serial communication does not works between two AT89c512 PI24 microcontroller without max232 weather there is possibilities for communication or we must use max232?
I connected 1kohm resistor in serial with both txr and rxr still it is not working can u make a little bit clear of it?
I do not know if micro (u) can, but ....
well, who knows. It could be your PIG code or your '51 code or your connections. AH, just remember - becuse of identical names, most routing software tend to connect Tx to Tx instead if Tx to Rx, YES, I got caught on that one once :(.
"it does not work, help" is NOT a substitute for debugging although it seems many believe so.

No, I can not waste my time to be more clear. Notice the difference in length of your post and mine. You don't waste time writing much - despite this being _your_ problem. Why should I invest time writing more when this isn't my problem?
People respond to facts. You don't post facts. People then don't want to cover all bases just in case.
