    UART communication through RX pin


      Hello there,

      I am using a CY8CKIT-042-A pioneer kit.

      I have a project using the UART. and have it tested successfully using Putty terminal. Now I tried to send the same signal (same data pattern as I saw on the TX pin when using Putty terminal) through UART's RX pin. But nothing happened.

      I must have missed something. Do I need to instruct the program in the main.c to watch the RX pin or does the program constantly monitor it?

      Please help.
