I need to communicate between an RS232 and the UART of an 80C2051 microcontroller in order to program another 8051 chip. I have configured the correct settings for the UART set up, all I would really like to do is send a character from RS232 and view it in hyperterminal, writing the software in C language as opposed to Assembly. does any one know the correct way to do this? I have looked at many code examples and they dont really give much as to how this is done for example sending the character '$' and how it is recieved on UART, and how you can check this is correct using Hyperterminal.
