[Quoting: amit] Hi,I am using DB9 connector. reference circuit down.The program Enable<br />
instruction on AT89S51 does not shows0x69 value on MOSI to confirm <strong>Programming</strong><br />
mode enabled.Can any bodu help?..........Moreover, I am reading 0xff values on alternate<br />
byte addresses not on every byte address after chip erase.e.g. Address Data 0xfa 00 0xfb<br />
0xff 0xfc 00 and so on, and this is conssitent <strong>for</strong> memory location.<br />
Hi, Amit, you have not mentioned asto which driver software you are using <strong>for</strong> db9 socket<br />
and programming 89S51.i wonder whether you have written a driver software. if so I would<br />
be interested to test it .Sarma<br />
I used at89prog s/w. That is written <strong>for</strong> AT89S8252. I changed the instruction set <strong>for</strong><br />
At89S51.<br />

This project worked fine on Windows98 but as soon as I upgraded to WindowsXP, the<br />
programmer is unable to identify the devices. What could be the problem, I used AT89S51.<br />
What is the use of a system file included in the zip file. Please guide. Thanks & regards<br />

I canot do this because my lap top doesn't have the parallel port, it has USB port.<br />
This is the reason I had to re invent the wheel.<br />
Can you help me, why i am not able to seee byte 0x69 on MISO on program enable<br />
instruction?<br />
Is the hardware connection <strong>for</strong> Reset is a problem?<br />
The at89prog can be downloaded from http://jelmer.vernstok.nl/oss/at89prog/<br />
its <strong>for</strong> Linux. You have build the executable with the makefile<br />

i can't manage Linux as i am just new(at my 62nd year) as just started using fedoracore7.<br />
on the other hand if you have winXP,you may try ponyprog at www.ponyprog.com<br />
you study the schematics main and the one supporting 89s53. a combination of these two and<br />
the software given by them will help you manage with the COM port.<br />
I would also be interested in the outcome.
