No, it shouldn't be displayed on the screen, only if it's echoed back by the other end - this is normal, and proves it's all working if the character appears on screen.
But how come nothing happens when I press a key (I am checking using an oscilloscope the serial port output). Nothing comes up on the screen, nor is anything transmitted through the port??
Do you have handshaking set to NONE.
