I want to send text message to Rs-232 serial cable by using hyper terminal. Can any one help me ??
Sending the message is easy - as soon as you press a key in Hyperterminal it will send the character out of the selected COM port at the selected speed, with the selected number of data bits, etc (but pay attention to Flow Control...)
Note that Hyperterminal neither knows nor cares where this transmitted data goes to; it just transmits it - it is completely irrelevant what (if anything) is connected to the COM port...
At the microcontroller end, you will need to convert the RS232 levels to suitable logic levels, and connect to a UART (or USART) input on the microcontroller.
Then you will need to write suitable software in the microcontroller to handle the UART and receive the characters.
Again, the microcontroller neither knows nor cares where this received data originated; it just receives it - it is completely irrelevant what was used to send it.
The Datasheet and other manufacturer Documentation will tell you what needs to be done to use a particular UART on a specific microcontroller.
This is basic serial comms - there is an absolute ocean of information readily available about this on the web. Just about every development kit or evaluation module you will find will have an RS232 interface and examples on how to use it...
