Hi I want something like below.
while(see if esc key is pressed) reading serial port; writing to another serial port;endcode;code;fclose(serialports);
where the while loop continues to execute until the escape key is pressed. Currently i am doing it with while(1). but when i have to end the program i have to press ctrl+c. Which terminates the program and the code where the ports are to be closed is not executed. So i want to get out of the while loop when escape is pressed and the code below the while loop is also executed.
