My microprocesser wont recieve data from my comp, i've used hyparterm, telnet, and linkit-123 but none of them wont transemit data to my MPu. yet i see a recieve mode in the Link menu why?
more words, please
a few basic questions 1) you do have a MAX232(equivalent) between the UART and the 'compensator', I hope 2) do you get nothing or garbage if you constantly transmiy 'U'? 3) are you cabled correctly (RS-232 cables comes in 'straight' and 'crossed') and you must use the cable that match yur connections at the uC

"My microprocesser wont recieve data from my comp"
OK, so it's a pretty good guess that "comp" means "computer" here - but having to guess doesn't help. The more clear and complete you make your description, the more likely you are to get good replies!
"i've used hyparterm, telnet, and linkit-123"
Hyperterminal is a plain text terminal emulator; Telnet is an internet protocol; I have no idea what "limkit-123" is.
Are you sure that you had all these tools correctly configured - speed, parity, handshaking, etc?
"but none of them wont transemit data"
How do you know that they won't transmit?
Your first step has to be to determine where the problem is:
Is the PC transmitting correctly? Is the data reaching the microcontroller's pins correctly (ie, correct & working cabling, correct & working RS232 transceiver, correct & working board connections, etc)? Has your software correctly configured the UART, etc?
"i see a recieve mode in the Link menu"
What is a "receive mode"?
What "link menu"?
YEAAAAAAHHHHHH
I fixde it bcoz teh cable was not in.
