Make sure that you have selected the correct COM port on the PC which is connected to the UCM

On the UCM, look at the green D11 led. This should blink when a character is received from the PC. If it does not blink, that means the character is not getting into the UCM. This may be because of the cable, the port, the connection between the Rs232 submodule and the base UCM, or even a faulty Rs232 submodule
