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
