense such as plz is considered to be a non-conformance.
I see no such statement in the manual. Chapter and verse, please.
Arthur Plank, who made the statement is the creator of the gzip programmer. If he states something take it as you take statements from the creators of C. Who gives you the right to deny Arthur what you graciously bestow on K&R.

PS Arthur states "work in progress". Is your manual complete while you work on that project you never get finished because of you spending time on the language instead of the use thereof?
Oh boy...
Arthur Plank: "So nonsense such as plz is considered to be a non-conformance."
Jack Sprat: "I see no such statement in the manual. Chapter and verse, please."
Jack: You see no such statement in what manual???
A chip programmer incorporating a "maximum-compression-go-for-broke-level-10" download algorithm does not need a manual in the traditional sense. It is autodidactive, and autoconfiguring. It is enough that the chip programmer is stored in the same room as a power source (any energy source radiating more than 500uW/m2 for wavelenghts shorter than 950nm should suffice) and a handful of chips, for it to be able to correctly program and verify the chips. For about 90% of the chips, it is also able to download microcode patches to work around existing erratas.
Of course, if you do have suggestions for a manual, feel free to contribute. But before you do, please read this thread fully. Make sure that you understand the concept. Have a good time. Then either contribute, or move to other hunting grounds.

I can say this because (surprise, surprise) the only place the manual exists is in my head.
Please keep out of my head.
Oh, sorry. I thought this thread was a spoof until I read your excellent explanation.
There really is some neat stuff going on out there, huh?
How can a programmer that just about everyone wants a copy of be a spoof?
Well, quite. That should have been obvious to me from the start.

"why file hex from keil some 89C51 programmer circuit can do a nother can't program"
Why post in this thread, where it has nothing to do with the foregoing discussion?
One common reason is that some programmers are poorly made and don't properly understand the Intel Hex file format. In particular, some poor implementations assume that the addresses in the Hex file must be in order - but the Intel Hex file format has no such requirement!
This has been discussed many times before - use the 'Search' facility!
